  • Promotion of Cross-Linking and Resulting Suppression of Tar Evolution in Potassium-Catalyzed Pyrolysis of Woody Biomass

    Acid-washed woody biomass (cedar) was impregnated with K<inf>2</inf>CO<inf>3</inf> and then pyrolyzed at 550 °C in a fixed bed reactor, in which extra-particle pyrolysis of volatile matter was well suppressed. The tar yield decreased from 0.42 to 0.034 kg/kg-daf with increasing K loading (m<inf>K,0</inf>) within the range of 0-5.0 mol K/kg-daf. The K-catalyzed condensation by dehydration, dehydrogenation, and dealkylation reactions formed H<inf>2</inf>O, H<inf>2</inf>, and gaseous hydrocarbons (GHCs), respectively, producing intermonomer-unit cross-links (MUCs) and thereby decreasing the yield of tar as monomers and oligomers. According to the conversion of K<inf>2</inf>CO<inf>3</inf> (34-57%), three catalytic cycles were estimated with the conversion/regeneration of K<inf>2</inf>CO<inf>3</inf>, KOH, and alkoxides/phenoxides, formation of inter-MUCs and that of the above-mentioned gases. The relationship between the amount of inter-MUCs formed during the pyrolysis (assumed to be 30% of that of H<inf>2</inf>O, H<inf>2</inf>, and GHCs on a molar basis) and reduction in the tar yield was considered by applying the Bethe lattice model, which is often employed for analyzing degradation and repolymerization of polymer, coal, and biomass. The model described the above relationship semiquantitatively. The efficiency of the K loading for the tar reduction, represented by the derivative of the tar yield (Y<inf>tar</inf>) with respect to m<inf>K,0</inf>, i.e., dY<inf>tar</inf>/dm<inf>K,0</inf>, was decreased by a factor of about 340 while m<inf>K,0</inf> increased from 0 to 5.0 mol K/kg daf. Such a large factor was explained by decreases in the two derivatives, dY<inf>tar</inf>/dY<inf>inter-MUC</inf> (Y<inf>inter-MUC</inf>; the amount of inter-MUCs) and dY<inf>inter-MUC</inf>/dm<inf>K,0</inf>, quantitatively. The decrease in the dY<inf>inter-MUC</inf>/dm<inf>K,0</inf> (factor ≈ 30) was mainly due to the depletion of functional groups that underwent condensation reactions while that in the dY<inf>tar</inf>/dY<inf>inter-MUC</inf> (factor ≈ 11.6) arose from the nature of network polymer such as approximation by the Bethe lattice.

  • Staged Conversion of Potassium-Loaded Biomass into Syngas by Continuous Pyrolysis and Low-Temperature Reforming/Gasification with CO2 and O2

    CO<inf>2</inf>-O<inf>2</inf>-blown gasification of dry biomass can potentially produce syngas with maximized yield of CO, in other words, the rate of carbon recuperation. Among various types of gasification, staged conversion consisting of pyrolysis, volatile reforming, and char gasification is expected to give the highest cold gas efficiency (i.e., recuperation rate of biomass chemical energy) if endothermic pyrolysis is driven by the heat of syngas from the reforming/gasification. Catalytic char gasification, if operated at a temperature well below 800 °C, may enable the avoidance of ash-related troubles such as clinker formation/accumulation in the gasifier while achieving fast and complete char conversion to syngas. We simulated numerically the above staged conversion of woody biomass with potassium (K) and CO<inf>2</inf>-O<inf>2</inf> as the catalyst and gasifying agent, respectively, and then experimentally by applying screw-conveyor pyrolysis at 550 °C and downdraft gasification/reforming at 730 °C. It was revealed that the biomass with 1.0 mol-K/kg-dry loading was converted to gas completely by applying CO<inf>2</inf>/C and O<inf>2</inf>/C molar ratios of ≥0.42 and ≈0.30, respectively. The CO yield and apparent cold gas efficiency were both 94% on biomass carbon and LHV bases, respectively. The concentrations of residual heavy tar (molecular mass >200) and light tar (<200) were 0.1-0.7 and 0.7-8.5 mg/Nm<sup>3</sup>-dry, respectively, over the range of CO<inf>2</inf>/C ratios (0.42-0.72) investigated. The carbon conversion to gas and tar concentrations were sensitive to the K loading, gasification/reforming temperature, CO<inf>2</inf>/C ratio, and O<inf>2</inf>/C ratio.

  • Effect of Initial Potassium Catalyst Concentration on Its Activity and Fate in CO2 Gasification of Lignite Char

    K-catalyzed gasification of char and carbon has been studied for more than 40 years while many different types of relationships between specific rate of gasification (r<inf>sp</inf> = (Formula presented), X; char conversion) and K concentration in gasifying char/carbon (C<inf>K</inf>) have been reported. This work explored the mechanism causing such diversity in the r<inf>sp</inf>-C<inf>K</inf> profile. An ash-free lignite was impregnated with K<inf>2</inf>CO<inf>3</inf>, devolatilized, and then gasified with CO<inf>2</inf> at 800 °C and C<inf>K</inf> at the start of gasification (C<inf>K,0</inf>) of 0.15-2.66 mol-K/kg-daf-char. C<inf>K</inf> was accurately determined by measuring the K volatilization rate as a function of X. For C<inf>K,0</inf> = 0.15, r<inf>sp</inf> increased linearly with C<inf>K</inf> while the K catalyst activity (k<inf>c</inf>′ = r<inf>sp</inf>/C<inf>K</inf>) remained unchanged at 0.013 min<sup>-1</sup> mol-K/kg-daf-char<sup>-1</sup>. The K species underwent transformation to much more active catalyst (k<inf>c</inf>′ ≈ 0.130 min<sup>-1</sup> mol-K/kg-daf-char<sup>-1</sup>) for C<inf>K,0</inf> = 0.64-2.66, where the r<inf>sp</inf>-C<inf>K</inf> profile was independent of C<inf>K,0</inf>, and r<inf>sp</inf> reached an upper limit due to saturation of gasifying char matrix with the catalyst. The catalyst transformation also occurred for C<inf>K,0</inf> = 0.28-0.39 while k<inf>c</inf>′ of the transformed catalyst was steady at 0.03-0.08 depending on C<inf>K,0</inf>. Thus, the variety of the r<inf>sp</inf>-C<inf>K</inf> profile arose from that in C<inf>K,0</inf>. Higher C<inf>K,0</inf> led to greater dX/dt and then dC<inf>K</inf>/dt under a steady supply of oxygen (as CO<inf>2</inf>) that anchored K on the char surface, allowing atomic-level dispersed C-O-K and/or K<inf>2</inf>CO<inf>3</inf> to transform into clusters consisting of K<inf>x</inf>O<inf>y</inf>(CO<inf>2</inf>)<inf>z</inf> (y/x > 0.5, z/x ≈ 0.16). The most active cluster was formed even during the period of devolatilization for C<inf>K,0</inf> > 1.69. Increasing C<inf>K,0</inf> from 0.15 to 2.66 (by a factor of 18) resulted in shortening of the time required for X = 0.50 and 0.99 by factors as large as 1/200 and 1/100, respectively, due to the above-mentioned C<inf>K,0</inf> effect on the r<inf>sp</inf>-C<inf>K</inf> relationship.

    Water contamination by Endocrine Disrupting Chemicals (EDCs), such as progesterone, is a significant environmental concern. This study uniquely investigates the efficacy of synthesized molybdenum disulfide (S-MoS<inf>2</inf>) compared to commercial molybdenum disulfide (C-MoS<inf>2</inf>) for progesterone removal from water. Batch experiments evaluated the removal efficiency of both types under various dosages and pH conditions. Preliminary results indicate that S-MoS<inf>2</inf>achieves 12.8% higher removal efficiency than C-MoS<inf>2</inf>. This results of the enhanced properties of S-MoS<inf>2</inf> attributed to its synthesis. Dosage experiments showed a 10.7% improvement at an optimal dosage of 20 mg/L (87.8% vs. 79.3%). Additionally, pH variation experiments revealed the highest removal efficiency at pH 7, with a 14.8% improvement (89.3% vs. 77.8%). These findings highlight the superior performance of S-MoS<inf>2</inf>, demonstrating its potential for effective progesterone removal in water treatment applications. This research is the first of its kind to compare synthesized and commercial MoS<inf>2</inf> for this purpose, marking a significant advancement in the field of water treatment.

  • Control of Reactivity of Formed Coke from Torrefied Biomass by Its Washing with Torrefaction-derived Acidic Water

    Torrefaction, pulverization, hot briquetting, and carbonization in sequence successfully produce highstrength coke from woody biomass. This method was further improved by introducing washing of torrefied biomass with acidic water from torrefaction before briquetting. The primary purpose of the washing was to remove alkali, and alkaline-earth metallic species of which catalyses were responsible for high reactivity of the coke. The acidic water (AW) from 275°C torrefaction of Japanese cedar contained 12, 0.9, and 39.4 mass% of acetic and formic acids, and the other organic compounds, respectively. A simulated AW (SAW) was prepared with the same composition as that of AW. SAW with pH of 1.95 removed 96-97% of K, Mg, and Ca and 48% of Na from the torrefied cedar. These removal rates were higher than those by washing with an aqueous solution of acetic acid, hydrogen chloride, or oxalic acid with pH of 2.35, 1.05, or 0.77, respectively. Organic compounds dissolved in SAW helped water and acids penetrate the matrix of the cedar. The washing with SAW increased the tensile strength of coke from 16 to 21 MPa by promoting volumetric shrinkage of the briquette during the carbonization and then particle bonding and coalescence. More importantly, the washing greatly reduced coke reactivity. The times required for gasifying 50% and 99% of coke with 50 kPa CO<inf>2</inf> at 900°C, t<inf>0.50</inf> and t<inf>0.99</inf>, respectively, were extended by factors of 24 and 46, respectively. It was thus demonstrated that the coke reactivity was controllable over such a wide range.

    In continuation of our previous study on production of high-strength metallurgical coke from torrefied softwood (cedar), we studied coke production from a mixture of torrefied cedar (TC) and noncaking coal by pulverization to sizes <100 μm, mixing, binderless hot briquetting, and carbonization. These sequential processes produced coke with a tensile strength of 5-17 MPa, which was equivalent to or greater than that of conventional coke (5-6 MPa), from TC-coal mixtures over the entire ranges of TC mass fraction in briquette of 0-100%, torrefaction temperature of 250-300 °C, and choice of coal (sub-bituminous or medium-volatile bituminous coal). The mixing of TC and coal hindered densification of coke due to hindrance of shrinkage of more-shrinkable TC-derived particles during the carbonization under many of the conditions. Nevertheless, positive synergy occurred in the coke strength at TC mass fractions of over 50%, where coal-derived particles were dispersed in the matrix of TC-derived particles, bonded to them during the carbonization, and behaved as a reinforcement of the matrix. The bonding between TC-derived and coal-derived primary particles was revealed by scanning electron microscopy. Copulverization of mixed TC and coal to sizes <40 μm before the briquetting gave cokes having strengths as high as 23-28 MPa. The fine pulverization increased the frequencies of mutual bonding of TC-derived particles and coal-derived particles and bonding between TC-derived and coal-derived particles per coke volume. The strength of coke from the TC-coal mixture generally followed volume-based additivity of strengths of cokes from TC and coal. This was realized by mixing primary particles of TC and coal within ≈10 μm scale or even smaller.

    Water contamination by ciprofloxacin (CIP) is a global and emerging issue because it increases the risk of infection by antimicrobial resistant bacteria. CIP removal from water by iron nanoparticles (Fe<sup>0</sup>) with the presence of oxalate hasn't been reported yet. The present study demonstrated that the addition of oxalate to Fe<sup>0</sup> nanoparticles improved the removal of 100 mg L<sup>−1</sup> of CIP from 45.04% to 95.74% under the following optimum conditions: [Fe<sup>0</sup>] = 0.3 g L<sup>−1</sup>, [oxalate] = 0.3 mM, initial pH = 7, and temperature = 25 ℃. Furthermore, the experimental results illustrated that high concentrations of dissolved oxygen in the aqueous solution greatly decreased the removal efficiency of CIP by (Fe<sup>0</sup>/oxalate) system from 97.69% (N<inf>2</inf> atmosphere) to 67.47%. Similarly, the performance of (Fe<sup>0</sup>/oxalate) system declined from 95.43% to 85.23% because of increasing the ionic strength of the solution from 0 to 100 mM. In contrast, the influence of humic acid (0 – 40 mg L<sup>−1</sup>) on the removal of CIP by (Fe<sup>0</sup>/oxalate) system was neglectable. Also, the negative impact of coexisting ions on the competence of (Fe<sup>0</sup>/oxalate) system was in the following order: Mg<sup>2+</sup> > NO<inf>3</inf><sup>–</sup> > SO₄<sup>2-</sup> > Ca<sup>2+</sup> > CO<inf>3</inf><sup>2–</sup> > K<sup>+</sup>. In addition, the desorption experiments and the results of SEM-EDS, XRD, and FTIR revealed that physisorption and chemisorption were responsible for CIP removal by (Fe<sup>0</sup>/oxalate) system as the addition of 0.3 mM of oxalate boosted the surface complexation between Fe<sup>0</sup> nanoparticles and the carboxylic, ketone, and piperazinyl groups in CIP. These results were supported by the outcomes of kinetics, isotherm, and thermodynamic analysis. Moreover, oxalate addition significantly reduced the treatment cost of 1 L of 100 mg L<sup>−1</sup> of CIP and the generated sludge by approximately 55.68% and 57%, respectively. Finally, this study proved that (Fe<sup>0</sup>/oxalate) system is inexpensive, practical, and more efficient than most of the reported Fe<sup>0</sup>-based systems with a maximum adsorption capacity of 294.66 mg g<sup>−1</sup>.

    The antibiotic ciprofloxacin (CIP) is recognized as a contaminant of emerging concern because its persistent occurrence in water accelerates the growth of deadly antimicrobial resistance genes (AMRs). For the first time, the conventional precipitation technique was thermally modified to produce hybrid magnesium hydroxide/magnesium oxide nanorods [Mg(OH)<inf>2</inf>/MgO] for efficient and rapid adsorption of CIP from water. The successful synthesis of Mg(OH)<inf>2</inf>/MgO was confirmed by the outcomes of TEM, EDS, XRD, and FTIR analysis. Mg(OH)<inf>2</inf>/MgO exhibited an extraordinary capability to adsorb CIP from water regardless of CIP initial concentration where more than 97% of 200 mg L<sup>−1</sup> of CIP was promptly eliminated within 30 min by 0.1 g L<sup>−1</sup> of Mg(OH)<inf>2</inf>/MgO under neutral pH and room temperature. These results clearly state that Mg(OH)<inf>2</inf>/MgO is at least 2-fold efficient and 20-fold faster in removing CIP than the reported nanomaterials with exceptional adsorption capacity higher than 1789 mg g<sup>−1</sup>. FTIR analysis for the spent Mg(OH)<inf>2</inf>/MgO revealed that bridging complexation with carboxylic group and electrostatic attraction with the positive amine group are the responsible mechanisms for CIP adsorption by Mg(OH)<inf>2</inf>/MgO. Moreover, simulated CIP-contaminated river water was efficiently treated by Mg(OH)<inf>2</inf>/MgO which proves the promising performance of Mg(OH)<inf>2</inf>/MgO in field scale applications.

    This work presents the selective production of the versatile bio-based platform levoglucosenone (LGO) using deep eutectic solvents (DESs) as catalysts during cellulose pyrolysis. Among 18 types of DESs examined, those containing p-toluenesulfonic acid as a hydrogen bond donor possessed the requisite thermal stability for use in the pyrolysis of cellulose. When those DESs were combined with cellulose, the pyrolysis temperature could be reduced which led to greater selectivity for LGO, the highest yield being 41.5% on a carbon basis. Because of their thermal stability, the DESs could be recovered from the pyrolysis residue and reused. The DESs recovery reached 97.9% in the pyrolysis at a low temperature with the LGO yield of 14.0%. Thus, DES-assisted cellulose pyrolysis is a promising methodology for LGO production.

    This paper proposes a method of preparing high-strength formed coke from woody biomass without binder. Chipped and pre-dried Japanese cedar was heat-treated in an inert atmosphere (i.e., torrefied) at 225–325°C (Tt), pulverized to sizes in three different ranges, molded into briquettes (in the form of thick disk with diameter/thickness ≈ 2.5) at temperature up to 200°C by applying mechanical pressure of 128 MPa. The torrefied/briquetted cedar (TBC) was then converted into coke by heating to 1 000°C in an inert atmosphere at normal pressure. This process sequence enabled to prepare coke having indirect tensile strength (St) of 8–32 MPa, which was much higher than that without torrefaction, below 5 MPa. The torrefaction greatly improved pulverizability of the cedar, which was further promoted by increasing Tt. St of TBC and that of coke both increased as the particle sizes of TBC decreased, but this explained only a minor part of significant effect of Tt on St of the coke. St was maximized at Tt = 275°C regardless of the degree of pulverization. The Tt effects on physicochemical properties of TBC and coke were investigated in detail. The difference in St of coke by Tt was mainly due to that in the increment of St along the carbonization at 500–1 000°C. Fracture surfaces of the coke had particular morphologies that had been inherited from the original honeycomb structure of the cedar.

    The large pore size of bare γ-CD-MOFs is not conducive to efficient CO2 sorption. This is due to the decrease in Van der Waals forces as the pore size increases, resulting in less favorable sorption behavior. This study aimed to optimize synthesis parameters to achieve optimum CO2 sorption and tune the porosity of the MOFs. The optimized K-CD MOF achieved a CO2 sorption of 4.1 mmol/g at 273 K.
    While applicant made progress in narrowing the larger pores by regulating synthesis parameters, applicant still believes that the much larger surface of K-CD MOF is yet to be explored.
