Nakaso, Jun Fukai, The feasibility of desorption on Zeolite-water pair using dry gas, 3rd International Conference on Science, Technology, and Interdisciplinary Research, IC-STAR 2017, 2018.04, The increase in temperature, reduction in partial pressure, reduction in concentration, purging with an inert fluid, and displacement with a more strongly adsorbing species are the basic things that occur in the practical method of desorption. In this study, dry gas at constant temperature and pressure was employed as the aid to reduce the partial pressure in the water desorption on the zeolite 13X. The objective of this study is to confirm the feasibility of desorption using dry gas experimentally and numerically. The implication of heat and mass transfers were numerically investigated to find the most influential. The results of numerical simulation agree with the experimental ones for the distribution of local temperature and average water adsorbed in the packed bed..

9. Jun FUKAI, Potential ability of zeolite to generate high-temperature vapor using waste heat, International Conference on Industrial Mechanical Electrical and Chemical Engineering 2017, 2017.09, In various material product industries, a large amount of high temperature steam as heat sources are produced from fossil fuel, then thermal energy retained by condensed water at lower than 100 ˚C are wasted. Thermal energies retained by exhaust gas at lower than 200 ˚C are also wasted. Effective utilization of waste heat is believed to be one of important issues to solve global problems of energy and environment. In this study, zeolite/water adsorption systems are developed to recover low-temperature waste heat (Fig. 1).
Firstly, an adsorption steam recovery system was developed to generate high temperature steam from unused hot water. The system used a new principle that adsorption heat of zeolite-water contact was effectively extracted. A bench-scaled system was constructed, demonstrating contentious generation of saturated steam at 150 ˚C from hot water at 80 ˚C. Energy conservation is expected by returning the generated steam to steam lines in the product processes. Secondly, it was demonstrated that superheat vapor at higher than 200 ˚C could be generated from saturated air at 120 ˚C using a laboratory scaled setup. The maximum temperature and the time variation of output temperature were successfully estimated using simple models. Lastly, the maximum temperatures were estimated when saturated air at the relative humidity 20 – 80 % was heated by the present system. Theoretically, air at higher than 200 ˚C was generated from saturated air at higher than 70 ˚C. It is consequently found that zeolite/water adsorption systems have potential ability to regenerate thermal energy of unused water and exhaust gas..

This system adopts a direct heat exchange method to the adsorption heat pump to increase heat transfer rate between adsorbent and heat transfer fluid. The heat pump system consists of two processes: steam generation process and regeneration process. In the steam generation process, water is directly introduced to the adsorbent. In the regeneration process, dry gas is introduced to the adsorbent. In this study, the performance of the system is numerically evaluated. The efficiency of the heat pump system is calculated by the ratio of enthalpy of product steam to input energy. To calculate the enthalpy of steam, mass of steam generated is estimated based on the progress of the regeneration process. Input energy of the heat pump system consists of the blower power to introduce dry gas and the thermal energy to heat dry gas. The effect of the operating condition on the performance of the steam generation process is studied. It is found there is the appropriate regeneration time to maximize the efficiency of the heat pump system..
