- Design of Biomass Pyrolysis Process for Production of Tar-free Active Biochar
- Production of metallurgical coke with high reactivity and strength from low rank carbonaceous solid
- Main purpose of this project is (1) to clarify characteristics of primary pyrolysis of pulverized coal and subsequent secondary reactions of nascent char and volatiles in CO2-containing atmosphere at temperature ranging from 1000 - 1300 degree-C and (2) to predict such characteristics by a model considering detailed chemical kinetics and mechanism.
- This work aims at experimental proof of biomass pyrolysis at temperature up to 500 C with full recycling of heavy oil and resulting selective production of light-oil, in other words, that of bio-oil that contains no or little evaporation residue.
- Development of advanced methods for converting low rank solid fuels into syngas, feedsctok for coke, binder and specialty chemicals by catalytic/noncatalytic reaction processes in sub
- Main purpose of this project is to develop a process that is applicable to conversion of various types of woody/herbaceous biomass resources into clean carbonized solids (biochar) and tar-free/H2-rich syngas by means of Pyrocoking method.
- This project aims to develop elemental technologies such as low temperature coal gasification, novel reactor systems with high-density/high-velocity particles circulation, chemical recuperation of heat from gas-turbines/SOFC, which are indispensable to the next-generation coal gasification combined cycle power generation.

Gasification of low-rank solid fuels with thermochemical energy recuperation for hydrogen production and power generation
J.-I. Hayashi S. Hosokai N. Sonoyama
Process Safety and Environmental Protection, Volume 84, Issue 6 B (2006), Pages 409-419 - Prof. Jun-ichiro Hayashi (Kyushu University) and Dr. Hiroyuki Uesugi (Biocoke Lab., Co. Ltd) have developed a technology for effectively converting biomass into tar-free gaseous and solid fuels, which is named Pyrocoking. The primary step of Pyrocoking is low-temperature rapid pyrolysis of biomass which produces the tar-free solid fuel (Biochar) and pyrolysis gas. The pyrolysis gas that contains tar vapor with a concentration as high as 900,000 mg/Nm3-dry is then reformed over a type of nanoporous soild such as Biochar, active alumina and nanoporous natural iron oxide. The tar vapor is quickly decomposed into light gases and carbon deposit (Biocoke). Biocoke can be used as smokeless clean solid fuel in ways similar to that for Biochar. Moreover, Biocoke-laden partially reduced iron ore is available as a type of raw material in local steel industry. Clean gas from the reforming contains tar with a concentration below 100 mg/Nm3-dry and directly available in IC engine cogeneration.
Thus, Pyrocoking produces Biomass-derived carbonized solids and power/heat simultaneously. - Formation of Carbon Nano-Capsules during Rapid Pyrolysis and Subsequent Steam Gasification of Brown Coal
