Investigation on Initial Stage of Rapid Pyrolysis at High Pressure Using Taiheyo Coal in Dense Phase

Rapid pyrolysis of a Japanese sub-bituminous coal was examined in a laboratory-scale batch-type reactor. The pyrolysis reaction was strongly affected by the coal/gas ratio and was retarded at the initial stage at high ratios. Major products identified included methane, hydrogen, carbon oxides, and b...

Summary:Rapid pyrolysis of a Japanese sub-bituminous coal was examined in a laboratory-scale batch-type reactor. The pyrolysis reaction was strongly affected by the coal/gas ratio and was retarded at the initial stage at high ratios. Major products identified included methane, hydrogen, carbon oxides, and benzene, while ethylene and toluene were representative of intermediate products. Heat capacity of atmospheric gas exerted less influence on pyrolysis while heat conductivity of atmospheric gas and mixing conditions markedly affected the process.
