Paper Title:
Product distribution during Datong Coal Pyrolysis and Hydropyrolysis
  Abstract

Pyrolysis and hydropyrolysis of Chinese Datong coal was carried out at temperature from 350 to 650°C,under pressure of 2Mpa in a fix-bed reactor. The product distribution was determined, and gas evolution of coal pyrolysis and hydropyrolysis was also studied. The experimental results shows that coal conversion and water yield increase with temperature increasing during both pyrolysis and hydropyrolysis; tar yield increase during hydropyrolysis with temperature from 350 to 650°C, but the highest tar yield during pyrolysis is at temperature of 550°C. At high temperature area, CO、CH4 and C2+ has higher yield in hydropyroly than that in pyrolysis. The products distribution of pyrolysis and hydropyrolysis showed that the effect of H2 on coal thermal conversion only occurs at high temperature area.
