  • The fast hydropyrolysis of Huolinhe lignite were carried out under pressure in a tubular reactor with a transporter for coal samples. The effect of H2 on CH4 evolution and crack of chemical bonds were analyzed. Under pressure fast hydropyrolysis conditions, CH4 yield was higher under H2 atmosphere than that under N2 atmosphere, and increased with increasing temperature and pressure. Compared with N2 atmosphere, the yield of CH4 increased by 72.5% under 50% H2 atmosphere at 900 ℃ and 1.0 MPa. H2 or H· free radical induced the cracks of aromatic rings, side chains, ether linkages and aliphatic chains in the char, which could promote the coal pyrolysis. The increased yield of CH4 was mainly due to the external donor H. Below 700 ℃, the action of H2 with active groups in coal structure affected the pyrolysis of coal; above 700 ℃, hydrogenation of char promoted coal pyrolysis, leading to an increase in CH4 yield.
