摘要：Non-catalytic hydropyrolysis of pinewood and its components was carried out using a two-stage reactor. The main aim of this work is to investigate the hydrodeoxygenation and hydrogenation of volatile matter in the post hydrocracking reactor for oriented production of gaseous and light aromatic hydrocarbons. A portion of volatile matter, which evolved from hemicellulose, neutral extractives and lignin below 275 degrees C, was found to be thoroughly hydrodeoxygenated preventing the release of CO2 and CO. Increasing hydrocracking temperature from 600 degrees C to 750 degrees C and pressure from 1.0 MPa to 5.0 MPa strongly facilitated the hydrogenation reactions to target products. The summed yield of CH4 and C2H6 (dry biomass basis) reached up to 33.2% at a hydrocracking temperature of 750 degrees C and 5.0 MPa, with a concomitant 5.1% yield of BTX. All components in pinewood significantly contributed to the production of CH4 and BTX by hydropyrolysis, differing from the case of pyrolysis.
