Abstract

In order to explore the pyrolysis law and product distribution of waste biomass, take in different materials （pine, sludge and domestic garbage） as the research object, the change law of pyrolysis performance of different biomass under continuous heating was studied by using first-order fixed-bed reaction system. The results show that high temperature promoted the pyrolysis of biomass, increased the yield of pyrolysis gas and reduced the tar yield. Especially, the pyrolysis process of pine was significantly affected by the change of temperature. After high temperature pyrolysis, the tar compound distribution of pine, sludge and domestic garbage had obviously different, in which there was no acid in the pyrolysis oil of pine. The proportion of phenols and alcohols increased significantly, while the proportion of ketones changed little. Furthermore, the feasibility of preparing high value gas by biomass pyrolysis was demonstrated through different indexes. It is concluded that biomass pyrolysis gas has good synergism and good application prospect, which is an important direction of high value utilization of biomass and an important way to produce green hydrogen. It lays a solid foundation for the preparation and utilization of hydrogen rich-gas by catalytic pyrolysis of biomass.
