摘要：

The bio-oil produced by fast co-pyrolysis of municipal sewage sludge and typical wooden biomass (pine sawdust and poplar sawdust) in a horizontal tubular furnace was studied. The yield and composition of bio-oil generated during co-pyrolysis process were further analyzed. The results show that the bio-oil has similar components with the two biomasses, which mainly contains acids, esters, phenols, and nitrogen compounds. Higher amount of biomass can reduce sulfur content in the bio-oil but promotes the accumulation of nitrogen. Synergistic effect on bio-oil yield is calculated, and the result indicates that synergistic effect has negative correlation with high sawdust addition rate. The greatest synergistic effect on the bio-oil yield, which is 12.12%, is observed when 10% poplar sawdust is added. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
