摘要：
To investigate the effects of different parameters temperature (220 ℃-300 ℃), reaction time (40 min-80 min), total solid content (10%-30%) on the yields and qualities of bio-oil, Response surface method is used for analysis of hydrothermal liquefaction treatment process for pig carcass to obtain indicators of bio-oil quality such as higher heating value, C recovery rate and N residual rate. The results showed that all the reaction conditions have effect on hydrothermal reaction process, most of which is temperature. The bio-oil with the most satisfied single index was obtained from different reaction conditions. To be more specific, the highest yield of bio-oil obtained is 76.94% (278 ℃, 64 min, 29%); the highest HHV obtained is 38.63 MJ/kg (290 ℃, 47 min, 30%); the highest C recovery rate obtained is 93.16% (260 ℃, 60 min, 10%), and the lowest N residual rate obtained is 15.52% (220 ℃, 40 min, 12%). The elemental analysis of bio-oil shows that hydrothermal liquefaction can effectively reduce the content of N and O in bio-oil and improve the quality of bio-oil, meanwhile, the FT-IR and TG/DTG analysis shows that the chemical composition of bio-oil is complex and mainly composed of organic compounds with large molecular weight and long carbon chain. © 2022, Solar Energy Periodical Office Co., Ltd.
