Abstract: Using Chinese fir sawdust as raw material, the experiments of biomass vacuum pyrolysis for production of bio-oil were carried out. The effects of pyrolysis parameters such as pyrolysis temperature, system pressure, holding time of final pyrolysis temperature and heating rate on the yield of bio-oil were investigated. The effects of pyrolysis parameters on chemical components of bio-oil were analyzed by GC-MS. Under final pyrolysis temperature set at 500℃, system pressure at 20 kPa, holding time of the final pyrolysis temperature for 60 min and heating rate of 60℃/min, the maximum yield of bio-oil reached up to 67%.
Key words: biomass, Chinese fir sawdust, vacuum pyrolysis, bio-oil, GC/MS analysis
摘要: 以杉木屑为原料,进行了真空热解制备生物油的实验研究. 考察了体系压力、热解终温、终温保持时间及升温速率等热解参数对生物油产率、生物油组分及其相对含量的影响. 结果表明,热解终温为500℃、体系压力为20 kPa、热解终温保持时间为60 min、升温速率为60℃/min的条件有利于杉木屑真空热解制备生物油的生产,其产率达67%以上. 真空热解过程中,慢速热解可得到较高的生物油产率.
