摘要
进行了稻草在离子液体氯代1-烯丙基-3-甲基咪唑([AMIM]Cl)中的热解反应,考察了反应温度、稻草与离子液体的质量比及反应时间对产物产量的影响,得到较佳工艺条件是:稻草与离子液体质量比为0.4,热解温度240℃,反应时间为30 min.生物油收率均在28%～30%.对热解得到的产物生物油进行GC-MS分析显示:其成分复杂,生物油中有醇、酚、醚、酯及芳香烃类物质的存在.离子液体可以回收利用.
Abstract： In this paper, the pyrolysis reaction of straw in the ionic liquid chloro-l-allyl-3-methyl imidazole （[ AMIM] CI） was mainly studied. The effects of temperature, straw and ionic liquid mass ratio and reaction time on product yield were investigated, and optimal process conditions were got as following： straw and ionic liquid mass ratio was 0.4, the thermal decomposition temperature was 230 ℃, and reaction time was 30 min. The yield of bio-oil was 28% -30%. The product of pyrolysis obtained by experiment using GC-MS was analyzed, and the results showed that the composition of bio-oil was complex. There were alcohol, phenols, ethers, esters and aromatic substances in bio-oil. Ionic liquid can be recycled.
