摘要

以离子液体1-丁基-3-甲基咪唑氯(IL)为添加剂、考察5A-Ca型分子筛、HNO3及FeCl3等催化剂对甲基纤维素(MC)微波裂解过程的影响。实验研究了IL用量、微波功率、作用时间及催化剂对MC裂解的影响，并通过GC-MS联用仪研究了微波裂解液体产物分布的变化。结果表明，不同催化剂导致了不同的液体产物分布，其中5A-Ca型分子筛催化剂可促进小分子物质的形成，同时使生物质油中的含氧量从37.43%降低到了34.82%；HNO3催化剂促进了醋酸甲酯、正丁醇及苯甲酸甲酯的生成；FeCl3作为催化剂时，促进了糠醛及5-甲基糠醛的生成。通过比较常规热解与微波裂解，发现微波裂解能在较短的时间内得到高的生物质油产率。

Abstract

Ionic liquid 1-butyl-3-methylimidazolium chloride（IL)was used as an additive for methyl cellulose（MC)pyrolysis under microwave irradiation.The effects of reaction conditions

including IL amount

microwave power and reaction time and catalysts FeCl3

HNO3 and 5A-Ca molecular sieve on MC pyrolysis were studied.The results show that components in bio-oils obtained vary with the catalysts. 5A-Ca catalyst could promote formation of small molecules and reduce the oxygen content in product from 37.43% to 34.82%. HNO3 catalyst could do that of methyl acetate

1-butanol and methyl benzoate. Furfural and 5-methyl furfural are found for FeCl3 catalyst.Comparing with conventional pyrolysis

the microwave pyrolysis with IL as additive but without catalysts could have higher yields of bio-oil in a short time.
