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.
