摘　　要：微波辅助下,以甲醇为溶剂的固体酸催化剂对稻壳热解油的催化加氢,采用GC/MS分析稻壳热解油催化前后正己烷萃取物。结果表明:稻壳生物油中的化合物十分复杂,主要成分为酮、酚、醛、酸和酯等含氧化合物;在固体酸催化下,酮和酚的含量大大降低;同时,稻壳热解油催化后正己烷的萃取物中的化合物种类也有所增加;微波辅助下,固体酸催化剂对稻壳热解油的催化加氢具有一定作用。The reaction of catalytic hydroconversion of pyrolyzed oil from rice hull over solid acid catalyst with methanol was conducted under microwave - assisted. The extractions of n - hexane was analyzed with GC/MS. The results showed that the extractions with nhexane of pyrolyzed oil were quite complex and there were many kinds of oxygen -containing organic compounds, which included ketones, phenols, aldehydes, acids, esters and so on. The contents of ketones and phenols decreased over solid acid catalyst. The kinds of components raised in the extractions of n - hexane with catalytic hydroconversion of pyrolyzed oil. Catalytic hydroconversion of pyrolyzed oil from rice hull over solid acid catalyst worked under microwave - assisted.
