Abstract: The conversion of hemicelluloses into energy and high-value chemicals by nonenzymatically catalyzing technology has the technical and economic feasibility. This article briefly introduces the recent developments in the research of the nonenzymatically catalyzing technology including hydrothermal conversion，microwave-assisted conversion，ionic liquid-catalyzed conversion and composite catalyst-catalyzed conversion for conversing hemicelluloses into bioenergy such as ethanol，butanediol and high-value chemicals such as furfural，acid，furan and so on. The nonenzymatically catalyzing technology overcomes the disadvantages of traditional enzymatically catalyzing technology such as the harsh reaction condition and the high enzyme cost，but some problems still exist，such as high requirement on equipment，no clear mechanism of reaction and low selectivity. Therefore，an in-depth investigation into the reaction mechanism and the improvement on reaction conditions needs to be considered in the future research.

摘要： 利用非酶工艺将半纤维素转化成能源及高附加值化学品具有技术上和经济上的可行性。本文详细介绍通过水热法、微波辅助法、离子液体以及复合型固体催化剂将半纤维素催化转化成乙醇、丁二醇等能源以及糠醛、酸、呋喃类高附加值化学品的国内外研究进展。非酶催化工艺克服传统酶催化反应条件苛刻、酶成本高等缺点，但对反应设备要求高，反应机理不明确，反应选择性低。因此，深入研究反应机理、改善反应条件成为今后研究方向。
