中文摘要：

随着石化资源的不断枯竭和石油价格的飞涨，以化石资源为原料的化学品生产受到了严峻的挑战。可再生的生物质作为化石资源的替代原料进行化学品的生产可以减少对石化资源的依赖，对于人类可持续发展战略具有重要意义。生物质发酵得到生物乙醇，然后以乙醇为平台通过催化转化的方法得到下游化学品，是从生物质得到化学品的重要方法。本文综述了以乙醇转化成其它下游化学品的催化过程，着重介绍和评价了乙醇催化制氢、催化脱水制乙烯以及其它化学品开发的发展状况。最后讨论了当前亟待解决的问题和对策。

英文摘要：

With the depletion of fossil fuel resources and the soaring prices of crude oil, the production of petrochemicals from fossil fuel as raw materials has been a severe challenge. Renewable biomass as a substitute for crude oil to produce petrochemicals can reduce the reliance on fossil fuel resources, so it is of great significance to sustainable development. With bio-ethanol, produced by fermentation ofbiomass, as platform, production of downstream products through catalytic conversion is an important means. This paper reviews the catalytic process to convert ethanol into downstream chemicals, focuses on the development of the catalyst to produce main downstream chemicals, such as hydrogen, ethylene, acetaldehyde and acetic acid. In the end, key urgent problems are addressed and perspectives are discussed.
