本发明涉及一种醋酸仲丁酯加氢生产仲丁醇联产乙醇的方法,主要解决现有技术中能耗较高、氢气消耗较大的问题。本发明通过采用一种醋酸仲丁酯加氢生产仲丁醇联产乙醇的方法,包括以下步骤:(1)氢气和汽化的醋酸仲丁酯在反应器中与含铜催化剂接触,进行加氢反应得到含仲丁醇和乙醇物流,经两级气液分离获得粗仲丁醇和乙醇混合物;(2)粗
The invention relates to a method for producing sec-butanol co-production ethanol by hydrogenation of sec-butyl acetate, which mainly solves the problem of high energy consumption and large hydrogen consumption in the prior art. The present invention provides a process for producing sec-butanol co-production ethanol by hydrogenation of sec-butyl acetate, which comprises the following steps: (1) contacting hydrogen and vaporized sec-butyl acetate with a copper-containing catalyst in a reactor for hydrogenation The reaction to obtain sec-butanol and ethanol stream, obtained by two-stage gas-liquid separation of crude sec-butanol and ethanol mixture; (2) crude
