In this study, we detail a catalytic process for the conversion of fusel oil (FO), a by-product of ethanol production considered as waste, into valuable organic compounds, including aldehydes, alkenes, ketones, and alkylbenzenes spanning a carbon chain length from C to C. The reaction was carried out in a fixed bed flow reactor at atmospheric pressure, employing mixed metal oxides (MMO) derived from hydrotalcites (HTC) as catalysts. The HTC were readily synthesized by co-precipitation method involving Mg and Al, wherein 20 mol% Mg was substituted by M = Mn, Fe, Co, Ni, Cu, and Zn, and MMO obtained by HTC calcination. These catalysts offer cost-effectiveness compared to noble metal-containing ones while exhibiting remarkable activity in dehydrogenation, hydrogenation, and dehydration reactions pivotal for alcohol reactivity. The proposed methodology holds promise for large-scale industrial use and pioneers a fresh avenue for deriving value-added raw chemicals from a renewable carbon source.

从废物到化学原料：混合金属氧化物催化转化杂醇油

在这项研究中，我们详细介绍了将杂醇油（FO）（一种被视为废物的乙醇生产副产品）转化为有价值的有机化合物的催化过程，其中包括醛、烯烃、酮和烷基苯，其碳链长度为该反应在固定床流动反应器中在大气压下进行，使用衍生自水滑石（HTC）的混合金属氧化物（MMO）作为催化剂。 HTC很容易通过Mg和Al的共沉淀法合成，其中20 mol% Mg被M = Mn、Fe、Co、Ni、Cu和Zn取代，并通过HTC煅烧获得MMO。与含贵金属的催化剂相比，这些催化剂具有成本效益，同时在对醇反应性至关重要的脱氢、氢化和脱水反应中表现出显着的活性。所提出的方法有望大规模工业应用，并开创了从可再生碳源中获取增值化学原料的新途径。
