Abstract Ethanol conversion to butanol was investigated over mixed oxides derived from hydrotalcites modified with copper, palladium or indium. The reaction was carried out in the 403–573 K temperature range using stainless steel reactors. The presence of indium or palladium in the catalyst influences the temperature of reaction so that it was possible obtain butanol at temperature as low as 423 K. This is in line with the fact that the addition of metals with high hydrogen-transfer capacity makes faster all steps of the reaction with great energy saving. The best selectivity to butanol (65%) was achieved using In-CuMgAl catalysts with 3% of ethanol conversion at a temperature as low as 443 K.

在钯 (II) 和铟 (III) 改性的 CuMgAl 混合氧化物上从乙醇合成丁醇

摘要 研究了用铜、钯或铟改性的水滑石衍生的混合氧化物将乙醇转化为丁醇。该反应使用不锈钢反应器在 403-573 K 温度范围内进行。催化剂中铟或钯的存在会影响反应温度，因此有可能在低至 423 K 的温度下获得丁醇。 这与添加具有高氢转移能力的金属使所有反应更快的事实一致。非常节能的反应步骤。使用 In-CuMgAl 催化剂在低至 443 K 的温度下以 3% 的乙醇转化率实现了对丁醇的最佳选择性 (65%)。
