摘要
在合成过程中,通过引入钼酸盐和钨酸盐双功能添加剂,对氧化镁-氧化铝体系的氧化还原和酸碱性质进行了调控。Mo和W化合物的掺杂导致mg - al -氧化物催化剂的活性增加,乙醇缩合过程中1-丁醇生成的选择性增加,因为乙醇脱氢和乙醛缩合的位点浓度增加。
Effect of Modifying Additives of Molybdenum and Tungsten Compounds on the Catalytic Properties of MgO-Al2O3 in the Process of Gas-Phase Conversion of Ethanol Into 1-Butanol
The regulation of redox and acid–base properties of MgO-Al2O3 systems has been carried out during the synthesis by introducing bifunctional additives of molybdate and tungstate ions. Doping with Mo and W compounds leads to an increase in the activity of Mg-Al-oxide catalysts and the selectivity of 1-butanol formation in the ethanol condensation process due to an increase in the concentration of the sites of ethanol dehydrogenation and acetaldehyde aldol condensation.
