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.

Automated summary

The redox and acid-base properties of MgO-Al2O3 systems have been controlled by incorporating bifunctional additives of molybdates and tungstates during synthesis. Doping with Mo and W compounds enhances the activity of Mg-Al-oxide catalysts and the selectivity of 1-butanol formation in ethanol condensation process, attributed to the increased concentration of ethanol dehydrogenation and acetaldehyde aldol condensation sites.
