Influence of the Nature of Rare Earth Elements (Y, La, Ce) on Physicochemical and Catalytic Properties of Mg-Al Oxide System in the Vapor-Phase Conversion of Ethanol Into 1-Butanol
摘要
The results of study on the influence of rare earth elements (Y, La, Ce) on physicochemical characteristics and catalytic properties of Mg-Al oxide system in the vapor phase condensation process of ethanol with the obtaining of 1-butanol are presented. The Mg-Al-Y-oxide catalyst is established to have the highest selectivity for the target product 1-butanol, as well as the stability of operation over time. The positive effect of yttrium consists in the formation of additional acidic and basic sites on the catalyst surface.
