摘要：

It is shown that promotion of gamma-Al2O3 with zirconium, cobalt, boron, lanthanum, and cerium oxides strongly affects its catalytic activity and stability in vapor-phase dehydration of glycerol into acrolein. Modification of gamma-aluminum oxide with acid oxides impairs the stability and activity of the catalyst. Introduction of lanthanum and cerium oxides into the structure of gamma-Al2O3 leads to a decrease in the number of strong acid centers, which diminishes the activity of the catalytic system and improves its stability.
