Abstract
The conversion of ethanol to 1,3-butadiene(1,3-BD)has beeninvestigated over ZrO2-and ZnO-containing magnesia silicaoxides prepared by aco-precipitation method at different Mg-to-Si molar ratios. The effect of reactiontemperature and etha-nol flow rate was investigated. The catalyst acidity was modi-fied throughthe addition of alkali metals (Na, Kand Li)tothefinal materials.Catalysts were characterised by nitrogen physi-sorptionanalysis, X-ray diffraction, scanning electron microsco-py with energy dispersive X-ray,temperature-programmed de-sorptionofammonia, infraredspectroscopy and29Si/(7Li)NMRspectroscopy.The catalytic results showed that the controlledreduction of catalyst acidity allows ethanol dehydration to besuppressed, whilst increasing 1,3-BD selectivity.The bestcata-lytic performance achieved72mol%for the combined 1,3-BDand acetaldehyde selectivity.
