Abstract
A catalyst comprising palladium supported on a titania-alumina extrudate is disclosed. The extrudate comprises at least 80 wt % titania and 0.1 to 15 wt % alumina. A palladium catalyst prepared from the titania-alumina extrudate has significantly higher crush strength. Its catalytic performance in vinyl acetate production is improved.
