Disclosed is a supported catalyst for the preparation of vinyl acetate monomer (VAM), a process for preparing a catalyst comprising an extruded alumina support, and a catalytic process for the manufacturing vinyl acetate using the supported catalyst. Specifically, it is shown that for activated palladium-gold VAM catalysts prepared using extruded alumina supports, enhanced performance is demonstrated with increased pore volume of the support, and the gas hourly space velocity (GHSV, hr −1 ), which was found to significantly increase the space time yield as GHSV increased as compared to the non-extruded alumina supported catalysts. |
