Abstract:
A catalyst includes a support, where the support includes an external surface, about 60 wt % to about 99 wt % silica, and about 1.0 wt % to about 5.0 wt % alumina. A catalytic layer is disposed within the support adjacent to the external surface, where the catalytic layer further includes Pd, Au, and potassium acetate (KOAc). In the catalyst, (a) the KOAc is from about 60 kg/m3 to about 150 kg/m3 of the catalyst; or (b) the catalytic layer has an average thickness from about 50 μm to about 150 μm; or (c) both (a) and (b). The catalyst also possesses a Brunauer-Emmett-Teller surface area of about 130 m2/g to about 300 m2/g and a geometric surface area per packed bed volume from about 550 m2/m3 to about 1500 m2/m3. The catalyst is highly active for the synthesis of vinyl acetate monomer and exhibits a high selectivity for vinyl acetate monomer.
