Abstract
Disclosed is a supported catalyst for the preparation of vinyl acetate monomer, a process for preparing the supported catalyst in tablet or pellet form, and a catalytic process for the manufacturing vinyl acetate using the supported catalyst. Specifically, it is shown that catalyst performance shows a strong dependence on the crush strength of the tableted or pelletized alumina support used in the process to make the catalyst, and that the crush strength of the catalyst is closely related to the porosity of the support. Catalyst activity and selectivity can be enhanced by tailoring the crush strength of the support.
