  • Patent number: 10399060
    Abstract: 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.

    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.
