Abstract (en)
[origin: WO2008145392A2] The invention relates to a shell catalyst for producing vinyl acetate monomer. Said shell catalyst comprises an oxidic porous catalyst support having an outer shell that contains metallic Pd and Au, the framework of the porous catalyst support containing hafnium oxide moieties. The shell catalyst according to the invention is suitable for the production of VAM and is characterized by a relatively high activity and VAM selectivity and preserves this activity and selectivity over a relatively long service life. The invention also relates to a method for producing the shell catalyst.
