摘要:
The invention relates to a shell catalyst for producing vinyl acetate monomer (VAM). Said shell catalyst comprises a porous catalyst support which is based on a natural phyllosilicate, especially on an acid-treated calcined bentonite, and which is loaded with Pd and Au. In order to provide a shell catalyst for use in the production of VAM which is characterized by a relatively high VAM selectivity and high activity, the catalyst support has a surface of less than 130 m2/g.
