| 简介 | A shell catalyst for producing vinyl acetate monomer (VAM), comprising an oxidic porous catalyst support, formed as a shaped body, with an outer shell in which metallic Pd and Au are contained. To provide a shell catalyst for producing VAM which has a relatively high activity and can be obtained at relatively low cost, the catalyst support is doped with at least one oxide of an element selected from the group consisting of Li, P, Ca, V, Cr, Mn, Fe, Sr, Nb, Ta, W, La and the rare-earth metals. | ||
