Abstract
A catalyst for the synthesis of methyl mercaptan from hydrogen sulfide and methanol, as well as a process for preparing the catalyst. The catalyst contains active aluminum oxide on which 15% to 40% by weight cesium tungstate is deposited as the activator. The activator, cesium tungstate, gives an unexpected increase in activity and selectivity as compared with potassium tungstate, which is used exclusively at the present state of the art.
Claims12
A catalyst composition comprising aluminum oxide particles containing cesium tungstate as the activator, wherein the cesium tungstate is present in a proportion of from more than 15% to 40% by weight, based on the total weight of the finished catalyst.
