Catalyst, preparation method and use thereof

Abstract

Disclosed are a catalyst, as well as its preparation method and use thereof. The catalyst comprises a composite carrier and an active metal Ni loaded on the composite carrier; the composite carrier is formed by compounding a modifier and a natural mineral, wherein the modifier comprises zirconium and a rare earth metal; the natural mineral is one or more selected from diatomite, sepiolite, halloysite, attapulgite, vermiculite and molybdenite; the rare earth metal is one or more selected from yttrium, lanthanum, cerium, neodymium, samarium, europium, gadolinium and ytterbium. The catalyst of the present disclosure exhibits excellent structural stability, as well as high activity and high selectivity in the catalytic preparation of DMS. Particularly, the catalyst of the present disclosure exhibits excellent performance in the hydrogenation of DMM to produce DMS, which can effectively improve the selectivity to DMS and suppress the formation of GBL, BDO and THF.
