Low-cost sulfur-tolerant shift catalyst and preparation method thereof

The invention belongs to the technical field of sulfur-tolerant shift, and relates to a low-cost sulfur-tolerant shift catalyst and a preparation method thereof. The catalyst is prepared by performing roasting pretreatment on attapulgite clay for obtaining a carrier, then loading active components such as Mo, Co and Mn, and performing kneading, molding, air drying and roasting. The catalyst comprises the following chemical compositions: in percent by mass, 0.5-1% of CoO, 1-2% of MoO, 1-2% of MnO, and the balance attapulgite clay subjected to roasting pretreatment. According to the technical scheme, the purpose of reducing catalyst production cost is realized, the catalyst is good in stability, has the shit, dust-resisting and position-removing functions, helps to provide a relatively effective utilization approach for wide-source low-cost attapulgite clay, and has good economic benefit and application prospect.
