CATALYST FOR CONVERTING SYNGAS INTO HIGH-GRADE GASOLINE FRACTION WITH HIGH SELECTIVITY AND PREPARATION METHOD THEREOF

摘要

A catalyst for converting syngas into high-grade gasoline fraction with high selectivity and a preparation method thereof are disclosed. The catalyst consists of 1-30% metal cobalt, 0.01-5% promoter element and the balance of molecular sieve, based on the weight of the catalyst. The catalyst exhibits high selectivity to C5-C11 isoparaffin and very low selectivity to C20 + waxy hydrocarbons. Therefore, the catalyst can be used for preparing high-grade gasoline fuel, and can prevent or significantly reduce carbon deposition on the catalyst. Furthermore, a preparation method for the catalyst is also provided.
