High-selectivity catalyst for production of high-quality gasoline fractions from syngas and its preparation method
The invention relates to a catalyst for selective synthesis of high-quality gasoline fractions from syngas and the preparation method of the catalyst. This catalyst consists of cobalt, a promoter and molecular sieve, wherein cobalt is presented in an amount of 1-30%, the promoter is represented in an amount of 0.01-5% and the balance is molecular sieve based on the weight of the catalyst. This catalyst provides superior selectivity for C5-C11 isoparaffins and relatively lower selectivity for wax-type hydrocarbons with more than 20 carbon atoms. Thereof, this catalyst can be used for the synthesis of high-quality gasoline and is good at preventing catalyst coking. Besides, the invention provides a preparation method of the catalyst.
