Abstract
The present invention provides a method for preparing gasoline and aromatics by using Fischer-Tropsch synthesis exhaust. The method includes conducting an olefin conversion reaction on Fischer-Tropsch synthesis exhaust under the action of a first molecular sieve catalyst. A first refrigeration or cooling is conducted on an obtained product to obtain ultralow sulfur-containing gasoline and first-stage reaction gas. An alkaline aromatization reaction is conducted on the first-stage reaction gas under the action of a second molecular sieve catalyst. A second refrigeration or cooling is conducted on an obtained product to obtain aromatics. After the olefin conversion reaction, a gasoline component is separated and residual alkanes enter a second-stage fluidized bed reactor for the alkane aromatization reaction to produce aromatics. The present invention implements step conversion of different components in the Fischer-Tropsch exhaust, and has advantages of high reaction yield, easy catalyst regeneration and amplification, and the like.
