    摘要： The present invention provides a catalyst for aromatization of a long-carbon chain alkane and a preparation method thereof. In the present invention, a molecular sieve containing a BEA structure is taken as an active component and mixed with a carrier, and then the mixture is formed, dried and calcined to obtain the catalyst for aromatization of a long-carbon chain alkane. The active component is prepared by taking a Naβ molecular sieve as a raw material and modifying through the following steps of: first obtaining an Hβ molecular sieve through ammonium ion-exchange, and then conducting dealumination and silicon insertion treatment of the Hβ molecular sieve through first hydrothermal treatment; forming a mesoporous structure in a molecular sieve framework through second hydrothermal treatment; reducing the acidity of the catalyst by potassium ion exchange, and finally using metal modification to improve the capability of the catalyst for catalyzing the aromatization of the long-carbon chain alkane and enhancing the toluene selectivity. The catalyst provided by the present invention shows high stability in the aromatization of the long-chain alkane and has a service life up to 170 h or above and aromatic hydrocarbon selectivity up to 80%, and the selectivity to toluene in aromatic hydrocarbon products can reach 85.5%.

    摘要： 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.
