Abstract

The invention relates to a Fischer-Tropsch synthesis catalyst comprising composite molecular sieve, and a preparation method and an application thereof. The catalyst contains an active metal component selected from iron and / or cobalt, and a composite molecular sieve. The catalyst selectively contains a carrier of a heat-resistant inorganic oxide substrate. According to the catalyst as a standard, the content of the composite molecular sieve is 1-60wt%, and the content of the heat-resistant inorganic oxide substrate is 0-80%. According to the oxide, the content of the active metal component is 2-50%. The composite molecular sieve is a mixture comprising at least one non-zeolite molecular sieve and at least one zeolite molecular sieve, wherein a weight ratio of the non-zeolite molecular sieve to the zeolite molecular sieve is 0.1-90. The catalyst has high Fischer-Tropsch synthesis activity and selectivity, and has a selective cracking capacity upon heavy hydrocarbon in Fischer-Tropsch synthesis product. The catalyst can be directly used in Fischer-Tropsch synthesis reactions for producing clean liquid hydrocarbon products.

Description

field of invention [0001] The invention relates to a Fischer-Tropsch synthesis catalyst, its preparation and its application. Background technique [0002] Fischer-Tropsch synthesis (FTS, FT synthesis) refers to synthesis gas (CO+H 2 ) into hydrocarbons on a catalyst, the products include alkanes and alkenes, and by-product CO 2 , H 2 O and organic oxygen-containing compounds such as alcohols, aldehydes, acids, ketones and esters. The products can be processed to obtain high-quality liquid fuels, such as gasoline, diesel and aviation kerosene. It has been more than 80 years since the discovery of FT synthesis. South Africa began to use FT synthesis technology industrially in the 1950s and has been developing until now. [0003] Petroleum resources are depleting day by day, prices fluctuate at high levels, and people are increasingly active in finding alternative resources; while the proven reserves of coal and natural gas continue to increase, the research in the field of...
