Problems solved by technology

[0016] However, the current Fischer-Tropsch synthesis catalysts still have the following problems: due to the FT reaction, CH 4 and other lower hydrocarbons, CO 2 The formation of such gas components is promoted, and the gasoline yield is reduced; or it cannot adapt to the most suitable reaction problem, or the activity of the catalyst is low and easy to deactivate, the stability is poor, and the gasoline fraction yield is low at a higher reaction temperature at home, etc. Stablize

Embodiment 1

[0062] Preparation of composite carrier 10g: Add deionized water into the reaction kettle, stir and add attapulgite, stir and mix evenly, and prepare slurry A; use magnesium nitrate and aluminum nitrate as precursors, and use citric acid or ethylene glycol as complex agent, made into a solution and mixed and stirred evenly, then the water evaporated, the solution changed from a transparent sol to a viscous gel, and finally dried at 100-150°C for 1-12 hours, and baked at 200-400°C for 1-4 hours. After roasting, the magnesium aluminum spinel metal oxide MgAl2O4 is obtained; the magnesium aluminum spinel oxide is added to the slurry A, the temperature is controlled, the stirring is continued and the mixing is uniform, and the slurry B is obtained by ultrasonic treatment; the slurry B The attapulgite and spinel oxide composite carrier of the catalyst is obtained by roasting after spray drying and shaping;

Description

technical field [0001] The present invention relates to a catalyst composition used in the production of hydrocarbons from a mixed gas mainly composed of hydrogen and carbon monoxide (hereinafter referred to as "synthesis gas") by the Fischer-Tropsch (FT) reaction, and the production of hydrocarbons from the above-mentioned synthesis gas by the FT reaction. hydrocarbon method. More specifically, it relates to a method for producing hydrocarbons characterized by using a catalyst composition comprising a FT-active metal supported on a composite carrier, and using the above-mentioned FT synthesis catalyst. Background technique [0002] As methods for synthesizing hydrocarbons from synthesis gas, Fischer-Tropsch reaction, methanol synthesis reaction and the like are well known. The synthesis technology in indirect coal liquefaction was first discovered by German scientists Frans Fischer and Hans Tropsch in 1923 and named after their first letter, F-T, referred to as F-T synthes...
