Abstract

The invention discloses a microsphere catalyst and its preparation method and application. The preparation method includes the following steps: 1) mixing zeolite powder and ethanol for stirring to obtain a slurry; 2) sequentially drying, shaping, finalizing and sintering the slurry obtained in step 2) to obtain zeolite catalyst microspheres ; 3) Dip the zeolite catalyst microspheres in step 2) into the metal impregnation liquid, and then dry the impregnated zeolite catalyst microspheres to obtain the microsphere catalyst. The preparation method is simple and easy to operate. The prepared catalyst microspheres have high cracking performance, desulfurization, denitrification, deoxygenation performance, high hydrogenation performance, demetallization performance, and coke adsorption performance, and can be widely used in heavy oil suspended bed hydrogenation processes. middle.

Description

technical field [0001] The invention belongs to the field of catalyst preparation in the hydrogenation process of heavy oil suspended bed, in particular to a microsphere catalyst and its preparation method and application, in particular to a microsphere catalyst used in the hydrogenation process of heavy oil suspension bed and its preparation method and application . Background technique [0002] With the rapid development of our country's economy, the consumption of oil has increased rapidly. my country's energy pattern is short of oil, low in gas, and rich in coal. From the national energy strategy, oil and gas are needed. Therefore, the lightening of heavy oil has attracted more and more attention. Among them, the suspended bed process of heavy oil is one of the most effective processes for lightening heavy oil. In the process of lightening heavy oil, various processing Use of Hydrogen Catalysts. [0003] Common residual oil hydrogenation catalysts use alumina as the c...
