Abstract

The invention discloses a microspherical catalyst as well as a preparation method and an application thereof. The preparation method comprises the following steps: 1) mixing and stirring zeolite powder and ethyl alcohol so as to obtain slurry; 2) sequentially drying, forming, setting and sintering the slurry obtained in the step 1), thereby obtaining zeolite catalyst microspheres; and 3) impregnating the zeolite catalyst microspheres obtained in the step 2) into a metal impregnation liquid, and then drying the impregnated zeolite catalyst microspheres so as to obtain the microspherical catalyst. The preparation method is simple and convenient to operate; the prepared microspherical catalyst has high cracking performance, high desulfuration, denitrification and deoxygenation performance, high hydrogenation performance, high demetalization performance and high coke adsorption performance, and can be widely applied to heavy oil slurry bed hydrocracking process.

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...
