Abstract

The invention relates to the field of catalysts, in particular relates to a preparation method and use of a hydrocracking catalyst. The preparation method of the hydrocracking catalyst comprises the following steps: (1) performing acidification treatment, washing treatment and drying treatment on retort biomass carbon to obtain a biomass carbon carrier; and (2) fully mixing and grinding the biomass carbon carrier and a catalyst active component to obtain the hydrocracking catalyst. A solid-solid method is used, washing, drying, roasting and other cumbersome procedures are reduced, the operation process is simple, and the production is easy to scale up. At the same time, the active component of the catalyst prepared by the process is uniformly loaded, the catalytic activity is high, the gasyield is low, and the biomass conversion rate is high, the active component of the catalyst has the functions of hydrogen activation and deoxygenation, and the hydrocracking catalyst effectively inhibits coking reaction, improves product oil quality, and can be applied to hydrocracking reactions of various fluidized reaction beds.

Description

technical field [0001] The invention belongs to the field of catalysts, and in particular relates to a preparation method and application of a hydrocracking catalyst. Background technique [0002] With the continuous expansion of industrial production scale, the demand for energy continues to rise, and the supply of non-renewable energy such as coal, oil, and natural gas is seriously insufficient; in addition, the extensive use of fossil energy has also brought serious impact on the global environment. . Therefore, the development and utilization of renewable biomass resources has become a hot spot of global concern. [0003] The global biomass reserves are abundant, and it is a clean renewable resource. The development and utilization of renewable biomass resources instead of non-renewable resources is currently considered to be an effective way to solve the shortage of non-renewable resources. Biomass oil obtained by pyrolysis of biomass is a mixture of water and complex...
