Abstract

The invention belongs to the technical field of petroleum processing, and specifically relates to a preparation method of a Fe based suspended bed hydro-cracking catalyst. FeCl3.6H2O and Fe2(SO4)3.xH2O are taken as the inorganic iron source; cheap sesbania cannabina powder is taken as a template; and a sol-gel method and a hydrothermal method are adopted to prepare a mesoporous gamma-Fe2O3 catalyst, which has a high specific surface area and is suitable for the hydro-cracking reactions carried out in a low quality residual oil suspended bed. The synthesis technology is simple, the synthesis period is short, the catalyst is environmentally friendly and pollution free, and the cost is low. The prepared mesoporous gamma-Fe2O3 catalyst has a good performance in hydro-cracking reactions carriedout in a residual oil suspended bed.

Description

technical field [0001] The present invention relates to the preparation of Fe-based suspended bed hydrocracking catalyst, in particular to a mesoporous γ-Fe 2 o 3 Catalyst preparation method. Background technique [0002] With the continuous development of the national economy, the country's demand for light fuel oil such as gasoline, diesel and aviation kerosene continues to increase, while the trend of heavy and inferior crude oil continues to intensify, and environmental protection regulations have increasingly stringent requirements for the quality of refined oil , the contradiction between the heavy and inferior crude oil and the light and clean products is intensifying, which poses a severe challenge to the sustainable development of the oil refining industry. Efficient conversion of heavy oil is one of the main means to improve crude oil utilization and ensure energy supply. Heavy oil is characterized by large molecular weight, complex composition, high content of ...
