Abstract

The invention provides a preparation method of a hydrogenation catalyst. According to the method, part of an active metal component and an organic acid complexing agent are introduced in a supporter forming process, a supporter is formed by a certain baking process, and then a subsequent active metal impregnation step is performed to obtain the hydrogenation catalyst. The hydrogenation catalyst provided by the invention has active metal uniformly dispersed, is simple and easy to prepare and is especially suitable for ultra-deep hydrodesulfurization reaction of diesel oil.

Description

technical field

[0001] The invention relates to a preparation method of a hydrogenation catalyst, in particular to a preparation method suitable for an ultra-deep hydrodesulfurization catalyst for diesel oil. Background technique

[0002] As the world's crude oil production is becoming more and more heavy, and the demand for clean oil products is increasing today, in the process of producing clean oil products, the hydrodesulfurization process technology of petroleum fractions plays an increasingly important role. The high activity requirements of hydrogen catalysts are also increasing.

[0003] For ultra-deep hydrodesulfurization catalysts, the type II active center theory of Co-Mo-S and Ni-Mo-S has been widely accepted by major research and development institutions, and new high-activity hydrotreating catalysts have been developed based on this. The main improvement schemes include the choice of carrier, the application of additives, the complexation of impregnation solut...
