Abstract

A gaseous starting method for a hydrocracker containing a hydrogenation catalyst with second type active centers is provided. The method utilizes a plurality of hydrogen sulfide containing gases in industrial equipment to pre-protect the catalyst before sulfuration, and a formed gas protective film can completely avoid decomposition of auxiliary agents in the catalyst, thus avoiding problems which are activity loss and increased material consumption in a starting process, saving energy and greatly improving using activity of the catalyst.

Description

technical field

[0001] The invention relates to a start-up sulfidation method of a hydrogenation catalyst, especially for a catalyst containing a second type of active center, mainly by using various industrial gases containing hydrogen sulfide to pre-protect the catalyst so that it can be started in a dry process , to achieve the purpose of improving catalyst activity, and is suitable for the sulfuration process of various second-type active center catalysts. Background technique

[0002] At present, due to the increasingly heavy crude oil in the world and the strict requirements of environmental protection regulations, the quality of raw materials processed by hydrogenation devices is deteriorating year by year. Various impurities contained in raw materials, including metals, The content of reactants such as sulfur and nitrogen is on the rise. In this harsh environment, catalyst developers in various countries have regarded the renewal and progress of catalyst activity as ...
