Nickel in the catalyst exists in a crystalline phase form, the catalyst is applicable to an aromatic hydrogenation reaction process and has high sulfur resistance and high hydrogenation activity, and the preparation method is simple to operate and easy to implement.

Description

technical field [0001] The invention relates to an aromatic hydrocarbon hydrogenation catalyst and a preparation method thereof. Background technique [0002] In the oil refining industry, the hydrogenation technology of aromatics has been paid more and more attention, mainly because the excessively high aromatics content in oil products has caused environmental problems. In order to reduce environmental pollution caused by incomplete combustion of aromatics, European and American countries have strictly limited the content of aromatics in fuel. Moreover, since there is a certain amount of sulfide in the oil, the catalyst will inevitably be affected by sulfur poisoning during the hydrogenation process. Therefore, it is currently a priority to develop aromatic hydrogenation catalysts with high sulfur resistance and high activity. One of the research hotspots. [0003] At present, aromatic hydrogenation catalysts mainly include traditional metal sulfidation catalysts and met...
