Thread Content

According to news from May 2, **information from the Intellectual Property Office shows that Sinopec Corporation and Sinopec Research Institute of Petroleum Chemistry Co., Ltd. have filed a patent application for a technology titled “Hydrogenation catalyst with high direct desulfurization selectivity, as well as methods for its preparation and use in hydrogenation processes”. Application publication number: CN121927645A; application number: CN202411513738.8. Publication date of the application: April 28, 2026; application date: October 28, 2024. Inventors: Li Huifeng, Li Zhenxing, Yang Qinghe, Zhu Jin, Zhang Rui. Patent agency: Beijing Yingchuang Jiayou Intellectual Property Agency Co., Ltd. Patent agent: Cheng Yuqing. Classification codes: B01J27/24, B01J35/61, B01J35/63, B01J35/64, C10G45/04, C10G45/08. The patent abstract indicates that the present invention relates to a hydrogenation catalyst with high direct desulfurization selectivity, as well as its preparation method and hydrogenation method; said hydrogenation catalyst comprises aluminum-modified mesoporous carbon material and active components loaded on said aluminum-modified mesoporous carbon material ； The metal elements of the active hydrogenation component include at least one group VIII metal element and at least one group VIB metal element ； Based on the total weight of the aluminum-modified mesoporous carbon material, the content of aluminum elements in this material is 0.1–8 weight%. The hydrogenation catalyst provided by the present invention uses aluminum-modified mesoporous carbon material as a carrier. This mesoporous carbon material features a regular pore structure, high porosity, and large specific surface area; acting as a catalyst carrier, it facilitates contact between the reactive molecules in the feedstock and the active centers. The loading of active components on this aluminum-modified mesoporous carbon material helps to improve the direct desulfurization selectivity of the hydrogenation catalyst.
