According to information from the Intellectual Property Office as of June 13, 2025, Sinopec Corporation, Sinopec Ningbo New Materials Research Institute Co., Ltd., Dalian University of Technology, and Sinopec Zhenhai Refining & Chemical Co., Ltd. have filed a patent application titled “Catalyst and Its Preparation Method and Application”, with the publication number CN120132854A; the application was submitted in December 2023. The patent abstract indicates that the present invention relates to the field of catalysts, and discloses a catalyst, as well as its preparation method and applications. The catalyst comprises a modified carrier and an active metal loaded on the modified carrier, wherein the modified carrier contains a carrier and a modified metal element ； Among them, the modified metal element is selected from iron and/or ruthenium, and the active metal is selected from at least one of lithium, sodium, potassium, and calcium. In this catalyst, the carrier is modified using modified metallic elements, resulting in highly dispersed sites on the surface of the modified carrier. This enables the active metal to combine with the modified metal during the mechanochemical preparation process, allowing the active metal to be fully dispersed and effective active sites to be exposed. As a result, the catalyst exhibits high activity and selectivity ； The preparation method of the catalyst provided by the present invention simplifies the operating conditions and process flow, features mild conditions, and avoids the explosion risk associated with high temperatures.
