According to data from the Tianyancha app, Sinopec (600028) has newly obtained an invention patent grant. The title of the patent is “A fluidized bed heavy oil hydrogenation catalyst and its preparation method and application”, with the patent application number CN202211601966.1; the grant date is August 5, 2025. Patent Abstract: The present invention discloses a fluidized bed heavy oil hydrogenation catalyst, as well as its preparation method and applications. The fluidized bed heavy oil hydrogenation catalyst comprises an active metal component, a co-active metal component, optional additives, and a carrier. The preparation method includes the following steps: (1) Balling diaspore powder to obtain carrier precursor A ； (2) Mix organic polymer A, nitrogen-containing weak base compounds, and diaspore powder to obtain a mixture ； (3) Prepare carrier precursor B by combining carrier precursor A with the mixture material and an aqueous solution of the heat-treated organic polymer B ； (4) Carrier precursor B is subjected to low-temperature heat treatment to yield carrier precursor C ； (5) The carrier precursor C is mixed with a soluble zinc salt solution, dried, and calcined in an inert atmosphere to obtain the carrier ； (6) After introducing the active metal component onto the carrier, it is dried and calcined to obtain the hydrogenation catalyst. The catalyst of the present invention not only possesses high hydrogenation demetallization activity and the ability to remove impurities such as metals, but also ensures the stability of the catalyst during long-term operation of the device.
