  • Patent number: 12091615
    Abstract: The present disclosure relates to an FCC catalyst composition and a process for preparing the same. In a first aspect, there is provided an FCC catalyst composition comprising 25 to 45 wt % Y-type zeolite, 20 to 40 wt % silicon oxide, 5 to 25 wt % alumina, 5 to 35 wt % of at least one clay and 0.5 to 3 wt % of at least one rare earth oxide. The weight % of each of the component is with respect to the total weight of the composition. The FCC catalyst composition has an average particle size in the range of 45-120?. In a second aspect, there is provided a process for preparing the FCC catalyst composition, which uses ball milled pseudoboehmite having an average particle size in the range of 1 to 8 micron and the whole process is carried out at a pH value in the range of 6 to 7.
    Type: Grant
    Filed: October 3, 2020
    Date of Patent: September 17, 2024
    Assignee: Reliance Industries Limited
    Inventors: Ravichandran Gopal, Nirav Jethalal Jani, Ankit Vipinkumar Patel, Asit Kumar Das
  • Publication number: 20220379288
    Abstract: The present disclosure relates to an FCC catalyst composition and a process for its preparation. The FCC catalyst composition comprises Y type zeolite, silicon oxide, alumina, at least one clay, at least one rare earth metal, and at least one metal oxide. The FCC catalyst composition of the present disclosure provides improved yields of high value gasoline such as propylene and LPG and reduces yields of low value hydrocarbons such as CSO and LCO.
