  • Patent number: 11891356
    Abstract: A process for conversion of hydrocarbon feedstock into lighter olefins of C2 to C4 carbons, the process comprising of cracking the hydrocarbon feedstock in a reactor in the presence of a catalyst. The catalyst for short contact time catalytic cracking process of heavy hydrocarbons having contact time less than 1 second to produce light olefins of C2 to C4 carbon in the range of 40 to 60 wt % on fresh feed basis in a fluidized bed reactor which is concentric downflow reactor in presence of catalyst consisting of ultra-stable Y zeolite in the range of 5-10 wt %, 4 to 8 wt % of pentasil zeolite, 2.5-5 wt % of bottom selective material, 0.5-2 wt % of rare earth and 75-88 wt % of support material.
    Type: Grant

  • Patent number: 11421162
    Abstract: The present invention relates to a process for converting the waste plastics along with the petroleum feedstock in a Catalytic Cracking Unit, in particular a Fluid Catalytic Cracking Unit employed in petroleum refineries. The invention also provides a method and hardware system to enable waste plastic to fuel conversion along with hydrocarbon catalytic cracking. The invented process aims to convert any type of waste plastic including polystyrene, polypropylene, polyethylene, metal containing Polyethylene-Polypropylene multilayer plastics & other metal containing plastics along with the petroleum derived feedstock such as vacuum gas oil, reduced crude oil, vacuum residue etc. in catalytic cracking unit.
