  5. 5. Fluid Catalytic Cracking Catalyst Demetallization and Reactivation, Modeling of Catalytic Cracking, and Use of Microwaves to Heat Fluid Beds

    Author : Frank J. Elvin; Chalmers University of Technology; []
    Keywords : pilot plant; nickel and vanadium deposition; catalyst; reactivation; demetallization; catalytic cracking; and microwave heating; MAT; fluid bed;

    Abstract : The fluid catalytic cracking unit (FCCU), the major conversion unit in an oil refinery, uses a silica-alumina zeolite catalyst to convert heavy hydrocarbons to light hydrocarbons. A small fraction of the catalyst must be continually replaced with fresh catalyst to maintain activity. READ MORE
