Catalytic cracking of light coker gasoil

Results are presented from experiments on the catalytic cracking of light gas-oil produced by delayed coking of a low-sulfur vacuum resid. A proposal is given for the utilization of these products. The physicochemical properties of the light gas-oil are analyzed. Results of the study show that cat cracking of vacuum gas-oil together with light coker gasoil in a two-stage unit gives substantial increases in the resources of cat cracker feed--in the capacity of the unit, and in the output of light products.
