摘要
A process for converting inferior feedstock oil includes several steps. In step a) the inferior feedstock oil is subjected to a low severity hydrogenation reaction. The reaction product is separated to produce a gas, a hydrogenated naphtha, a hydrogenated diesel and a hydrogenated residual oil. In step b) the hydrogenated residual oil obtained in step a) is subjected to a first catalytic cracking reaction, the reaction product is separated to produce a first dry gas, a first LPG, a first gasoline, a first diesel and a first FCC-gas oil. In step c) the first FCC-gas oil obtained in step b) is subjected to a hydrogenation reaction of gas oil, the reaction product is separated to produce a hydrogenated gas oil, and in step d) the hydrogenated gas oil obtained in step c) is subjected to the first catalytic cracking reaction of step b) or a second catalytic cracking reaction.
