Catalytic conversion process capable of reducing yields of dry gas and coke

The present disclosure relates to a catalytic conversion process capable of reducing yields of a dry gas and coke. The method comprises the following steps: performing a first catalytic reaction on aheavy hydrocarbon oil raw material in a first reactor to obtain a first coked catalyst and a first product; performing a second catalytic reaction on a light hydrocarbon in a second reactor to obtaina second coked catalyst and a second product; introducing the first coked catalyst and the second coked catalyst into strippers, performing stripping, introducing a first stripped catalyst into an oxygen-containing fluidization zone of a regenerator, and performing aerobic regeneration; and introducing a second stripped catalyst into an anaerobic fluidization zone of a regenerator, and performinganaerobic regeneration at 600-800 DEG C. Compared with the prior art, the method disclosed in the invention can prepare more low-carbon olefins in catalytic conversion of heavy hydrocarbon oil, and the yields of the dry gas and
