A process for converting hydrocarbons by a combination of fluid catalytic cracking and alkylation or aromatization of at least a part of the cracked product by contacting a hydrocarbon chargestock with a mixture of cracking catalyst and ZSM-5 type catalyst under cracking conditions; separating the mixture of cracking catalyst and ZSM-5 type catalyst from the cracked product; contacting at least a part of the cracked product with fresh ZSM-5 type catalyst under alkylation or aromatization conditions; separating the ZSM-5 type catalyst from the alkylated or aromatized product; and combining the ZSM-5 type catalyst separated from the alkylation and aromatization step with the mixture of cracking catalyst and ZSM-5 type catalyst.
