1. A process for increasing a research octane number (RON) and simultaneously reducing benzene content of a feed, the process comprising:
integrating an alkylation reactor (A) with a fluid catalytic cracking (FCC) regenerator (B), wherein the integrating comprises:
continuously withdrawing a hot regenerated catalyst from the FCC regenerator, wherein the FCC regenerator is configured to combust coke on a catalyst to generate the hot regenerated catalyst;
contacting the hot regenerated catalyst with a stream comprising a light olefin and a stream having 10 wt % benzene to produce alkyl aromatics in the alkylation reactor; and
sending back a spent catalyst to the FCC regenerator, wherein the catalyst comprises an FCC catalyst and 5-50 wt % of ZSM-5 additive.
