The present invention relates to an integrated process for increasing the research octane number (RON) of FCC gasoline with simultaneous reduction in benzene content. In this process, benzene rich gasoline fraction is reacted with light olefin rich gaseous streams like FCC off gas/dry gas, coker off gas to produce alkyl aromatics using FCC catalyst system containing ZSM-5 zeolite. The catalyst is continuously drawn from the FCC regenerator by suitably placing the alkylation reactor in communication with the FCC regenerator. The product stream of the alkylation reactor is routed to main fractionator for separation of off gas and benzene lean gasoline. This integrated process not only improves the octane number of gasoline but also lowers the gasoline benzene content. Further the integrated alkylation reactor system acts as a heat sink lowering the FCC regenerator temperature and enables the FCC unit to process high CCR feeds.
