  • Patent number: 11732200
    Abstract: 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.

  • Patent number: 11661556
    Abstract: The present invention relates to a sequential thermo-chemical treatment along with adsorption-based pre-treatment process for residual oils having a very high naphthenic acid content. First stage of the process is a thermal pre-treatment step which results into generation of hydrocarbon stream with a reduced naphthenic acid content due to high temperature. In second stage of pre-treatment, generated hydrocarbon stream from stage-1 is subjected to esterification reaction with alcohol, such as methanol, to further reduce the TAN of hydrocarbon stream. After recovery of alcohol from the reaction mixture, depending on TAN reduction required reaction mixture may be subjected to an adsorption stage, third stage pre-treatment, where an adsorbent mixture comprising of FCC spent catalyst is used to adsorb the TAN of feed hydrocarbon stream. The treated hydrocarbon stream is then co-processed with DCU feed stock for producing lighter hydrocarbons.
