  • 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.

The present invention further provides a process for dehydroaromatizing a mixture comprising C1-C4-aliphatics by conversion in the presence of the catalyst.

  • Patent number: 8722950
    Abstract: The invention is for a process for producing propylene and hexene (along with ethylene, pentenes, product butenes, heptenes and octenes) by metathesis from butenes (iso-, 1- and cis and trans 2-) and pentenes and then aromatizing the hexenes (along with higher olefins, such as heptenes and octenes) to benzene (along with toluene, xylenes, ethylbenzene and styrene). Since the desired products of the metathesis reaction are propylene and hexene, the feed to the metathesis reaction has a molar ratio for 1-butene:2-butene which favors production of propylene and 3-hexene with the concentration of hexenes and higher olefins in the metathesis product being up to 30 mole %. An isomerization reactor may be used to obtain the desired molar ratio of 1-butene:2-butene for the feed composition into the metathesis reactor. After the metathesis reaction, of hexene and higher olefins are separated for aromatization to benzene and other aromatics.

  • Patent number: 8604262
    Abstract: A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.
