  • Publication number: 20240182797
    Abstract: The present invention relates to an integrated process for conversion of crude oil to petrochemicals viz. olefins and aromatics. More specifically, the present invention provides a configuration of processes both primary and secondary processing units through which the crude oil can be converted to petrochemicals. The configuration of processes provided by the present invention utilizes minimum numbers of secondary processing units and provides great degree of flexibility towards maximizing yield of either petrochemical or fuels depending upon market scenario.

  • Publication number: 20230331645
    Abstract: A process for the upgrading of hydrocarbon streams, i.e., processing any hydrocarbon feed streams rich in benzene and sulphur compounds. The process for simultaneous hydrodesulfurization and benzene conversion to higher alkylated aromatic molecules (C7 to C10 aromatics), without need of prior treatment like distillation, or sulfur removal. The hydrocarbon feed streams are processed over sulfided metal catalyst impregnated on acid support simultaneously desulfurizes and alkylates the benzene molecules.
