Abstract: A method that integrates a catalytic cracking process with a crude oil conversion to chemicals process is disclosed. The method may include contacting, in a catalytic cracking reactor, a mixture of the hydrocarbon stream comprising primarily C5 and C6 hydrocarbons from crude oil processing and a C4 to C5 hydrocarbon stream produced in a steam cracking unit with a catalyst under reaction conditions sufficient to produce an effluent comprising olefins.

Abstract: A method of forming a composite zeolite catalyst includes combining a silicon source and an aqueous organic structure directing agent having a polyamino cation compound to form a silica intermediary gel, introducing an aluminum precursor to the silica intermediary gel to form a catalyst precursor gel, evaporating water in the catalyst precursor gel to form a catalyst gel, and heating the catalyst gel to form a composite zeolite catalyst particle having an intergrowth region with a mixture of both Beta crystals and ZSM-5 crystals. An associated method of making xylene includes feeding heavy reformate to a reactor, the reactor containing the composite zeolite catalyst, and producing xylene by simultaneously performing dealkylation and transalkylation of the heavy reformate in the reactor, where each composite zeolite catalyst particle is able to catalyze both the dealkylation and transalkylation reactions.
