Abstract: Modified crystalline zeolite materials have a zeolite framework with both tetra-coordinate Lewis aluminum single sites and Brønsted aluminum sites. The tetra-coordinate Lewis aluminum single sites include aluminum atoms covalently bonded to a variable group and to two oxygen atoms and further coordinated to a third oxygen atom. The variable group may be alkyl, hydride, or hydroxyl. Methods for incorporating tetra-coordinate Lewis aluminum single sites into a crystalline zeolite material include contacting the crystalline zeolite material with a dialkylaluminum hydride R2AlH, where each R is alkyl, to react the dialkylaluminum hydride with the zeolite framework and form tetra-coordinate alkyl aluminum single sites. Heating the alkyl-aluminum zeolite induces ?-hydride elimination of the alkyl groups, whereby tetra-coordinate aluminum hydride single sites are formed.

Abstract: A process for upgrading a hydrocarbon feed includes passing the hydrocarbon feed and an aromatic bottoms stream to an FCC unit including an FCC reactor and a catalyst regenerator. The hydrocarbon feed is hydrogen-rich having at least 12 wt. % hydrogen, and the aromatic bottoms stream is a bottoms stream produced from an aromatics recovery complex for processing reformate from naphtha reforming. The hydrocarbon feed and aromatic bottoms stream are cracked over the FCC catalysts to produce an effluent and spent FCC catalysts having coke deposits. The spent FCC catalyst is regenerated through combustion of the coke deposits. The hydrogen-rich hydrocarbon feed does not produce enough coke to satisfy the heat demand of the FCC reactor. Cracking the aromatic bottoms stream increases the amount of coke so that combustion of the additional coke during regeneration produces additional heat to satisfy the heat demand of the FCC reactor.
