The disclosure provides a process to hydrodearylate the non-condensed alkyl-bridged multi-aromatics at the outlet of the clay tower where such multi-aromatics form rather than performing hydrodearylation on the reject stream of the aromatics complex. Hydrodearylation may feature combining a C.sub.8+ hydrocarbon stream from a clay treater with a hydrogen stream over a catalyst bed comprising a support and an acidic component optionally containing Group 8 and/or Group 6 metals.

Isobutanol may be converted into predominantly C.sub.12+ olefin oligomers under specified conditions. Such methods may comprise: contacting a feed comprising isobutanol with a zeolite solid acid catalyst having a MWW framework under conditions effective to convert the isobutanol into a product comprising C.sub.4n olefin oligomers, wherein n is an integer having a value of two or greater and about 80 wt. % or greater of the C.sub.4n olefin oligomers are larger than C.sub.8.

A process to produce aromatic compounds in a heavy oil product stream comprising the steps of separating the depressurized effluent to produce a vapor product stream and a liquid product stream, reducing a temperature of the vapor product stream to produce a cooled vapor product, separating the cooled vapor product to produce a light oil stream, wherein the light oil stream comprises olefins, separating the light oil stream to produce a light oil slip stream and a light stream, mixing the light stream with a water feed stream to produce an olefin-containing water stream, increasing a pressure of the olefin-containing water stream to produce a pressurized water feed, increasing a temperature of the pressurized water feed to produce a hot water feed, wherein a temperature of the hot water feed is greater than 450° C., converting olefins to aromatic compounds in the hot water feed.

A process for producing one or more of benzene, toluene, or mixed xylenes may include combining one or more aromatic feed chemicals, one or more aromatic-based polymers, hydrodearylation catalyst, and hydrogen in a hydrodearylation unit to form a chemical product. The process may also include passing the chemical product out of the hydrodearylation unit, where the chemical product comprises one or more of benzene, toluene, and mixed xylenes. Additionally, a system for producing one or more of benzene, toluene, or mixed xylenes may include a mixing unit and a hydrodearylation unit. An aromatic feed stream and an aromatic-based polymer stream may be in fluid communication with a mixing unit. A mixing unit effluent stream may be in fluid communication between the mixing unit and the hydrodearylation unit. A chemical product stream may be in fluid communication with the hydrodearylation unit.

The present invention relates to a hydrocarbon conversion catalyst, comprising: a first composition comprising a dehydrogenation active metal on a solid support, and a second composition comprising a transition metal and a doping agent, wherein the doping agent is selected from zinc, gallium, indium, lanthanum, and mixtures thereof, on an inorganic support.

A hydroprocessing catalyst with improved performance has been produced that involves an intimately mixed unsupported metal oxide with a zeolite or other acid function. The intimate mixing allows an intimate interaction between the unsupported metal oxide and the acid function. The hydroprocessing catalyst may be used alone or may be incorporated with a portion of a conventional hydrocracking catalyst.
