Abstract: The present disclosure relates to zeolite-containing catalysts useful in the transalkylation of aromatic hydrocarbons, such as the isomerization of ethylbenzene, to methods for making such catalysts, and to methods for aromatic transalkylation with such catalysts. One aspect of the disclosure provides an aromatic transalkylation catalyst that includes one or more zeolites, an inorganic binder, a transition metal catalyst, and vanadium.

Abstract: The present disclosure relates to solid phosphoric acid (SPA) catalysts useful in the conversion of hydrocarbons, such as the oligomerization of olefins, to methods for making such SPA catalysts, and to methods for converting hydrocarbons by contacting hydrocarbons with such catalyst. For example, in certain embodiments, the disclosure provides a calcined solid phosphoric acid catalyst composition that includes phosphoric acid and silicon phosphates, and in which (i) one or more promoters each selected from the group consisting of boron, bismuth, tungsten, silver and lanthanum is present; (ii) the composition is a calcined product of a formable mixture including silica-alumina clay, silica fiber and/or silica alumina fiber; or (iii) the composition is a calcined product of a formable mixture including fumed silica.

Abstract: Ethylene glycol and propylene glycol may be made by hydrogenolysis of a polyol comprising the steps of reacting a polyol with hydrogen in the presence of a hydrogenolysis catalyst. The hydrogenolysis comprises nickel, one or more promoter, and one or more support. The promoter is selected from bismuth, silver, tin, antimony, gold, lead, thallium, cerium, lanthanum, and manganese. The support is selected from zirconia and carbon. A zirconia support comprises a zirconia textual promoter, which is selected from Cr, Mo, W, Nb, Ce, Ca, Mg, La, Pr, Nd, Al, and P. If the support comprises carbon, then the promoter is selected from bismuth and antimony. In another embodiment, if the support comprises carbon, then both the promoter is selected from bismuth and antimony, and the catalyst comprises copper. In another embodiment, the catalyst additionally comprises copper.
