This invention relates to the preparation of a novel Si/HZSM-5 catalyst through vapor phase deposition of Si on the surface of HZSM-5 catalyst which is obtained by ion exchanging ZSM-5 catalyst. The source of deposition Si comes from tetraalkyl ortho-silicate (or tetra-alkoxy silane), Si(OR)4, wherein R represents the alkyl group that contains 1-4 carbon atoms. The silicon deposit will substantially not clog the pores of the catalyst. The present invention is to make use of the modified catalyst in the alkylation or disproportionation reactions in order to enhance the yield of p-dialkylbenzene as an ingredient in the final product of aryl compounds such as toluene or ethylbenzene.

Novel silicon-modified catalyst Si/HZSM-5, it's preparation, and a

This invention provides a method for producing cyclohexanone from cyclohexanol using oxidative dehydrogenation. More particularly, this invention comprises adding a certain amount of a gaseous oxidant to the cyclohexanol feed stream; and, converting the cyclohexanol to cyclohexanone over a CuO-ZnO catalyst.

Method of producing cyclohexanone from cyclohexanol through oxidative

Heavy petroliferous stocks such as vacuum and atmospheric resids, tar sand oils, shale oils, liquids from conversion of coal and the like are concurrently distilled and hydroprocessed for removal of sulfur, nitrogen and metals and are hydrocracked or otherwise hydroprocessed in a packed distillation column under hydrogen pressure wherein the packing is constituted, at least to a substantial extent in both stripping and rectifying sections by catalyst suited to the desired conversions. In a specific application to catalytic hydrodewaxing of lubricating oil stocks, improvement of Viscosity Index (VI) of dewaxed product results.
