    摘要： A process to prepare propylene showing desirably increased selectivity comprises contacting, at an elevated temperature, ethanol and a rhenium oxide-modified ZSM-5 zeolite catalyst, under conditions suitable to form propylene. The rhenium oxide-modified ZSM-5 zeolite catalyst may be prepared by impregnating, in an aqueous or organic medium, a ZSM-5 zeolite with a rhenium source, under conditions suitable to form a catalyst precursor, and calcining the catalyst precursor under conditions suitable to form a rhenium oxide-modified ZSM-5 zeolite catalyst.

    摘要： Dispersed Active Metal catalyst for hydrogenation reactions is produced by treating a substantially catalytically inactive metal particulate with a solution capable of oxidizing the metal particulate and comprising of at least one compound of a hydrogenation catalyst metal thereby forming a layer of at least one of hydroxides and oxides thereon. The metal particulate is activated by treatment with a hydrogen-containing gas at elevated temperatures to form a porous layer of Dispersed Active Metal catalyst. Preferably, the treated metal particulate is dried prior to activation, and also preferably calcined in an oxidant-containing atmosphere prior to activation. The treatment solution may advantageously contain a compound of at least one promoter metal for the added catalyst metal. The porosity of the layer provides enhanced catalyst activity as well as improved methane selectivity in the Fischer-Tropsch process.

    摘要： A process for dehydrogenating alkane or alkylaromatic compounds comprising contacting the given compound and a dehydrogenation catalyst in a fluidized bed. The dehydrogenation catalyst is prepared from an at least partially deactivated platinum/gallium catalyst on an alumina-based support that is reconstituted by impregnating it with a platinum salt solution, then calcining it at a temperature from 400° C. to 1000° C., under conditions such that it has a platinum content ranging from 1 to 500 ppm, based on weight of catalyst; a gallium content ranging from 0.2 to 2.0 wt %; and a platinum to gallium ratio ranging from 1:20,000 to 1:4. It also has a Pt retention that is equal to or greater than that of a fresh catalyst being used in a same or similar catalytic process.
