Estimating the term…
Method for the dehydrogenation or dehydrocyclization of paraffins, for dehydrogenation of olefins with from 2 to 20 carbon atoms, and for hydrodealkylation of naphthalene homologs at temperatures ranging from 300.degree. to 650.degree. C on a catalyst comprising a palladium base alloy containing rhenium, tungsten or a combination of tungsten and ruthenium. The method can find application in the production of monomers, such as isoprene, for synthetic materials, pharmaceuticals, in processing petroleum hydrocarbons and natural gas.
A method for the selective preparation of aromatic hydrocarbons by the hydrodealkylation of alkylaromatic hydrocarbons, which comprises the passing of a vaporized alkylaromatic hydrocabon feedstock at a temperature of 300.degree. to 680.degree. C over a catalyst in the form of a foil made of palladium alloyed with at least one member selected from the group consisting of rhenium, tungsten, and a combination of tungsten and ruthenium, the content of palladium in said alloy ranging from 60 to 99 weight percent.
