Abstract:
Process for hydrogenating aromatic compounds containing sulfur impurities by contacting the same, at a temperature in the range of from 200* to 450*C and under a pressure of from 10 to 200 Kg/cm2, in a first step, with a catalyst containing a desulfurizing element selected from the oxides and/or sulfides of molybdenum, tungsten, nickel and cobalt, and an iron oxide, deposited on an alumina carrier used in an amount of 0.25 to 4 times the iron oxide amount, and in a second step, with a metal hydrogenation catalyst.

Abstract:
An isomerization catalyst is manufactured by admixing an alumina carrier with a hydrogenating metal compound, an aluminum halide or a hydrocarbylaluminum halide and an aromatic poly (hydroxy, oxo and/or hydrocarbyloxy) compound. The resulting catalyst may be used for isomerizing saturated aliphatic or naphthenic hydrocarbons at 25*-400*C, particularly at 80*-200*C.
Abstract:
Saturated hydrocarbons are isomerized with a catalyst which incorporates chlorine and at least one compound of a metal from Groups VI-B and VIII on an alumina carrier. The chlorine is introduced into the catalyst as a mixture of (1) at least one chlorinating agent selected from chlorine and hydrochloric acid and (2) at least one carbon compound selected from carbon disulfide and carbon oxysulfide.
Abstract:
New catalyst, particularly suitable for dehydrogenating saturated hydrocarbons, which contains alumina, at least one metal selected from molybdenum, tungsten and rhenium and at least one metal selected from gallium, indium, thallium, germanium, tin, lead, antimony and bismuth, said catalyst having a specific surface from 20 to 150 m2/g and a neutralization heat by ammonia adsorption at 320*C under 300 mm Hg lower than 10 calories per gram.
