Catalyst composite material for hydrocarbon reactions.

摘要

Novel catalyst composite material is disclosed which comprises in combination a crystalline metallosilicate zeolite in terms of mole ratios having the general formula : O-below 0.4 X : M2O3 : 30-300 SiO2 : 10 H2O wherein M is iron, lanthanum or mixtures thereof and X is selected from the oxides of sodium, hydrogen, platinum, iridium, rhenium and mixtures thereof, alumina and a chlorine component. This catalyst has a long and stable activity and no loss of components is encountered during the reforming of pyrolysis naptha and more importantly it is observed that the pyrolysis naptha does not have to be hydrogenated prior to contacting it with the catalyst. Reforming of pyrolysis naptha no a liquid fraction containing more than 99 % of aromatic hydrocarbons is achieved.
