Catalytic conversion of hydrocarbons by improved zeolite catalyst
Patent
·
OSTI ID:7363921
A method is claimed for catalytically converting at least a portion of a hydrocarbon feed which comprises contacting said hydrocarbon feed at hydrocarbon conversion conditions with a catalyst comprising a metal, hydrogen ion-exchanged aluminosilicate wherein the metal is selected from the group consisting of aluminum, zirconium and chromium, the improvement which comprises preparing said metal, hydrogen, ion-exchanged aluminosilicate by a process comprising heating an aqueous slurry of a nitrogen compound forming ammonia on hydrolysis and a water-soluble salt of said metal with a predominantly ammonium-exchanged crystalline aluminosilicate having pores of diameter of about 6 to 15A. and a silica-to-alumina mole ratio of about 2:1 to about 20:1 to allow the metal to precipitate within the lattice structure of the aluminosilicate, and calcining the resulting material to form a metal, hydrogen ion-exchanged crystalline aluminosilicate, said process adding about 0.5 to 15 percent by weight of said metal based upon the total weight of the aluminosilicate on an ignited basis.
