Hydrocarbon conversion with platinum second metal catalysts in proportions which form ordered alloys
Abstract
Abstract A HYDROCARBON CONVERSION CATALYST OF 0.01-10% WT. METAL ON A REFRACTORY SUPPORT CONTAINS PLATINUM AND A SECOND METAL WHICH FORMS A SOLID SOLUTION WITH PT, THE ATOMIC AMOUNTS OF EACH BEING EQUIVALENT TO AMOUNTS FORMING ORDERED ALLOY STRUCTURES. THE SECOND METAL MAY BE CO, NI, FE, CU, SN, PD (PARTICULARLY THESE SIX), IR, RH, AG, AU, BI, HG, SB, PD OR CD AND PREFERABLY THERE IS AT LEAST 45 ATOMIC PERCENT PT. THE CATALYSTS MAY BE PREPARED BY KNOWN IMPREGNATION OR ION-EXCHANGE TECHNIQUES AND ARE PREFERABLY REDUCED BEFORE USE AT 250-600*C. THE PREFERRED USE IS DEHYDROCYCLISATION OR DEHYDROGENATION OF C3-C25 HYDROCARBONS, PARTICULARLY THE CATALYTIC REFORMING OF 15-204*C. BOILING RANGE PETROLEUM FRACTIONS. D R A W I N G
