Claims
- 1. A hydrocarbon conversion process which comprises contacting a hydrocarbon under hydrocracking conditions with a catalyst produced by:
- heating an alumina supported Pt, Ir, Os, Ru, Rh, or Pd metal catalyst at a temperature within the range of 500.degree. to 1600.degree. F.;
- contacting said catalyst at said temperature of 500.degree. to 1600.degree. F. with a dry activating gas comprising a hydrogen halide selected from the group consisting of HC1 and HBr, a halosilane selected from the group consisting of chlorosilanes and bromosilanes, and an organic halide selected from the group consisting of organic chlorides and organic bromides; and
- thereafter cooling the thus-contacted catalyst.
- 2. A process according to claim 1 wherein said feed is a C.sub.5 or higher boiling hydrocarbon.
- 3. A process according to claim 1 wherein said feed is n-octane and wherein said n-octane is converted to butane.
- 4. A process according to claim 1 wherein said hydrocracking conditions are: pressure, 100-3000 psig; temperature, 300.degree.-700.degree. F., liquid hourly space velocity, 0.5-20 and H.sub.2 /hydrocarbon mole ratio 2-20.
- 5. A method according to claim 4 wherein said organic chlorides are chlorinated paraffins and said organic bromides are brominated paraffins and wherein a weight ratio of halosilane to said organic halide is within the range of 0.1:1 to 10:1.
- 6. A method according to claim 1 wherein said organic chlorides are chlorinated paraffins and said organic bromides are brominated paraffins and wherein a weight ratio of halosilane to said organic halide is within the range of 0.1:1 to 10:1.
- 7. A method according to claim 1 wherein said temperature for contacting said catalyst with said activating gas is within the range of 1200.degree. to 1500.degree. F. and said contacting of said catalyst is carried out for a time within the range of 0.1 to 10 hours and wherein said hydrogen halide is anhydrous hydrogen chloride, said halosilane is a chlorosilane of the formula SiX.sub.4 in which each X can be the same or different and wherein at least one X is chlorine and the other X substituents are selected from the group consisting of chlorine, hydrogen, and alkyl radicals containing from 1 to 3 carbon atoms per molecule and said organic halide is a chlorinated paraffin containing from 1 to 3 carbon atoms per molecule.
- 8. A method according to claim 7 wherein said metal is platinum and is present in an amount within the range of 0.1 to 1 weight percent based on the weight of said catalyst, said halosilane is silicon tetrachloride, said organic halide is ethyl chloride, and said activating gas is carried by a stream of hydrogen.
