Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
81 words
In a process for reforming hydrocarbons in the presence of a catalyst at 450°-600° C, the improvement which comprises employing as said catalyst a new catalyst consisting essentially of a. alumina b. metallic platinum c. metallic iridium d. manganese in the form of manganese oxide and e. halogen, the catalyst contents by weight with respect to the alumina being 0.005-1% of platinum, 0.005-1% of iridium, 0.005-5% of manganese expressed as manganese metal, and 0.1-10% of halogen in the form of halide.
Claim 2
Dependent Claim
