1310269 Hydrocarbon conversion catalysts UNIVERSAL OIL PRODUCTS CO 1 July 1970 [3 July 1969] 31807/70 Heading B1E [Also in Division C5] Catalysts comprise platinum, rhenium, germanium, and optionally a halogen, on a porous carrier. They may be formed by impregnating the carrier with compounds of the metals and any halide, drying and calcining in air. The metal oxides are preferably reduced with hydrogen in the absence of water and the reduced catalyst may be sulphided. |
