| 摘要 |
An iridium-containing catalyst, particularly one comprising platinum, iridium, and silver, and preferably platinum, iridium, silver and halides, composited with a porous inorganic oxide base, is found useful in hydrocarbon conversion reactions, particularly reforming (hydroforming). A naphtha or straight run gasoline can be contacted with such catalyst at reforming conditions in the presence of hydrogen to improve the octane quality of the naphtha or gasoline.
