Abstract
Abstract Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a platinum-free catalytic composite containing catalytically effective amounts of palladium, iridium and halogen combined with a porous carrier material. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a gasoline fraction in the presence of hydrogen, which comprises contacting the gasoline fraction and hydrogen, at reforming conditions, with a platinum-free combination of catalytically effective amounts of a palladium component, an iridium component and a chlorine component with a gamma-alumina carrier material.
