<p>A method for the preparation of a hydrocarbon conversion catalyst comprising a composite of a refractory support, or carrier, a Group VIII noble metal component, particularly platinum, a tin component, and a halogen component. Suitably, the catalyst composite can also contain a third metal component, or yet additional components. In the preparation of such catalyst, the tin is added from a solution of a soluble compound of tin comprised of an organo thionyl compound, or organic compound containing a thionyl group, whereby the tin component is uniformly dispersed from the surface into the inner part of a catalyst. Such catalyst 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 a naphtha or gasoline.</p> |
