Abstract: The binderless zeolite of this invention is comprised more than 90% of crystalline aluminosilicate which is produced by crystalized a binder contained in extrudate obtained by molding a mixture of crystalline aluminosilicate and binder of silica-alumina. This binderless zeolite can improve it's catalytic activity without weaken the strength of the extrudate, since a so-called secondary pores also act as catalyst. Especially, when more than 50% of TSZ zeolite is contained, the catalytic ability of binderless zeolite is so excellent that it is preferably used as the catalyst for selective cracking of n-parafins of alkylation of aromatics using alkylation agents such as alcohols and olefins.

Abstract: 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.
