Abstract
Abstract A novel catalyst precursor which comprises a Group IV-B transition metal oxide deposited on the surface of an inorganic metal oxide support, preferably alumina; especially where the Group IV-B transition metal oxide is deposited on the support surface as discrete areas separated by areas of support surface which contain little, if any, of said Group IV-B transition metal oxide; and a catalyst composition comprised of a cluster of a Group IV-B transition metal oxide and a Group VIII metal preferably a Group VIII noble metal, deposited on an inorganic metal oxide support, particularly an alumina support, especially where the clusters are deposited on the surface of the support, as discrete clusters separated by areas of support surface which contain little, if any, of said Group VI-B transition metal oxide, or clusters of said Group IV-B and Group VIII metals.

Claim 9
Dependent Claim
100 words
A process for the preparation of novel catalyst compositions which comprises forming a nonaqueous solution of a compound, or compounds, of titanium metal, contacting an inorganic metal oxide support with said solution to impregnate said solution into said support, drying and calcining said support in a moist atmosphere to form and deposit titanium metal oxide onto said support surface, and contacting said impregnated support with a solution of a Group VIII noble metal compound to form clusters of said titanium metal oxide and Group VIII noble metal on the surface of said support, and thereafter, drying and calcining said support.
Claim 10
Dependent Claim
100 words
A process for the preparation of novel catalyst compositions which comprises forming a nonaqueous solution of a compound, or compounds, of titanium metal, contacting an inorganic metal oxide support with said solution to impregnate said solution into said support, drying and calcining said support in a moist atmosphere to form and deposit titanium metal oxide onto said support surface, and contacting said impregnated support with a solution of a Group VIII noble metal compound to form clusters of said titanium metal oxide and Group VIII noble metal on the surface of said support, and thereafter, drying and calcining said support.
