Abstract From the Canadian patent

CATALYTIC COMPOSITION FOR THE ISOMERIZATION OF PARAFFINIC HYDROCARBONS", ABSTRACT, Superior hydrocarbon isomerization performance is obtained with a catalytic composite comprising a platinum group metal component and a hydrogen-form crystalline mordenite incorporated with a refractory inorganic oxide. The superior performance is a direct result of the catalyst composite having a surface area of at least 580 m2/g. A novel method of preparing an isomerization catalyst having a surface area of at least 580 m2/g is presented, along with a novel process for the isomerization of isomerizable hydrocarbons. A key advantage of the novel process is the ability to operate successfully in the presence …
