Among the most important hydroconversion processes in today's refineries are those that improve the viscosity and combustion properties of hydrocarbons via paraffin isomerization.  Industrial catalytic applications range from light naphthas (gasoline octane improvement) to diesel fuels (cold flow properties) to lubricants (viscosity index).   Hydroisomerization catalysts are also important for production of advanced fuels from alternative feedstocks such as  biomass and  gas-to-liquid products . Zeolite catalysts containing noble metals have superseded amorphous, supported metal catalysts for the majority of these processes. These new zeolite catalysts require metal-acid site intimacy, intraparticle diffusion, transition �state shape-selectivity, and acid-metal balance considerations well beyond those of earlier amorphous catalysts.   This presentation will examine the interplay of fundamental measurements that assist in the design of highly selective and active fuels and lubes isomerization catalysts.  The presentation will also provide a survey of the current and prospective applications of these catalysts.
