Abstract

A method of producing a catalyst composition is provided, the method comprising mixing (i) a first component comprising a zeolite, and (ii) a second component comprising a homogeneous solid mixture containing at least one catalytic metal and at least one metal inorganic support, wherein the first component and the second component form an intimate mixture, and wherein the homogeneous solid mixture is produced by mixing a reactive solution comprising a precursor of the metal inorganic support and a templating agent with a precursor of the catalyst metal, and calcining the mixture to form the homogeneous solid mixture. The templating agent affects one or more of pore size, pore distribution, pore spacing, or pore dispersity of the metal inorganic support. The pores of the solid mixture produced after calcination may have an average diameter in a range of about 1 nanometer to about 15 nanometers.
