1. A method of producing a catalyst composition, the method comprising:
forming a slurry comprising an initial zeolite material, a surfactant, silica, and metal precursors, wherein the metal precursors comprise a nickel-containing compound and a silver-containing compound;
extruding the slurry to produce an extrudate;
drying and calcining the extrudate to form a dried and calcined extrudate;
hydrothermally treating the dried and calcined extrudate to form a hydrothermally-treated extrudate, wherein the hydrothermal treatment is at a temperature of from 50° C. to 250° C.; and
drying and calcining the hydrothermally-treated extrudate to produce the catalyst composition, wherein the catalyst composition comprises zeolite, one or more oxides of nickel, and one or more oxides of silver.
