Abstract: The present invention provides a process of preparing a high coordination sulfated mixed metal oxide catalyst. The process comprises mixing specific ratios of alumina and zirconia mixtures at specific particle size limits which do not exceed 37 ?m, in the presence of a combination of ?-amino acids, i.e., non-polar side chains and basic side chains having molecular weight less than 250, nitric acid (HNO3) and sulfuric acid (H2SO4) at a pH range of 1.5 to 3.8 at temperatures below 30° C. The catalysts have a high conversion towards hydrocarbon isomerization reaction while concurrently having crushing strength in range of 2.0 daN and 5.0 daN, allowing for efficient commercial application.

Abstract: An emission control catalyst that exhibits improved CO and HC reduction performance includes supported precious group metal catalysts that are coated onto different layers of the substrate for the emission control catalyst. Zeolites of one or more types are added to the emission control catalyst as a hydrocarbon absorbing component to boost the low temperature performance of the emission control catalyst. Y zeolite is used by itself or mixed with other zeolites to enhance hydrocarbon storage at low temperatures.
