This paper summarizes the work on the development of a novel catalyst formulation for the complete oxidation of oxygenated volatile organic compounds (VOCs) at low-temperature in the exhaust gases from flexographic printing and bakery applications. VOCs present in flexographic exhaust gases typically include ethyl and propyl alcohols, acetates and ketones, whereas ethanol is the primary VOC in bakery applications. The new catalyst formulation is a combination of noble metal and metal oxides supported on alumina beads. This formulation is a drop-in replacement for available commercial bead products, which is a noble metal on alumina catalyst. The new catalyst operates at inlet temperatures 75{degree}F to 200{degree}F lower than the commercial noble metal catalyst depending on the VOC considered and exhibit adequate resistance to poisoning by sulfur. Full size test units have operated successfully for over six months in two flexographic printing operations. Aged catalyst samples from these field units show good performance in lab tests.
