Title: Catalysts methods for producing acetic acid from ethane oxidation using MO, V, PD and NB based catalysts, processes of making same and methods of using same

Abstract: An oxide catalyst comprising the elements Mo, V, Nb and Pd. The novel catalytic system provides both higher selectivity and yield of acetic acid in the low temperature one step vapor phase direct oxidation of ethane with molecular oxygen containing gas without production of side products such as ethylene and CO. The feed gas is contacted with a catalyst containing Mo, V, Nb, Pd and O in the ratio a:b:c:d:x where a is 1 to 5; b is 0 to 0.5; c is 0.01 to 0.5; d is 0 0.2 and x is a number determined by the valence of the other elements in the catalyst.
