Abstract:
1. A method of screening catalysts for liquid-phase selective hydrogenation comprising: preparing a test catalyst by adding a promoter selected from the group consisting of Group IB metals, Group IIB metals, Group IIIA metals, Group VIIB metals, and combinations thereof, to a reference catalyst comprising a supported Group VIII metal catalyst precursor; preparing a liquid reactant comprising C separately testing both the test catalyst and the reference catalyst by contacting the liquid reactant and a gas mixture comprising hydrogen and carbon monoxide in continuous flow with each of the test catalyst and the reference catalyst, respectively, at selective hydrogenation reaction conditions to produce a product stream from each of the test catalyst and the reference catalyst, condensing substantially all of the n-methyl-2-pyrrolidone from each product stream; measuring the concentrations of products comprising C determining performance parameters for both the test catalyst and the reference catalyst respectively, wherein the performance parameters comprise the respective C comparing the performance parameters of the test catalyst with the performance parameters of the reference catalyst.
