Abstract (en)

[origin: WO2013186789A1] In the present invention a selective hydrogenation catalyst composition comprising (a) an inorganic oxide carrier; and (b) fine-alloy particles of an active metal and a promoter metal components dispersed on the surface of the inorganic oxide carrier is disclosed. The improved dispersion of the active component is found to be around 30 % of surface area of the carrier surface as measured by H2 Chemisorption method. The improved dispersion of fine alloy particles of the present invention is accomplished by employing an equilibrium adsorption impregnation method.
