ABSTRACT:
A supported catalyst for selective hydrogenation of acetylenes comprising 3-15 wt. % Ni promoted with 0.005-0.2 Pd on a support. The catalyst is prepared by depositing nickel promoted with palladium on a support, containing one or more optional elements from copper, silver, Group IA (Li, Na, K, Rb, Cs, Fr) and Group IIA (Be, Mg, Ca, Sr, Ba, Ra) and B (Zn, Cd,) of the periodic table of elements and characterized as:ComponentRange of componentPreferablywt. %wt. %Ni3-15 4-11Cu0-I 0.0-0.6Pd0.005-0.2 0.01-0.1 Ag0-100-5Group IA 0-2.5 0-1.5Group IIA & B0-250.1-5.
