Abstract
A catalyst composition comprising a special support of alumina and an amount of silica in the range of from 0.3 wt % to 10 wt % of the total weight of the support, a cobalt component, and a high concentration of a molybdenum component that exceeds 12 wt % of the total weight of the catalyst composition. The catalyst composition is highly active toward the desulfurization of an olefin-containing feedstock having a sulfur concentration while being selective toward the hydrogenation of the olefins contained in the feedstock and is used in a novel process for the selective desulfurization of an olefin-containing feedstock.
