SELEKTIEVER HYDRIERUNGSKATALYSATOR MIT GROSSEN MAKROPOREN.

摘要

A catalyst especially suitable for the selective hydrogenation of diolefinic hydrocarbons in the presence of monoolefinic hydrocarbons comprises an alumina support, from 0.05 to 1.5 wt. % of sulphur and from 1.0 to 25 wt. % of nickel. The support has a high proportion of large pores, with a total pore volume from 1.4 to 3 cm<3>/g and a surface area greater than 150 m<2>/g, with less than 25 percent of the total pore volume being present in pores having diameters of less than 150 Angstroms, and over 60 percent of the total pore volume being present in pores having diameters of more than 600 Angstroms.
