Patent ID: 8518851

Claim:
A catalyst for the hydrogenation of unsaturated hydrocarbons, which catalyst is a supported nickel on silica catalyst, has a nickel content of 40 to 85 weight-% (calculated as NiO), a silicon content of 15 to 60 weight-% (calculated as SiO 2 ), a titanium content of 0.5 to 5.0 weight-% (calculated as TiO 2 ), and does not contain more than 0.20 weight-% iron (calculated as Fe), wherein the catalyst has a monomodal Ni-crystallite size distribution with a mean crystallite size of the reduced catalyst of 1.5 to 3.5 nm, a pore volume of at least 0.60 ml/g and wherein the proportion of the pore volume of pores with a pore diameter of ≧10 nm is at least 55%.
