The invention is directed to a catalyst suitable for the hydrogenation of
hydrocarbon resins, comprising a supported nickel on silica and alumina
catalyst, said catalyst having a nickel content of 45 to 85 wt. %, a
silicon content, calculated as SiO.sub.2, of 14 to 45 wt. %, an aluminium
content, calculated as Al.sub.2O.sub.3, of 1 to 15 wt. % an iron content,
calculated as Fe, 0.25 to 4 wt. %, all percentages having been calculated
on the basis of the reduced catalyst, and which catalyst has a volume of
pores between 2 and 60 nm, as defined herein, of at least 0.35 ml/g of
catalyst.
