ABSTRACT:
An improved method for making hydrogenated petroleum resins by subjecting the resin to hydrogenation in the presence of a sulfided nickel (2 to 10 wt. %)--tungsten (10 to 25 wt. %) catalyst supported on a gamma-alumina having fresh catalyst surface area ranging from 120 to 300 m.sup.2 /g under a hydrogen pressure of 150 to 200 atmospheres and at a temperature in the range 250.degree. C. to 330.degree. C. and the resins so produced.
