  • Catalyst for hydrorefining
    Patent number: 5648311
    Abstract: The invention relates to a catalytic hydrorefining of mixtures of hydrocarbons which contain hetero atoms such as nitrogen, sulphur, halogens and/or oxygen. The characterizing feature of the invention is that nickel or a nickel-molybdenum alloy containing more than 30% nickel, residue molybdenum, is thermally treated in an air atmosphere at temperatures of 400.degree. to 1200.degree. C. for a period of 0.25 to 10 hours, whereafter it is subjected to a hydrogen activation in the temperature range of 200.degree. to 600.degree. C.
