The activity of a nickel-based catalyst generated by a plasma method baa been evaluated in the hydroconveraion of a deaaphalted vacuum residue. Thin material exhibits a significant activity at low catalyst-to-charge ratio. When used at concentrations aa low aa 100 to 200 ppm vs. charge, it limits th
