✦ Synopsis
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 the production of gases and light productq it prevents the formation of coke deposita and avoids the aromatization of the feed. These properties permit an efficient utilization of hydrogen during hydroconversion processes.
