"TREATING A TEMPERATURE-SENSITIVE HYDROCARBONACEOUS STREAM" ABSTRACT A temperature-sensitive hydrocarbonaceous stream containing a non-distillable component is treated to produce a hydrogenated distillable hydrocarbonaceous product while minimizing thermal degradation of the hydrocarbonaceous stream by: (a) contacting the hydrocarbonaceous stream with a first hot hydrogen-rich gaseous stream at conditions effective to provide a hydrocarbonaceous vapor stream comprising hydrogen and a heavy stream comprising the non- distillable component; (b) contacting the vapor stream with a hydrogenation catalyst in a reaction zone at hydrogenation conditions selected to increase the hydrogen content of the hydrocarbonaceous compounds contained therein; (c) condensing the resulting effluent from the reaction zone to provide a second hydrogen-rich gaseous stream and a liquid stream; (d) reacting at least a portion of the heavy stream from step (a) in a thermal coking zone at thermal coking conditions to provide a thermal coking zone effluent stream; and, (e) recovering the hydrogenated distillable hydrocarbonaceous product stream from the liquid stream from step (c) and from the effluent stream from step (d).
