ABSTRACT:
A process for treating an organic stream containing a non-distillable component to produce an organic vapor stream and a solid which process comprises the steps of: (a) contacting the organic stream containing a non-distillable component with a hydrogen-rich gaseous steam having a temperature greater than the organic stream in a flash zone at flash conditions thereby increasing the temperature of the organic stream and vaporizing at least a portion thereof to produce an organic vapor stream comprising hydrogen and a heavy stream comprising the non-distillable component; and (b) reacting at least a portion of the heavy stream comprising the non-distillable component in the presence of hydrogen in a pyrolysis zone to produce a thermally stabilized volatile organic stream comprising hydrogen and a solid.
