ABSTRACT:
An improvement is disclosed on selective vaporization for decarbonizing and demetallizing heavy petroleum stocks by short time riser contact with hot inert solid contact material. Flexibility is imparted to that process by suspending the contact material in steam or other carrier gas and adding the heavy petroleum stock at variable levels in the riser.
