ABSTRACT:
A method for destructive distillation of hydrocarbonaceous distilland is disclosed wherein a dienophile is introduced into the vaporous phase to reduce the production of non-distillable polymeric product. Specifically dienophiles available economically in large amounts such as maleic anhydride are disclosed. The introduction of additional sulfide to further reduce production of asphaltenic polymeric product is also described.
