A method for treatment of the heavy hydrocarbonaceous fraction resulting from thermal cracking of high molecular-weight hydrocarbonaceous materials, which method comprises removing light hydrocarbons contained in said fraction by bringing it into contact with a bed packed with refractory inorganic particles at an elevated temperature so as to evaporate said light hydrocarbons and regenerating said refractory inorganic particles-packed bed by incinerating heavy hydrocarbonaceous materials remaining on and/or among said particles in the bed by supplying oxygen to the bed.
