F-0985-L CONVERSION OF HEAVY PETROLEUM OILS Abstract Heavy petroleum oils, such as vacuum resids and heavy fractions of tar sands and shale oil, are partially converted to more volatile hydrocarbons by mixing with light aromatic hydrocarbons and treatment of the mixture with a transalkylation catalyst, for example a Friedel-Crafts catalyst such as aluminum chloride. It is believed that the conversion is essentially a transalkylation, i.e. the resid undergoes dealkylation with concurrent alkylation of the light aromatic hydrocarbon.
