ABSTRACT:
A method for recovering valuable chemical products from heavy hydrocarbons such as tar sand or petroleum waste products is disclosed and described. Heavy hydrocarbons can be contacted with a fragmentation fluid which includes ozone and a solvent carrier. The fragmentation fluid can be provided at supercritical conditions. For example, supercritical CO2can be an effective liquid solvent carrier for ozone. During contact with the fragmentation fluid, the heavy hydrocarbons are reduced in size to form a product mixture of chemical compounds. This product mixture typically includes chemical species which are more suitable than the original heavy hydrocarbons to commercial uses and/or further separation to provide useful starting materials for a wide variety of synthesis and industrial applications.
