Abstract:
The invention relates to a method of increasing the American Petroleum Institute (API) gravity of feedstocks by reacting one or more mono-cyclic ether solvents such as oxolane with the asphaltene resident in bitumen or crude oils, at an ambient or elevated temperature, and at ambient or elevated pressure, to increase the API gravity and the economic value of the bitumen or crude oil, and a method for in situ manufacturing a mono-cyclic ether, oxolane, to rejuvenate bitumen or heavy crude oils into their younger lighter crude oils by blending methyl linoleate and methanol in a ratio; heating to produce oxolane; and contacting the oxolane as a solvent with the asphaltene resident in bitumen and heavy crude oils to release not only aromatic compounds, represented by toluene, but also the paraffinic alkanes, represented by n-heptane, making the feedstocks ready for extraction, separation of sand, pipeline transport and refining.

Claim (Index 8):
The method according to  claim 1 , wherein the method is to provide the mono-cyclic ether solvent that has both a polar and a non-polar region to avoid the need for adding detergent or micelles.
