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 13):
The method for manufacturing oxolane according to  claim 11 , wherein prior to injection upstream of the feed pump to above ground storage tanks that contain heavy crude or bitumen, the oxolane is produced by mixing methyl linoleate and methanol, at a volumetric ratio of 1.6 to 1, at a temperature of 60\u00b0 C. and pressure of 1 bars (15 psi), and is tested to a Kauri-Butanol solvent value of up to 850, and wherein the produced oxolane increases the API gravity of the crude oil by contacting the reaction product with the asphaltene that resides in the tank.
