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 11):
A method for in situ manufacturing a mono-cyclic ether compound, oxolane, to rejuvenate bitumen or heavy crude oils into their younger lighter crude oils so that the American Petroleum Institute (API) gravity remains high after the extracted of bitumen or heavy crude oil cools, the method comprising: using a vegetable oil made from soy, corn or other food crops, as a source material containing a minimum of 50% linoleic (18:2) fatty acids; reacting the linoleic fatty acid (18:2) with methanol an alkaline catalyst to convert to methyl linoleate; blending linoleate and methanol in a selected weight, using a ratio of 1.6:1 in one embodiment, and heating to produce oxolane; and contacting the oxolane as a solvent, with the asphaltene that resides in an above ground tank by injecting the oxolane into the feed pump, or with the asphaltene that resides in a underground deposit by injecting oxolane into the steam.
