PROCESS FOR PRODUCING TRANSPORTATION FUELS FROM OIL SANDS-DERIVED CRUDE
First Claim
1. A process for treating deasphalted crude oil extracted from oil sand, comprising:
- supplying a hydrocarbon recycle solvent stream to a contact zone of a vessel, wherein the recycle solvent has a Hansen dispersion blend of not greater than 16, a Hansen polarity blend of less than 1 and a Hansen polarity blend of less than 2;
supplying a feed stream of oil sand to the contact zone of the vessel, wherein the oil sand is comprised of at least 4 wt % total bitumen, based on total weight of the supplied oil sand;
contacting the oil sand with the hydrocarbon recycle solvent in the contact zone of the vessel to separate not greater than 80 wt % of the bitumen present on the oil sand;
removing at least a portion of the hydrocarbon solvent and the separated bitumen from the contact zone of the vessel;
separating the hydrocarbon solvent from the separated bitumen to produce the hydrocarbon recycle solvent stream and a deasphalted crude oil stream, wherein the deasphalted crude oil stream has an ASTM D7169 5% distillation point of from 400°
F. to 700°
F., an asphaltenes content of not greater than 10 wt %, a Conradson Carbon Residue (CCR) of not greater than 15 wt % and sulfur content of not greater than 4 wt %, andtreating the deasphalted crude oil stream with a hydrotreating catalyst or catalytic cracking catalyst.

Abstract
Disclosed are processes for extracting deasphalted crude oil from oil sand. Deasphalted crude oil can be extracted using a hydrocarbon recycle solvent stream having specified Hansen blend parameters, with the oil sand being contacted with the hydrocarbon recycle solvent stream in a contact zone of a vessel to separate not greater than 80 wt % of the bitumen present on the oil sand. The separated bitumen is considered a deasphalted crude oil stream, since it has an asphaltenes content substantially lower than that of the total bitumen initially present on the oil sand. The deasphalted crude oil stream can be treated using a hydrotreating catalyst or catalytic cracking catalyst to produce transportation fuel.
