β¦ Synopsis
Centrifugation was shown to have certain advantages over solvent extraction for the separation of bitumen from oil sand for research purposes. No fractionation of the bitumen during centrifugation was detected by chemical analysis. Some limitations of the method are pointed out.

The temperature dependence of, first, the yield of bitumen extracted from oil sands and, second, of the coextracted solid particles in the bitumen was studied. Centrifugal extractions were performed in an argon (inert) atmosphere at temperatures ranging from 30Β°C to 150Β°C. The co-extracted solid par
The bitumen from the Whiterocks oil sand deposit in the Uinta Basin of eastern Utah was hydrotreated in a fixed-bed reactor to determine the extent of upgrading as a function of operating variables, including pressure (11.2-16.7 MPa), temperature (642-712 K) and liquid hourly space velocity (0.18-0.
## Abstract Important process development aspects leading to more efficient bitumen recovery from diluentβconditioned oil sands by waterβbased methods are discussed. Bitumen viscosity of 0.5β2 PaΒ·s is required at the processing temperature and can be reduced to this level by bitumen dilution with a
