The extraction and Rock-Eva1 pyrolysis of oil sands from Karamay and Erlian were investigated. Elemental, group and distillation analyses were carried out. Bitumen from Karamay oil sand has lower contents of resin, asphaltenes and sulfur than that from Erlian. The effects of various variables on bitumen recovery were assessed. The results indicate that hot water extraction is effective for Karamay but ineffective for Erlian. The kinetic parameters of pyrolysis were determined.

The extraction and pyrolysis of tar sand from Wadi Isal, Jordan have been investigated. Solvent type, mixing time, temperature, particle size and alkali concentration have been identi"ed as important parameters for bitumen recovery. The results show that hot water extraction is ine!ective since a sm
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 30ยฐC to 150ยฐC. The co-extracted solid par
