Abstract
The extraction and Rock-Eval 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.
