The Evaluation of Oil Sand Bitumen Produced From Inner Mongolia

摘要

On the basis of an analysis, the bitumen produced from InnerMongolia oil sand belongs to a kind of sour naphthenic based oil with the properties of high density (rho(20) = 0. 9996 g.cm(-3)), high viscosity (nu(100) = 1553/(mm(2).sec(-1))), rich resin, and asphalt. After a series of fractions is cut by true boiling distillation (TBP) SBD-beta instrument and analyzed by corresponding instruments, the processing scheme of tar sand bitumen is proposed. The initial boiling point is 281 degrees C, and the yield of diesel, lube oil, and residual oil is 4.54%, 16.73%, and 38.06%, respectively.
