Visbreaking of Chinese Oil Sand Bitumen.

Thermal visbreaking of inner Mongolia oil sand bitumen was conducted at several temperatures for different lengths of time in the laboratory. The viscosity of the thermally-treated oil was reduced dramatically with thermal treatment under the condition of adding 0.3 wt% anti-coking agent, the oil sand bitumen reacting at 410°C and 45 min. The kinematic viscosity (100°C) of visbreaking oil is reduced to 138.25 mm2·s-1 and the qualities of it are conformed to 7# Chinese Standard for Fuel Oil, which can directly be regarded as product.
