Now that the depletion of fossil fuels such as conventional oil is a matter of world concern, it is essential to develop an efficient method of utilizing unconventional heavy oil. To upgrade the heavy oil such as oil sand bitumen efficiently, it is important to suppress excessive polymerization and decomposition of light oil produced by the cracking of heavy oil. To suppress such secondary reactions, in this study, we have proposed a cracking method in which light oil produced by the cracking of heavy oil is instantly carried away from the reaction system. Cracking behavior of vacuum residue from an oil sand bitumen in a flowing stream of either nitrogen or super critical fluid(water or n-pentane)was examined as one of the methods to realize the concept. It was found that the method increased the yield of light oil significantly by minimizing the formation of light hydrocarbon gas and coke.
