Bitumen Cracking in Supercritical Water Upflow Masato Morimoto,* Yoshikazu Sugimoto, Shinya Sato, and Toshimasa Takanohashi Advanced Fuel Group, Energy Technology Research Institute, National Institute of Advanced Industrial Science and Technology, Tsukuba 305-8569, Japan ABSTRACT: Bitumen was cracked in a high-pressurized water upflow at 440 °C and 10, 25, and 30 MPa using continuous stirred tank reactor. At 30 MPa, which was the optimal dispersion condition, the highest liquid yield, lowest coke, highest conversion, and heaviest liquid products were obtained. Even at optimal conditions, all the asphaltene (AS) could not be entrained with the supercritical water (SCW) upflow; thus, the product oil contained
