Bitumen Cracking in Supercritical Water Upflow

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...

More Information
Summary: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 <0.5% of AS. This means that bitumen cracking in the SCW upflow was a combined process of thermal upgrading and deasphalting.
