Abstract
An integrated process for the production of fuels from tar sands in which bitumen is recovered from the tar sand by a hot-water separation step, recovered bitumen is converted in a hydroconversion step to gaseous and liquid fuels, carbonaceous residue from the bitumen conversion step is gasified with oxygen to produce synthesis gas, hot synthesis gas from the gasification step is water washed, hot water from the water wash step provides hot water for the separation step, and synthesis gas from the gasification step provides hydrogen for the bitumen conversion step. Soot recovered from the synthesis gas in the water wash step is transferred to the bitumen in the separation step and ultimately consumed in the process. Water contaminants from the tar sand separation step are largely eliminated in the gasification step.
