ABSTRACT:
An improved tar sands derived bitumen and coal liquification process is disclosed wherein substantial percentages of subdivided coal particles and tar sands derived bitumen liquids are mixed and then corefined with hydrogen under hydrocracking conditions, but in the absence of a separate catalyst, at a temperature range of 800.degree. to 900.degree. F. and a pressure of about 2400 psig. The resutling fluid after removal of residual solids is a suitable liquid feedstock for conventional refinery equipment to produce petroleum fractions useful as transportation and heating fuels. Preferably, a portion of the corefined bitumen-coal liquid product may be recycled for mixture with the bitumen liquid and coal. Raw or native tar sands may also be mixed with the liquid butumen and coal in the process.
