ABSTRACT:
This invention provides a method for coprocessing of heavy hydrocarbon oil and coal to achieve demetalation of the oil and liquefaction of the coal.
An essential aspect of the process is a two-stage visbreaking system in which the oil and coal are heat-treated respectively at the optimum severity for each, with little formation of coke byproduct.
