Abstract
A method for sequentially co-processing heavy hydrocarbon materials and carbonaceous materials comprising first subjecting the heavy hydrocarbon material in the presence of a disposable metal catalyst to produce and separate therefrom a first distillate stream and a first non-distillable effluent stream containing the disposable metal catalyst. The first non-distillable effluent stream then is mixed with the carbonaceous material and the mixture subjected to liquefaction conditions in the presence of said disposable metal catalyst. The liquefaction product then is subjected through the use of sequential fractionation and critical solvent extraction processing steps to separate and recover various heavy hydrocarbon and carbonaceous-derived light hydrocarbon liquid products therefrom.
