ABSTRACT:
This invention provides a process which involves visbreaking of a heavy hydrocarbon oil in the presence of a suspension of coal particles of 50-2000 micron size.
The presence of the fine coal solids permits severe visbreaking conditions which increases the yield of fuel range distillate products. Coke deposition occurs on the surfaces of the coal particles rather than on the surfaces of the heater chambers.
The coal particle surfaces also serve to catalyze demetallation of the heavy oil feedstock, and to adsorb demetallation deposits.
