Method for producing distillable hydrocarbonaceous fuels and carbonaceous agglomerates from a heavy crude oil

Patent ·
OSTI ID:5423260
A method is disclosed for producing a distillable hydrocarbonaceous stream and carbonaceous agglomerates from a heavy crude oil by charging the crude oil and finely divided carbonaceous solids to a rotary kiln with the crude oil and carbonaceous solids being charged in a weight ratio from about 0.6 to about 1.5. The crude oil and finely divided carbonaceous solids are tumbled in the rotary kiln at a temperature from about 850/sup 0/ to about 1000/sup 0/ F for up to about 30 minutes to produce a vaporous stream and agglomerate particl containing a residual portion of the crude oil and finely divided carbonaceous solids. The agglomerate particles are separated into a product portion of a desired particle size range and a recycle portion; grinding the recycle portion to produce the finely divided carbonaceous solids and heating the finely divided carbonaceous solids prior to recycling the carbonaceous solids to mixture with the crude oil.
