Solvent extraction of coal by a heavy oil
Patent
·
OSTI ID:5858195
Carbonaceous material, such as coal, is converted to liquid products by solvent extraction with a heavy carbonaceous liquid containing C/sub 7/H/sub 14/ insoluble material, such as a heavy asphaltene containing crude oil. The admixed solvent and solid are heated to 55 to 935/sup 0/F 500 to 1000 psig in the presence of H to liquefy the desired fraction of solid. The mixture of solvent and liquefied coal recovered as the product boils at > 650/sup 0/F, and has a reduced asphaltene content.
