SPECIFICATION Title of the Invention: PREPARATION OF CARBONACEOUS PRODUCTS Abstract of the Disclosure: Coal is dissolved in a hydrocarbon solvent, heated and purged of insolubles to form various types of solvent purified coal having different degrees of depolymerization. These various types of solvent purified coal are then coked to yield a variety of green coke products. The solvent purified coal is useful as a raw material for needle-like green coke when the value of its (N+O+S)/C atomic ratio is less than 0.0445; for coarse mosaic green coke when the value is in the range of from 0.0445 to but excluding 0.0516; for mosaic green coke when the value is in the range of from 0.0516 to but excluding 0.0584; for fine mosaic green coke when the value is in the range of from 0.0584 to but excluding 0.0645; and for glassy green coke when the value is equal to or greater than 0.0645. - 1 -
