摘要：A process for preparing a carbon product, which comprises: (a) mixing

hydrocarbon material derived from coal with a hydrocarbon solvent having a boiling pointor a distillation temperature for 95 vol % of the solvent less than 350° C. and a B.M.C.I.value of 5 to 70, the value being defined as: B.M.C.I.=48,640/k+473.7S-456.8, wherein k isthe average boiling point (°K) and S is the specific gravity at 60° F. , (b) separatinginsoluble material which settles from the resulting mixture upon standing, (c) removingby distillation at least a portion of said solvent from the insoluble matter free mixture,(d) coking the residue obtained after distillation, thereby forming an acicular, green coke,(e) calcining the acicular green coke, thereby obtaining an acicular calcined coke having apore volume of more than 40+10.sup.-3 cc/g, and (f) blending the acicular calcined cokewith a binder, shaping the blend and graphitizing the blend at a high temperature.
