ABSTRACT:
The present invention discloses a process for producing a formed carbon products which comprises the steps of mixing a pitch or a pitch precursor and at least one kind of polymer becoming compatible with the pitch or the pitch precursor by heat-treating and having an aromatic ring and at least one sulfur, oxygen or nitrogen atom in its repeating unit; of heat-treating the mixture to convert it to a raw material pitch and thereafter of at least forming, infusibilizing and carbonizing and which succeeded to simplify a production apparatus and to reduce an energy comsumption by reducing an infusibilizing time without deteriorating physical properties of the carbon products.
