ABSTRACT:
Low sulfur metallurgical coke and pitch and low sulfur, ash-free carbon suitable for electrodes are produced from sulfur-containing, non-coking or coking coals by hydrogenation of such coals in an economical cyclic system in which particulate coal, in the absence of pasting oils, is contacted with a large volume of circulating hydrogen under conditions providing a low sulfur heavy oil or oil-carbonaceous solid mixture which is then converted into the coke, pitch and/or electrode carbon. Sulfur in the coal is converted to gaseous compounds and is removed from the circulating hydrogen stream. Light oils of aromatic nature are also produced.
