The future of coal usage to alleviate the energy shortage depends on our ability to burn coal cleanly and to convert it to gaseous and liquid products. This paper discusses the state-of-the-art of coal conversion and reviews briefly by simplified flow sheets the major gasification and liquefaction processes. At present, technology has not advanced beyond pilot plant or demonstration stages; even the optimistic experts predict that commercial operations will not be realized before the 1980's. Hence, a large and concerted effort is needed now to implement the conversion of coal to gas and oil.
