      Four methods to manufacture high-B.t.u. gas from coal are described:  Fischer-Tropsch hydrocarbon synthesis; pressure gasification and hydrogenation (Lurgi plant); coal hydrogenation with gas byproduct (Bergius process); underground gasification and catalytic enrichment.  Each process is illustrated by flow charts.  Economic factors are discussed.
