Flash pyrolysis of coal indicates increasing yield of gaseous hydrocarbons with gas film heat transfer coefficient progressing, for the inert gases, from Ar to N/sub 2/ to He and, for the reactive gases, from CO to CH/sub 4/ to H/sub 2/. The flash methanolysis of coal with methane gas indicates increasing ethylene and benzene yields with CH/sub 4//coal ratio and with He and N/sub 2/ dilution. The mechanism for the enhanced yield appears to be by a coal free-radical reaction with methane. 4 refs., 4 figs.
