Flash Pyrolysis of Coal with Reactive and Non-Reactive Gases.

摘要

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. (ERA citation 10:043616)
