The purpose of this research is to perform a systematic study of the yield and distribution of products on the flash or rapid pyrolysis of various ranks of coal with non-reactive (N/sub 2/, Ar, He) and with reactive gases (H/sub 2/, CH/sub 4/, CO, CO/sub 2/, and H/sub 2/O) in an entrained flow reactor. A body of information has been obtained on the flash hydropyrolysis of coals with the use of H/sub 2/ gas. Data is in the process of being obtained with the other gases. The use of methane as a pyrolyzing gas has indicated a reaction with coal and has led to developing the process of flash methanolysis of coal. The addition of steam leads to the flash hydrolysis of coal. In addition to obtaining a better understanding of the gasification of coal, the developed process chemistry data can be used to design and evaluate advanced gasification processes. 7 figs.
