Summary
Coal-processing experiments and calculations continue to contribute to in situ coal gasification process design. Coal pyrolysis data were fit to analytical models. Chars made from Felix No. 2 and Wyodak coal appear to be very reactive to steam and CO/sub 2/, and are particularly favorable for gasification. Coal-bed gasification modeling continued. Design of a coal igniter is described. A summary reviews the extensive Russian effort in underground coal gasification. Such a review is very important to all underground coal gasification projects as only the Russians have demonstrated control of in situ coal gasification on a large scale. Their systems for both flat-lying and steeply dipping beds were successful technically, although the economics are difficult to derive from the Russian reports. The Soviet systems and some design principles are described. Finally, plans for control and disposal of gaseous and liquid pollutants from planned, LLL gasification experiments are outlined. (auth)
