Data from six recent Rocketdyne tests using subbituminous coal and four recent Rocketdyne tests using bituminous coal were entered into the computerized data base, data from 16 recent Cities Service tests using subbituminous coal and from 48 tests using lignite coal were entered into the computerized data base. Semiempirical correlations for predicting carbon conversion efficiency and carbon selectivity to methane and ethane were fitted to the Cities Service lignite and subbituminous data. Coal type did not appear to have any significant effect on carbon conversion or carbon selectivity. The correlation developed for predicting carbon conversion for the Cities Service subbituminous tests gave results that were in good agreement with the measured conversions for the recently completed Rocketdyne subbituminous tests. Substantially higher carbon conversions were obtained in the Rocketdyne tests with bituminous coal than in the Cities Service and Rocketdyne tests with subbituminous coal at comparable operating conditions. The measured carbon conversions for recent Rocketdyne bituminous tests were from 10 to 15% lower than the measured conversions for the earlier Rocketdyne bituminous tests. Operating variable levels and size constraints were chosen for the design of a conceptual full-scale hydrogasification reactor.
