Data from three recent Rocketdyne tests using subbituminous coal and a recent Rocketdyne test using bituminous coal were entered into the computerized data base. Also, data from five recent Cities Service tests using subbituminous coal were entered into the data base. The correlation previously developed for predicting carbon conversion gave results that were in reasonable agreement with the measured conversions for the recently completed Rocketdyne subbituminous tests. This indicates that the Cities Service and Rocketdyne reactors behave similarly for the same coal. The measured value of carbon conversion for the Rocketdyne test using bituminous coal was much higher than the value predicted from the correlation based on subbituminous coal. Operating variable levels and size constraints were chosen for the design of a conceptual full-scale hydrogasification reactor. These levels and constraints were based on data gathered in the Cities Service and Rocketdyne reactors using subbituminous coal, together with predictive reactor performance models fitted to the data. A conceptual design was presented for a full-scale reactor facility which consists primarily of a hydrogasification stage to produce methane-rich product gas from the coal, and a steam/oxygen stage to produce hydrogen-rich product gas from the unreacted char.
