Analysis of coal hydrogasification processes. Monthly technical progress report, 1 January--31 January 1978
Data from four recent Rocketdyne hydropyrolysis tests with subbituminous coal and 24 recent Rocketdyne partial liquefaction tests with bituminous coal were entered into the computerized data base. The Rocketdyne data base was expanded to include calculated values for carbon selectivity to methane, ethane, and BTX. The PERC data base was also expanded to include calculated values for gas velocity, gas residence time, and carbon selectivity to gas, methane, and ethane. The semiempirical correlation for predicting carbon conversion efficiency was fitted to the Cities Service and Rocketdyne Subbituminous coal data. The analysis showed that the Cities Service bench-scale reactor and the Rocketdyne 1/4-ton/hr reactor give similar carbon conversions under comparable operating conditions. An improved semiempirical correlation was presented for predicting overall carbon conversion, which also accounts for thermodynamic equilibrium between the coal and reaction products.
