Analysis of coal hydrogasification processes. Final report
Bechtel Corporation has conducted a program to investigate the operability potential and scaleup feasibility of the Cities Service, Rocketdyne, Pittsburgh Energy Research Center (PERC), and Brookhaven National Laboratory coal hydrogasification processes. A reactor model study has been performed for each of the processes, and a conceptual, full-scale hydrogasification reactor design has been generated. The entrained-downflow reactor systems operate at temperatures up to 2,000/sup 0/F and pressures up to 3,000 psi. Reactor product is primarily methane, with smaller amounts of ethane, BTX, light oils, and carbon-oxides. Bechtel has collected and analyzed bituminous, subbituminous, and lignite coal hydrogasification and hydropyrolysis data from Rocketdyne, Cities Service, PERC, and Brookhaven National Laboratory. Semiempirical correlations for predicting overall carbon conversion efficiency and carbon selectivity to gaseous products have been fitted to the data. A conceptual design of a full-scale hydrogasification reactor has been generated, on the basis of the subbituminous coal data gathered in the Cities Service and Rocketdyne reactors, together with the predictive reactor performance models fitted to the data. The hydrogasification stage has a configuration similar to the Rocketdyne reactor assembly.
