REVIEW AND EVALUATION OF RESIDUE CARBONIZATION IN THE CONSOL SYNTHETIC FUEL PROCESS

摘要

Design and operating experience of the low-temperature carbonizer in the Consol Synthetic Fuel Pilot Plant at Cresap, W. Va., have been reviewed and evaluated as the first phase of a project at ORNL for bench-scale carbonization of residue from coal liquefaction processes. Solids-laden residue from the solid-liquid separation step of a coal liquefaction process may be converted into valuable liquid and gaseous products and dry, free-flowing char by low-temperature carbonization. As a result of this review, the bench-scale carbonizer at OREL will maintain a high degree of similitude with the Cresap carbonizer for proposed carbonization experiments with H-Coal vacuum distillation bottoms and with solvent extraction underflows from Solvent Refined Coal and Consol Synthetic Fuel product liquids.
