摘要

This report is a detailed summary of the experimental program designed to develop a more efficient reactor for laboratory studies of the Solvent Refined Coal Process and to bring this into correlation with pilot plant reactors. The purpose of the studies at the beginning of the period was the development of procedures for working with solvent recycle techniques to bring this material into steady state composition with regard to the process conditions and the coal being studied. Following this,studies with various reactor configurations were done to bring reaction rates in the laboratory reactor into correlation with the reactor at Fort Lewis. In addition, a considerable amount of work was done to develop process variations which involved use of unfiltered coal solution and various amounts of distilled solvent or filtrate in place of distilled solvent in the SRC process. It was shown that these techniques could be used to convert more of the organic material in coal to distillable liquids and gases. Such conversions can be done without addition of catalyst for coals which contain sufficient pyrite. Test runs were made with bituminous coals from Kentucky and Illinois. (ERA citation 04:012061)
