Flash hydropyrolysis of Western Kentucky No. 9 bituminous coal with catalysts. Final technical progress report
Cities Service R and D Company operated a three-inch diameter-free fall flash hydropyrolysis reactor with one to three feet variable heating zone on caking and non-caking pulverized coals. With caking coals, the reactor operated satisfactorily between temperatures of 1250-1550/sup 0/F and between 900 to 950/sup 0/F with and without catalyst additions. Non-caking coals could be treated at all ranges of temperatures with or without catalyst additions. Up to two pounds per hour of coal and four pounds per hour of hydrogen were fed into the reactor. Of the catalysts tested, zinc chloride proved most effective, but only at low temperature of about 900/sup 0/F. At temperatures of 1250 to 1450/sup 0/F, zinc chloride, as well as other catalysts, proved to be ineffective. At 1400 to 1450/sup 0/F and 1000 psig with 0.5 seconds solids residence time, about 47 percent of the carbon in caking coals were converted into useful gas and liquid products: 10 percent BTX, 7 percent light oil, 10 percent heavy oil, 27 percent total oil, 12 percent methane, 8 percent ethane and 20 percent total gas. On a maf (moisture-ash free) basis, conversion was 24 percent oil, 21 percent gas, 12 percent liquor (sour water and ammonia) and 43 percent char. These FHP liquids are superior to the COED pyrolysis liquids.
