Management of coal waste by energy recovery: mild gasification/flash pyrolysis of coal preparation wastes. Quarterly report, April-June 1986
Several modifications were made to the Mild Gasification Unit, MGU. Modifications included relocating the condensing system from the second floor to the third floor, modifying the condensing system to enable water-cooling or dry ice-cooling, installation of an equilibrium line between the char chute and the gas-exist lines, and mounting the condensing system on weigh scales to allow determination of the trend of hydrocarbon liquid production as a function of time. Six tests were conducted on the MGU. Four of the tests were shakedown tests while two of the tests were part of the final test plan. Different configurations were tried on the condensing system as well as different types of cooling. Various conditions were used during the tests including tests with bituminous and subbituminous coals, lime additive, and different residence times. Analytical data on the char and liquid products were received including boiling point distribution, /sup 1/H-NMR, LC-NMR, and ultimate and proximate analyses.
