Coal conversion processes. Quarterly report, March 13, 1984-June 12, 1984. [N-cyclohexyl-2-pyrrolidones and triethylene-tetraamine absorbents]
Experimental work is continuing on four separate projects related to coal conversion processes. The direct digital control of exothermic multiphase reactions is being studied in an experimental adiabatic flow reactor. A paper based on earlier results has been submitted for publication. The effect of step changes of important process variables on reactor performance has been determined. Various absorbents for SO/sub 2/ and NO/sub x/ are being studied. Further data on the absorption of SO/sub 2/ and NO/sub x/ by a solution of N-cyclohexyl-2-pyrrolidone (CHP) have been obtained. Data on the absorption of NO in triethylene-tetraamine has also been obtained. Characterization of liquid membranes formed experimentally have been performed; the FeCl/sub 2//CHP system will be examined first. Isotopic switching is being used to study the way in which promoters affect supported metal catalysts. Non-statistical distributions of /sup 13/C in Fischer-Tropsch products have been observed experimentally. A model for the ingrowth of /sup 13/C in ethane has been developed. A program for the study of the extraction of coal and oil shale using supercritical fluids is being carried out. The effect of stirrer speed, density and reaction time on the amount of toluene solubles and tetrahydrofuran solubles produced by supercritical extraction of Bruceton coal with toluene. 2 references, 11 figures, 6 tables.
