ABSTRACT:

Experimental work has begun on four separate projects related to coal conversion processes. An experimental adiabatic flow reactor has been modified to study the direct digital control of exothermic multiphase reactions. The computer program controlling the reactor has been changed to reflect the equipment modifications. Two Fischer-Tropsch catalysts have been tested preliminarily. A chromatographic apparatus has been refitted to study the absorption of SO sub 2 , NO and NO sub 2 by various liquid chemicals. Amines (including triethylene tetramine), N-cyclohexyl-2-pyrrolidone, liquid membranes and stabilized liquid membranes will be tested. Tests have begun in another experimental fixed-bed flow reactor system, which uses an on-line mass spectrometer and various isotopes of carbon and hydrogen to study the mechanism of synthesis gas conversion on composite catalysts. Initial tests of this method show that the use of exp 13 C alone is insufficient. The use of both exp 13 C and D (deuterium) will be tested next. Tests in an experimental apparatus for supercritical extraction of coal with water-piperidine mixtures have been made. Results obtained with Illinois No. 6 and Bruceton bituminous coals have been compared with earlier results using Powhattan No. 5 coal. Effects of variations in the preasphaltene content of the coal and the hydrogen donor characteristic of the solvent have been found. (ERA citation 09:017953)
