Extraction, separation, and analysis of high sulfur coal
- comp.
The work completed this past quarter has centered around the further study and characterization of the selective desulfurization of coal through the oxidative interaction of aqueous copper chloride. The reaction of the CuCl{sub 2} with the particular model compounds is conducted at a series of reaction times and reaction temperatures. The reaction times studied were 1, 3, 6, 12, and 24 hours. The reaction temperatures studied were 50, 130, 210, and 295{degree}C. After the reaction, the organic compounds were extracted with methylene chloride. These products were then analyzed via GC/IRD/MS and SFC/SCD (sulfur chemiluminescence detector). Model Coal Compounds reacted include: tetrahydrothiophene, methyl p-tolyl sulfide, cyclohexyl mercaptan, and thiophenol. At 130{degree}C, in addition to these compounds reacting, reactions were also detected for phenyl sulfide and benzo(b)thiophene. 14 figs.
