Abstract

Two processes were studied in the period. The first was a study of oxidative desulfurization processes. Earlier research indicated that the use of copper-promoted oxidation of the organic and inorganic sulfur species in coal showed considerable promise. Initial studies utilizing CuCl{sub 2} demonstrated that the desulfurization yields were much lower than previously quoted. However, the experiments suggested that the reactant pathway showed promise and further investigations were conducted varying the solvent and replacing the Cl{sup {minus}} anion with the OH{sup {minus}} species. Ultimate analyses of these reactions are reported in addition to the experimental conditions used. Reactions using Cu(OH){sub 2}, CuCl{sub 2}, and copper cyclohexane butyrate are investigated. The second process discussed was desulfurization using selective solvation. Supercritical ethanol was used to investigate the extent of organic sulfur removal from coal. (VC)

As mentioned in the previous report, an alternate plan of attack was to try to oxidize the sulfur in coal in a nonaqueous solvent, such as DMF. Copper oxidation reactions are known to have much greater reaction rates in apolar solvents such as DMF. In this experiment the reaction solvent was 50 % v/v H{sub 2}0-DMF with 14% CuCl{sub 2} dissolved in it. The coal sample used was Illinois {number_sign}6. The reaction temperature used was 95{degrees}C and the reaction time was 17 hrs. The remaining coal solid was then sent to Blackrock Test Labs, Morgantown, WV for analysis of sulfurmore »« less

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:more »« less

During this quarter the studies on the selective desulfurization of coal were initiated. Specifically most of our efforts this quarter were place in developing selective reaction chemistries within a supercritical carbon dioxide system that would provide significant desulfurization of the organic matrix of coal. The first system of interest is the possible desulfurization of coal by oxidation with solvated cupric ions. The reaction of copper chloride with sulfur moieties in coal was first studied by Lompa-Krzymien. (As mention in the original proposal). In the case of Lompa-Krzymien`s work this reaction was claimed to yield desulfurization rates as high as 95%more »« less
