thesis / dissertation description
The Deno coal oxidation technique was investigated as a tool for the characterization of the aliphatic components of coal. This technique was applied to three high sulfur Kentucky coals:(1) No. 789673, (2) KCER 4002-Elkhorn No. 2, (3) KCER 7122-Ky. No. 12 and a low sulfur coal from Alpha Resources, Inc. Model compound investigations on toluene, ethyl benzene, propyl benzene, bibenzyl, indan and tetralin were also conducted. Different addition modes were investigated using ethyl benzene and diphenylmethane. The stability of the expected aliphatic acid products in the oxidation reagent were also investigated.The data indicated the following: Pyrite present in high sulfur coals catalyzes the decomposition of the oxidizing reagent. Complete oxidation of both coals and model compounds to CO2 and H20 was occurring. The expected aliphatic acid products were not stable in the oxidizing reagent.
