The purposes of this project are: to independently confirm and possibly to improve the organic sulfur removal from Illinois coals with the PCE process developed by the Midwest Ore Processing Co. (MWOPC), to verify the forms-of-sulfur determination using the ASTM method for evaluation of the PCE process, and to develop a dechlorination procedure to remove excess PCE from the PCE-treated coal. The objectives for the second year are: to verify the possible effects of PCE treatment on coal-derived FeS2, FeSO4, and Fe2(SO4)3 on ASTM coal analysis, to investigate the behavior of sulfur during oxidation and PCE desulfurization using the isotopically signatured coal sample, to investigate the effects of conditions and/or reagents on the oxidation of the organic-sulfur-model compounds, to evaluate the extended oxidation condition on the organic sulfur removal by PCE desulfurization, and to study other innovative pretreatment processes for the removal of organic sulfur from coal under mild conditions.
This report reviews the seventh quarter progress of a two year project to examine the chemical environment of organic sulfur in the polymeric matrix of Illinois coal by laser desorption ion trap mass spectrometry. This project is attempting to develop new laser desorption-ionization schemes for coal which preserve the polymeric matrix. From work this quarter, we have concluded that ultraviolet matrix assisted laser desorption is not an appropriate method to volatilize high molecular weight material extracted from coal. However, we have found that direct 355 nm laser desorption of neat samples of pyridine extracts from Illinois No. 6 coal gives what appears to be intact molecular ions. Direct laser desorption of the extract using both IR and UV wavelengths produces a distribution of ions between 150 and 1500 amu, with a peak near 500 amu. Work is continuing into the final quarter of this project to obtain such spectra from separated coal macerals and from various other coals.
The purpose of this project are to independently confirm and possibly to improve the organic sulfur removal from Illinois coals with the PCE process developed by the Midwest Ore Processing Co.(MWOPC), to verify the forms-of-sulfur determination using the ASTM method for evaluation of the PCE process, and to develop a dechlorination procedure to remove excess PCE from the PCE-treated coal. The objectives for year-2 study are to verify the possible effect of PCE treatment on coal-derived FeS2, FeSO4, and Fe2(SO4)3 on ASTM coal analysis, to investigate the behavior of sulfur during oxidation and PCE desulfurization using the isotopically signatured coal sample to investigate the proprietary reagent on the oxidation of the organic sulfur model compounds with and without additives, to evaluate this new oxidation on the organic sulfur removal by PCE desulfurization, and to study other innovative pretreatment processes for the removal of organic sulfur from coal under mild conditions. Oxidation study on the organosulfur model compounds alone was completed in first quarter. The oxidation reactions were repeated on the organosulfur model compounds with the presence of hydrocarbon additives. These additives are known to easily produce hydroperoxides during air oxidation. Analysis of the reaction products is in progress.
One important goal of this project is the development of methods to analyze the Very High Frequency Electron Paramagnetic Resonance (VHF EPR) spectra from Illinois coals in order to determine the concentration of organic sulfur in them. In this third Quarter, the axially symmetric model for the simulation of VHF EPR coal spectra was refined for routine quantitative percent sulfur determination. The computer modeling technique which we have developed makes use of a sophisticated multi-dimensional simplex strategy for optimization. The percent sulfur determined from VHF-EPR of sporinite, vitrinite, and two blends of these macerals (from Illinois Herrin No. 6) show excellent linear correlation with far less reliable, time consuming, and difficult techniques.
This Quarterly Technical Progress Report is required under U.S. Department of Energy (DOE) Cooperative Agreement, Section XV, {open_quotes}Reporting Requirements{close_quotes} and Attachment C, {open_quotes}Federal Assistance Reporting Checklist{close_quotes}. It covers the period of October 1, 1994 through September 30, 1995. The primary objective of the HCCP is to conduct a cost-sharing project that will demonstrate a new power plant design which features innovative integration of an advanced combustor and heat recovery system coupled with both high and low temperature emission control processes. The parties anticipate that if the demonstration project is successful, the technology could become commercialized in the near term and will be capable of (1) achieving significant reductions in the emissions of sulfur dioxide and the oxides of nitrogen from existing facilities to minimize environmental impacts such as transboundary and interstate pollution and/or (2) providing for future energy needs in an environmentally acceptable manner. The primary equipment elements comprising this new power plant design includes entrained combustion systems coupled with a boiler which will produce low NOx levels, function as a limestone calciner and first stage SO2 remover in addition to its heat recovery function; a single spray dryer absorber vessel for second stage sulfur removal; a baghouse for third stage sulfur and particulate removal; and a lime activation system which recovers unused reagent from particulate collected in the baghouse. The emission levels Of SO2, NOx, and particulate to be demonstrated are expected to be better than the federal New Source Performance Standards (NSPS).
