Fletcher, Ash Deposition Group ACERC Brigham Young University Provo, UT, 84602 Sponsor: Plasmatek, Inc Introduction Results High sulfur content is one of the main factors preventing pet. Coke from being widely used in industry. It was considered to add potassium carbonate (K2CO3) to the petroleum coke so that the potassium reacts with the sulfur dioxide to form potassium sulfate (K2SO4) SEM X-ray Spectra Blank pet. coke Task SO2/NOx experiment data SEM quantification Perform form combustion tests to determine the amount of SO2 reduction from burning petroleum coke/K2CO3 mixtures in near-stoichiometric amounts of air.

Coke/K2CO3 burned in O2 Pet.coke/K2CO3/air Pet.coke/K2CO3/O2 Experiment Conditions Conclusion Samples of the parent petroleum coke and the ash collected from the combustion tests were analyzed for elemental composition using the X-Ray associated with the scanning electron microscope (SEM). Although SEM is not always as quantitative as we would like, it yield meaningful results. These results confirm that the sulfur is being concentrated in the ash, in conjunction with the potassium. The nickel seems to be concentrated in the ash as well, but the vanadium concentration did not increase significantly. This may indicate some vaporization of the vanadium, or may be due to the inaccuracy of the measurement. This technique also seemed to indicate a substantial amount of copper. The source of the copper is not known, and may indicate contamination from the sampling system or SEM sample preparation system.
