Field Test Of A Calcite Dissolution Rate Law: Fort’S Funnel Cave, Mammoth Cave National Park, J. Scott Slunder

Masters Theses & Specialist Projects

The laboratory-derived calcite dissolution rate law of Plummer et al. (1978) is the most widely used and mechanistically detailed expression currently available for predicting dissolution rates as a function of water chemistry. Such rate expressions are of great use in understanding timescales associated with limestone karst development. Little work has gone into the field testing of the rate law under natural conditions.

This work compared measured dissolution rates measured by a crystal weight loss experiment in Buffalo Creek within Fort’s Funnel Cave, which lies within a pristine, forested catchment of Mammoth Cave National Park. Continuous water chemistry sampling over the …

Coal Sulfur Forms Determination Using Thermal Analysis Methods, Bucheng Wang

Masters Theses & Specialist Projects

By optimizing parameters including temperature, reaction time, reagent concentration and pressure, the optimum conditions for the mild oxydesulfurization of coals were determined to be 150°C-200"C and 10 atmospheres oxygen in aqueous slurries of coal reacted with 1 M NH₄OH for 1.5-2 hours. The total amount of sulfur removed from -60 mesh coals ranges from 51% to 78% with a mean of 64%, while the amount of inorganic sulfur removed from the coals ranged from 66% to 91% with a mean of 77%. The amount of organic sulfur removed from the samples ranged from 36% to 50% with a …

The Development Of New Methods For Coal Sulfer Forms & Sulfur In Ash Determination, Robert Forsythe

Masters Theses & Specialist Projects

The development of new procedures to determine the amount and/or types of sulfur in coal and coal products is an ongoing process for coal scientists This development is driven by the problems and inconveniences of the current ASTM methods In this thesis, the work done at Western Kentucky University in the development of two new sulfur determination procedures will be described. The first procedure can be used as an alternative method for coal sulfur forms analysis with results comparable to the ASTM method. This procedure involves heating the coal samples at 365°C and 440°C for thirty minutes to selectively remove …

Thermal Analysis Of Bismaleimide/Graphite Fiber Composite By Tg/Ftir, Qi Zhang

Masters Theses & Specialist Projects

The purpose of this project was to study the thermal and oxidative stability of a specific polymer composite. A TG/FTIR combined technique was employed to characterize this polymer/graphite fiber composite. The polymer composite sample was decomposed in nitrogen, air, and 3% oxygen atmospheres in a Seiko thermogravimetric analyzer. The use of a gas cell Fourier-transform IR spectrometer downstream from the TGA allowed for the identification of evolved gas products.

The thermal oxidative stability (TOS) of this composite was compared to its thermal stability. Also, comparison of the TOS in different atmospheres was made. In addition, the effects of specimen geometry …

Characterization Of Combustion Profiles Of Co-Fired Coal/Biomass/Limestone Samples By Tg And Tg/Ftir, Erik Jon Hutchinson

Masters Theses & Specialist Projects

Recent concerns over declining landfill space and a renewed interest in waste-to-energy technologies have increased the possibilities of co-firing different types of fuels in fluidized bed combustion systems. Fluidized bed combustion systems are idea for co-firing because of their ease in heat conversion and ability to burn a wide range of fuels. Additionally, thermal analytical techniques can be used to screen fuel blends for the fluidized bed combustion systems at a lower cost than directly firing the fuel blends in pilot systems. Three coals, three different municipal solid wastes (MSW), one limestone were combined into nine series of binary fuel …

Examination Of Fat Oxidation Products By Ft-Nmr & Ft-Ir, De Chen

Masters Theses & Specialist Projects

Edible oils are easily oxidized when used for frying. Oxidation originates with double bonds present in unsaturated fatty acids. A new NMR method is presented which offers potential for determining the products of oil oxidation. High resolution fourier transform nuclear magnetic resonance (FT-NMR) and fourier transform infrared (FT-IR) spectroscopy have found increasing use in biochemistry. One pure fat, trioleoylglycerol, was heated at 160°C in the presence of air Samples were taken for FT-NMR and FT-IR analyses at 4, 10. 20. 25, 35, 50, 70 and 100 hours. Proton, Carbon-13 and several types of two-dimensional FT-NMR spectra were obtained using a …
