Distribution of Uranium and Other Radionuclides in Coal and Coal Combustion Products, with Discussion of Occurrences of Combustion Products in Kentucky Power Plants written by authors: James C. Hower, Shigeng Dai, Greta Eskenazy.

Abstract: Uranium and thorium are part of the mineral assemblages within coals. Uranium can also occur in organic associations, particularly in low-rank coals. While the average U concentration in coals is 2.9 ppm for low-rank coals and 1.9 ppm for bituminous and higher rank coals, high concentrations are known from certain low-rank and thin coals and from coals in areas associated with U mineralization. No high-U coals are mined for power production in the United States. Uranium and Th in coal combustion products are found in amounts more or less in proportion to their concentrations in the feed coal. Not being volatile elements, both U and Th are concentrated in the

The University of Kentucky Center for Applied Energy Research hosted a tour of 60 students from the Chinese University of Mining and Technology. The group is part of a two week Study Abroad program for the undergraduates and six faculty from CUMT (Chinese University of Mining and Technology). The UK Mining Engineering Department is working with the UK College of Business to host the group.



Summer Partnership with Kentucky State University

Kazi Javed, Associate Professor of Chemistry at Kentucky State University (KSU), has always been committed to bringing science to life for his students. This summer, he is doing just that thanks to a unique partnership with the UK Center for Applied Energy Research (CAER).


Dr. Javed, who teaches an analytical instrumentation class at KSU, is volunteering in the Biofuels and Environmental Catalysis Group here at UK CAER this summer. With a focus in the classroom on instrument design and method development, Dr. Javed is bringing KSU students to UK CAER’s lab this summer to introduce them and train them on instrumentation not available at KSU.

 

Joining Dr. Javed from KSU are four students: Ma’Kaylah Garrett, a biology student from Indianapolis, Indiana; Steven Hall, a mechanical engineering student from Frankfort, Kentucky; Andrew Lentini, a mechanical engineering student from Shelbyville, Kentucky; and Siraj Ramsey, a mechanical engineering student from Hopkinsville, Kentucky. The mechanical engineering students are taking part in KSU and UK’s joint program, where the students attend KSU for three years and UK for two years. Participants receive a bachelor’s in mathematics from KSU and a UK engineering bachelor’s degree.

 

This collaborative work was made possible thanks to National Science Foundation grants entitled “MRI: Acquisition of a Gas Chromatograph with Dual Detection Capabilities to be Used in Sustainable Energy Research” (award number 1531637) and “SusChEM: Promotion of Nickel Catalysts for the Conversion of Biomass-derived Oils to Fuel-like Hydrocarbons” (award number 1437604).

MORPHO-CHEMISTRY AND MICROSTRUCTURE OF MAGNETIC CONCENTRATES OF BOTTOM ASH SAMPLES OF THERMAL POWER PLANTS, ODISHA

Author: Subir Kumar Das, from CSIR - Institute of Minerals and Materials Technology, Bhubaneswar, India

Abstract: Magnetic particles in silico-aluminous bottom ash samples (NT-BA and HR-BA samples) of two thermal power plants of Talcher area, Odisha, India have been studied for determination of their concentration, morphology, internal structure and phase mineral composition. The amounts of magnetic concentrates in NT-BA and HR-BA samples are 25.7 and 4.03% respectively and the former particles are relatively coarse grained. In NT-BA sample, most of the magnetic particles are ideal solid spheres (ferrosphere) with diverse morphological features: smooth, skeletal, dendritic, octahedral, polygonal, granular, and spotted. The magnetic particles of HR-BA sample are fine grained, irregular to angular, mostly associated with glass matrix

The magnetite crystals occur as fine streaks, laths, lamellae and needles. Examination of the inner structure of the ferrospheres and irregular magnetic particles of concentrates of both the samples revealed that the magnetite crystals have different geometric patterns and association with different mineral phases indicating variations in crystallisation conditions in the combustion chamber. The magnetite crystals of HR-BA sample are extensively martitised. The EDS results indicated that in the magnetite, Fe is the dominant element with small amounts of Mn, Mg, Ca and Ti. These elements occur as diadochic replacement of ferrous ion in the magnetite crystal structure.

The glass coexisting with magnetite has highly variable chemical compositions mainly with respect to Si, Al and Fe; few glass particles are enriched in Fe. Detrital quartz grains are occasionally observed within the magnetic particles. The magnetite oxide crystallites in ferrospheres are derived from the decomposition and oxidation of iron-bearing minerals such as pyrite and clays minerals in feed coal during combustion in the thermal power plants.

UKCAER Researchers Receive Swagelok Training

The Biofuels and Environmental Catalysis research group - at the University of Kentucky Center for Applied Energy Research - hosted Mike Sallee from Swagelok for the 4th annual CAER Swagelok seminar. It focused on how to use tubing and tube fittings appropriately with an emphasis on safety. This seminar is very informational for staff and students alike. Many BEC staff go each time the class is offered because it is a good refresher and something new is learned. Thirteen people were in attendance this year (July 14).
