Biography

Dr Thomas L. Robl is the Associate Director for Environmental and Coal Technologies (ECT) at the University of Kentucky Center for Applied Energy Research. ECT is a multi-disciplinary research group consisting of chemists, material and civil engineers and earth scientist that conduct cross cutting research into the management and utilization of coal combustion products. The research encompasses process development for ash beneficiation, the fabrication of new low energy, low CO2 emitting construction materials including cements, concretes and polymer composites from coal by products.  He is the author of more than 150 technical reports and publications, as well as four patents. He has more than 30 years of energy research experience related to coal utilization and has been the principal investigator on projects for the U.S. Department of Energy, the National Science Foundation and NATO. He is a member of the University of Kentucky Graduate Faculty and is a Director of the American Coal Association and Co-Chairman of the World of Coal Ash International Symposium.  He received a PhD from the University of Kentucky in 1977 in Geology.

Research

Research interests:

  • Beneficiation of ponded coal combustion waste at power plants
  • Development of recovery techniques resulting in materials appropriate for use as fillers, pozzolans, and lightweight aggregates, as well as carbon suitable for reburning
  • Beneficiation of IGCC slag
  • Investigation into the presence of mercury, arsenic, and other trace elements in coal combustion by-products, and their quantitative relationship to combustion processes and the source coal itself
  • Use of ammoniated fly ash in concrete products

Expertise:

  • Management and utilization of coal combustion products
  • Process development for waste material beneficiation
  • Environmental geochemistry and analysis of water, waste water and waste leachates
  • Environmental assessment of waste disposal methodology
  • Development of, and participation in, multidisciplinary research and education programs
