Current Research:

Professor Tavlarides’ current research activities include iodine, alkyl iodides and water(substitute for tritiated water) adsorption as required for radioactive gases capture that are released in the treatment processes of spent nuclear reactor fuel waste. Studies include data acquisition of kinetic rates of adsorption and equilibrium adsorption of model gases for various adsorbents over a range of conditions, and development of kinetic and equilibrium models to describe these processes. Similar multicomponent data will also be obtained and models developed for these systems. The results will be employed in adsorption column codes to design separation facilities for capture of these and other radioactive gases such as tritium, CO2, krypton and xenon This program is ongoing through DOE NEUP funding and involves a collaborative effort with Georgia Institute of Technology, Prairie View Texas A&M, Oak Ridge National Laboratory, and Idaho National Laboratory

Other work is in progress to develop and evaluate special injectors for injection of supercritical diesel fuel at high temperatures (~ 350-400 0C) for a novel diesel engine concept and to evaluate the combustion products and efficiency of combustion using the injector. The NYSERDA support is currently closing, however, a proposal is pending with the DOE ARPA-E program. Additionally, we are studying the properties of diesel fuel and the stability of diesel fuel under these high temperature conditions. A proposal is pending for this work with National Institute of Standards and Technology to study the thermophysical and chemical properties of dieseline. Similar to this project is the process of biodiesel fuel production through transesterification reactions of vegetable oils, waste oils and algae lipids with supercritical methanol. We have determine reaction conditions for efficient production (T = 350-400 0C, P= 150-200 bar and residence time of 8-10 min) and provided economic analyses of the production facilities which show that the manufacturing costs are ~50% less than other processes for biofuel production. We are currently demonstrating the feasibility of the process with algae oil, are designing a pilot plant facility, and will be seeking support from various agencies.
