Development of improved iron Fischer-Tropsch catalysts

Description: The objective of proposed research is development of catalysts with enhanced slurry phase activity and better selectivity to fuel range products, through a more detailed understanding and systematic studies of the effects of pretreatment procedures and promoters/binders (silica) on catalyst performance.

Synergistic capture mechanisms for alkali and sulfur species from combustion

Description: An aerosol reactor system has been designed and constructed for the systematic study of the mechanisms governing the possible synergistic capture of sulfur oxide and alkalis with aluminosilicates and lime (CaO). Actual particle dynamics found in coal combustor systems can be simulated, mass balances can be closed, and the system conditions are well controlled. The collection of hot reactive aerosol flows is performed utilizing an isokinetic probe.

The Savannah River Site's Groundwater Monitoring Program

Description: The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site's (SRS) Groundwater Monitoring Program. During second quarter 1991 EPD/EMS conducted extensive sampling of monitoring wells. EPD/EMS established two sets of flagging criteria in 1986 to assist in the management of sample results. The flagging criteria do not define contamination levels; instead, they aid personnel in sample scheduling, interpretation of data, and trend identifi… more

Synergistic capture mechanisms for alkali and sulfur species from combustion

Description: Due to the generation of a wide variety of pollutants during coal combustion, research on the development of a multifunction sorbent for adsorbing SO{sub 2} and alkali compounds simultaneously is ongoing at the University of Arizona. The current work focuses on the thermodynamic behavior of the reacting system for alkali adsorption especially in gas phase. The temperature and pressure effects on sodium species and on the system are intensively investigated under the simulated flue gas compositi… more

Synergistic capture mechanisms for alkali and sulfur species from combustion

Description: The research described here is directed towards an investigation of mechanisms governing the capture of alkali metals and SO{sub 2} by injection of clay based sorbents into a combustor environment. While the species of interest are products of coal combustion, the earlier parts of these investigations will use a gas flame doped with relevant levels of Potassium, Sodium and Sulfur dioxide typical of a coal flame environment. This ensures that the particles so sampled from the combustor are from … more

An overview of the Yucca Mountain Global/Regional Climate Modeling Program

Description: The US Department of Energy (DOE) has developed a site characterization plan (SCP) to collect detailed information on geology, geohydrology, geochemistry, geoengineering, hydrology, climate, and meteorology (collectively referred to as ``geologic information``) of the Yucca Mountain site. This information will be used to determine if a mined geologic disposal system (MGDS) capable of isolating high-level radioactive waste without adverse effects to public health and safety over 10,000 years, as… more

Improved numerical methods for quantum field theory (Outstanding junior investigator award)

Description: We are developing new and more efficient numerical methods for problems in quantum field theory. Our principal goal is to achieve radical reductions in critical slowing-down. We are concentrating at present on three new families of algorithms: multi-grid Monte Carlo, Swendsen-Wang and generalized Wolff-type embedding algorithms. In addition, we are making a high-precision numerical study of the hyperscaling conjecture for the self-avoiding walk, which is closely related to the triviality proble… more
