Baseline Mapping Study of the Steed Pond Aquifer and Crouch Branch Confining Unit Beneath A/M Area, Savannah River Site, Aiken, South Carolina

Description: This report presents the results of a baseline mapping project conducted for the Environmental Restoration Department at Savannah River Site. The purpose of this report is to map the distribution of mud (clay and silt-sized material) within each hydrogeologic unit from the surface down to the top of the Crouch Branch aquifer beneath the A/M Area. The distribution of mud layers and variations in the percentage of clay and silt within the strata is extremely important in order to fully characteri… more

Studies of electrolyte penetration in carbon anodes by NMR techniques.

Description: A toroid cavity nuclear magnetic resonance (NMR) detector capable of recording radial concentration profiles, diffusion constants, and displacements of charge carriers was employed to investigate the lithium ion distribution in an electrochemical cell containing a carbonaceous material synthesized from pyrene and pillared clays as inorganic templates. A carbon rod was used in a control experiment to assign the Li{sup +} spectrum and to calibrate the one dimensional radial images.

The impact of leachate from clean coal technology waste on the stability of clay and synthetic liners. Topical report, March 1, 1995--March 31, 1996

Description: This project was developed to provide design criteria for landfill disposal sites used for sludges such as those generated using the Clean Coal Technologies (CCT) tested at the Public Service Company of Colorado`s Arapahoe Power Plant. The CCT wastes used were produced at the Arapahoe Plant Unit No. 4, which was equipped with the integrated dry NO{sub x}/SO{sub 2} emissions control system installed under the Clean Coal Technology Program. The investigation emphasized the potential impact of cle… more

PILLARED CLAYS AS SUPERIOR CATALYSTS FOR SELECTIVE CATALYTIC REDUCTION OF NITRIC OXIDE

Description: Selective catalytic reduction (SCR) of NO{sub x} by hydrocarbons was investigated on Pt doped MCM-41 and copper ion and/or cerium ion-exchanged Al-MCM-41 in the presence of excess oxygen. It was found that Pt/MCM-41 provided the highest specific NO reduction rates as compared with other Pt doped catalysts reported in the literature, such as Pt/Al{sub 2}O{sub 3} and Pt/ZSM-5. For different hydrocarbons, the catalytic activity decreased according to the sequence of C{sub 3}H{sub 6} {approx} C{sub… more
