Innovative technology demonstrations

Description: Currently, several innovative technologies are being demonstrated at Tinker Air Force Base (TAFB) to address specific problems associated with remediating two contaminated test sites at the base. Cone penetrometer testing (CPT) is a form of testing that can rapidly characterize a site. This technology was selected to evaluate its applicability in the tight clay soils and consolidated sandstone sediments found at TAFB. Directionally drilled horizontal wells have been successfully installed at th… more

Quarterly technical progress report, October 1-December 30, 1983

Description: Several new initiatives were begun in coal preparation, including a project to develop a liquid CO/sub 2/ coalescence process that will produce a superclean coal containing less than 1% ash. Another new project in this area is focusing on chemical coal cleaning for the removal of harmful trace elements, such as arsenic, lead, and zinc. Milestones were reached in both of our major electron beam flue gas cleanup projects. In the area of coal-water mixtures, our major industrial contracts are now … more

Development of a correlation between slurry oil composition and process performance. Topical report 1. Analyses of slurry recycle oils from H-Coal PDU Run 5

Description: Daily samples of the slurry recycle oil from the 30-day H-Coal PDU Run 5 (Syncrude mode, Illinois 6 coal) were analyzed by /sup 1/H-NMR spectroscopy GS/MS, and liquid chromatographic techniques. The recycle oils composition in PDU Run 5 reached an initial steady-state at about day 12, but this was upset when the hydrogen partial pressure was increased on day 20. The recycle oil composition was again approaching a steady-state by the end of the run. The distillates increased in aromaticity durin… more

Applications of Micellar Enzymology to Clean Coal Technology. [Laccase]

Description: This project is designed to develop methods for pre-combustion coal remediation by implementing recent advances in enzyme biochemistry. The novel approach of this study is incorporation of hydrophilic oxidative enzymes in reverse micelles in an organic solvent. Enzymes from commercial sources or microbial extracts are being investigated for their capacity to remove organic sulfur from coal by oxidation of the sulfur groups, splitting of C-S bonds and loss of sulfur as sulfuric acid. Dibenzothio… more

Thermophysical properties of coal liquids. Final report. [300 to 600 K]

Description: Thermophysical properties for coal-solvent slurries were determined in the range 300 to 600 K, in some cases extending to 700 K. Density, viscosity, thermal conductivity, and enthalpy were determined. A recycle solvent from the Wilsonville SRC-I plant and a KY-9 coal were used. Rheology was studied with a reciprocating cylinder viscometer designed to operate at elevated pressure and temperature. Viscous properties were found to follow the Bingham plastic model. A high-viscosity peak in the rang… more

BIO-ORGANIC CHEMISTRY QUARTERLY REPORT DEC. 1960 THROUGH FEB.1961

Description: The current interest in the subject of fiber optics has brought about, among its many achievements, the development of a new technique for measuring refractive index. An instrument designed as a light-pipe refractometer or rod photorefractometer has been described by Kapany and Pike. these authors have presented both a theoretical study of the phenomenon and experimental results arising from a prototype apparatus. The range of applicability of such a device is limited, however, by the availabil… more

SPECIFIC PROTONATION OF THE CARCINOGEN 7, 12-DIMETHYIBENZ [a]ANTHRACENE AND CHARGE LOCALIZATION IN THE a-COMPLEX

Description: In the class of the polycondensed aromatic hydrocarbons, the concept of localized charge in a {sigma}-complex, e.g., the carbonium ion formed by addition of a proton or other electrophile to an aromatic ring, has so far received experimental evidence only in the case of anthracene. The ultraviolet spectrum of this compound in sulfuric acid is similar to that of the benzhydryl cation. Ph{sub c}C{sup +}Me. This result implies the protonation of anthracene at one meso-carbon atom and the localizat… more

Fluorine for Hydrogen Exchange in the Hydrofluorobenzene Derivatives C6HxF(6-x), where x = 2, 3, 4 and 5 by Monomeric [1,2,4-(Me3C)3C5H2]2CeH; The Solid State Isomerization of [1,2,4-(Me3C)3C5H2]2Ce(2,3,4,5-C6HF4) to [1,2,4-(Me3C)3C5H2]2Ce(2,3,4,6-C6HF4)

Description: The reaction between monomeric bis(1,2,4-tri-t-butylcyclopentadienyl)cerium hydride, Cp'2CeH, and several hydrofluorobenzene derivatives is described. The aryl derivatives that are the primary products, Cp'2Ce(C6H5-xFx) where x = 1,2,3,4, are thermally stable enough to be isolated in only two cases, since all of them decompose at different rates to Cp'2CeF and a fluorobenzyne; the latter is trapped by either solvent when C6D6 is used or by a Cp'H ring when C6D12 is the solvent. … more

Chemical Kinetic Modeling of Hydrogen Combustion Limits

Description: A detailed chemical kinetic model is used to explore the flammability and detonability of hydrogen mixtures. In the case of flammability, a detailed chemical kinetic mechanism for hydrogen is coupled to the CHEMKIN Premix code to compute premixed, laminar flame speeds. The detailed chemical kinetic model reproduces flame speeds in the literature over a range of equivalence ratios, pressures and reactant temperatures. A series of calculation were performed to assess the key parameters determinin… more

Feasibility of using biological degradation for the on-sitet reatment of mixed wastes

Description: This research was conducted to investigate the feasibility of applying microbial biodegradation as a treatment technology for wastes containing radioactive elements and organic solvents (mixed wastes). In this study, we focused our efforts on the treatment of wastes generated by biomedical research as the result of purifying tritium labeled compounds by high-performance liquid chromatography (HPLC). These wastes are typically 80 percent water with 20 percent acetonitrile or methanol or a mixtur… more

Moving Beyond Pump and Treat Toward Enhanced Attenuation and Combined Remedies T-Area, Savannah River Site

Description: Groundwater beneath T-Area, a former laboratory and semiworks operation at the Department of Energy (DOE) Savannah River Site, is contaminated by chlorinated solvents (cVOCs). Since the contamination was detected in the 1980s, the cVOCs at T-Area have been treated by a combination of soil vapor extraction and groundwater pump and treat. The site has received approval to discontinue the active treatments and implement a full scale test of enhanced attenuation--an engineering and regulatory strat… more

Simulation of Flow and Transport at the Micro (Pore) Scale

Description: An important problem in porous media involves the ability of micron and submicron-sized biological particles such as viruses or bacteria to move in groundwater systems through geologic media characterized by rock or mixed gravel, clay and sand materials. Current simulation capabilities require properly upscaled (continuum) models of colloidal filtration and adsorption to augment existing theories of fluid flow and chemical transport. Practical models typically address flow and transport behavio… more

The mobile phase in coals: Its nature and modes of release: Part 2, Efforts to better define the nature and magnitude of the mobile phase: Final report

Description: Several liquefaction conditions and many extracting solvents were used in attempts to set up conditions such that, as the conditions became more severe, progressively more hexane-solubles, analyzable by GC/MS, would be released. It was hoped to identify a threshold beyond which trapped mobile phase molecules would become evident. A set of 10 hexane-soluble fractions, all obtained under various conditions from the same coal (a sample of Herrin No. 6 seam, Illinois), were subjected to analysis by… more
