Regulation of coal polymer degradation by fungi. Quarterly report, 31 July 1997--30 September 1997

Description: During this reporting period the authors continued their investigations of how low rank coals are degraded by wood rotting fungi. Previous investigations showed that ligninolytic cultures of P. chrysosporium could decolorize soluble low rank coal macromolecule. The authors continue to investigate this phenomenon. Consistent with earlier observations they conclude that soluble coal macromolecule is decolorized in ligninolytic cultures of P. chrysosporium. To determine if this fungus can depolyme… more

Mechanisms and optimization of coal combustion. Quarterly progress report

Description: During the past quarter, protocols for pyrolysis and combustion experiments were developed. The performance of the new control algorithms was evaluated, particularly for the rapid pyrolysis experiments where heating rates ranging from 100 to 1,000 C/s were achieved. Finally, a new digital image analysis procedure was developed to detect and quantify thermal ignitions of burning coal or char particles.

Fluid Dynamics of Pressurized, Entrained Coal Gasifiers

Description: Pressurized, entrained gasification is a promising new technology for the clean and efficient combustion of coal. Its principle is to operate a coal gasifier at a high inlet gas velocity to increase the inflow of reactants, and at an elevated pressure to raise the overall efficiency of the process. Unfortunately, because of the extraordinary difficulties involved in performing measurements in hot, pressurized, high-velocity pilot plants, its fluid dynamics are largely unknown. Thus the designer… more

300 Area Process Trenches Supplemental Information to the Hanford Contingency Plan (DOE/RL-93-75)

Description: The 300 Area Process Trenches are surface impoundments which were used to receive routine discharges of nonregulated process cooling water from operations in the 300 Area and dangerous waste from several research and development laboratories and the 300 Area Fuels Fabrication process. Discharges to the trenches ceased in 1994, and they were physically isolated in 1995. Remediation of the trenches is scheduled to begin during July 1997. Currently, there are no waste management activities require… more

Speciation and structural characterization of plutonium and actinide-organic complexes in surface and ground waters. Annual progress report, September 1996--September 1997

Description: 'The authors proposed research is designed to study the association of actinides with dissolved organic complexes in subsurface waters. Actinide-humic matter associations in natural waters have been investigated previously, but they have postulated that much of the actinide binding activity may be supported by colloidal biopolymers. To investigate this, they are developing techniques to sample and identify organic constituents in groundwater, and to measure the Pu associated with different frac… more

Improved Efficiency of Miscible CO{sub 2} Floods and Enhanced Prospects for CO{sub 2} Flooding Heterogeneous Reservoirs

Description: This work will examine three major areas in which CO{sub 2} flooding can be improved: fluid and matrix interactions, conformance control/sweep efficiency, and reservoir simulation for improved oil recovery. The first full quarter of this project has been completed. We began examining synergistic affects of mixed surfactant versus single surfactant systems to enhance the properties of foams used for improving oil recovery in CO{sub 2} floods. The purpose is to reduce the concentration of surfact… more

Collaborative research: Hydrogeological-geophysical methods for subsurface site characterization. 1997 annual progress report

Description: 'In the first year of the project progress has been made in several areas which are central to the project. Development of Joint Hydrogcological-Geophysical Co-Interpretation Procedure A strong effort was invested in developing the concepts and the algorithm of the joint hydrogeological-geophysical co-interpretation approach. The reason for the concerted effort in that direction is the large amount of time the authors expect this task will take before completion, and also by the need to direct … more

Response of Zircon to Electron and Ne{Sup +} Irradiation

Description: Zircon (ZrSiO{sub 4}) is an actinide host phase in vitreous ceramic nuclear waste forms and a potential host phase for the disposition of excess weapons plutonium. In the present work, the effects of 800 and 900 keV electron and 1 MeV Ne{sup +} irradiations on the structure of single crystals of ZrSiO{sub 4} have been investigated. The microstructural evolution during the irradiations was studied in situ using a high-voltage electron microscope interfaced to an ion accelerator at Argonne Nation… more

InGaAs monolithic interconnected modules (MIM)

Description: A monolithic interconnected module (MIM) structure has been developed for thermophotovoltaic (TPV) applications. The MIM device consists of many individual InGaAs cells series-connected on a single semi-insulating (S.I.) InP substrate. An infrared (IR) back surface reflector (BSR), placed on the rear surface of the substrate, returns the unused portion of the TPV radiator output spectrum back to the emitter for recycling, thereby providing for high system efficiencies. Also, the use of a BSR ob… more

Dilute Oxygen Combustion Phase I Final Report

Description: A novel burner, in which fuel (natural gas) and oxidant (oxygen or air) are separately injected into a furnace, shows promise for achieving very low nitrogen oxide(s) (NOx) emissions for commercial furnace applications. The dilute oxygen combustion (DOC) burner achieves very low NOx through in-furnace dilution of the oxidant stream prior to combustion, resulting in low flame temperatures, thus inhibiting thermal NOx production. The results of a fundamental and applied research effort on the dev… more

High Temperature Electrochemical Polishing of H(2)S from Coal Gasification Process Streams.

Description: An advanced process for the separation of hydrogen sulfide from coal gasification streams through an electrochemical membrane is being perfected. H{sub 2}S is removed from a synthetic gas stream, split into hydrogen, which enriches the exiting syngas, and sulfur, which is condensed downstream from an inert sweep gas stream. The process allows for continuous removal of H{sub 2}S without cooling the gas stream while allowing negligible pressure loss through the separator. Moreover, the process is… more

High Temperature Electrochemical Polishing of H{sub 2}S from Coal Gasification Process Streams. Quarterly Progress Report, April 1, 1996--June 30, 1996

Description: Coal may be used to generate electrical energy by any of several processes, most of which involve combustion or gasification. Combustion in a coal-fired boiler and power generation using a steam-cycle is the conventional conversion method; however total energy conversion efficiencies for this type of process are only slightly over 30%. Integration of a gas-cycle in the process (combined cycle) may increase the total conversion efficiency to 40%. Conversion processes based on gasification offer … more
