Modified Murnaghan equation of state applied to shock compression of silica, basalt, and dolomite

Description: An equation of state previously used by the author is developed further and applied to geologic media. The equation is of the same form as the Murnaghan equation of state, but with the elastic constant terms replaced by the cohesive energy density (internal pressure), and the exponential term given as a sum of the Gruneisen parameter and the gaseous adiabatic exponent. Data for shock compression of silica, basalt, and dolomite are analyzed according to the equation.

The Effect of Chemical Additives on the Synthesis of Ethanol

Description: The objective of this research is to elucidate the role of various chemical additives on ethanol synthesis over Rh- and Ni-based catalysts. Chemical additives used for this study will include S, P, Ag, Cu, Mn, and Na which have different electronegativities. The effect of additives on the surface state of the catalysts, heat of adsorption of reactant molecules, reaction intermediates, reaction pathways, reaction kinetics, and product distributions is/will be investigated by a series of experime… more

Enhancing Sample Preparation Capabilities for Accelerator Mass Spectrometry Radiocarbon and Radiocalcium Studies

Description: With support provided by the LLNL Accelerator Mass Spectrometry Laboratory, the UCR Radiocarbon Laboratory continued its studies involving sample pretreatment and target preparation for both AMS radiocarbon ({sup 14}C) and radiocalcium ({sup 41}Ca) involving applications to archaeologically -- and paleoanthropologically- related samples. With regard to AMS {sup 14}C-related studies, we have extended the development of a series of procedures which have, as their initial goal, the capability to c… more

Adapting an x-ray/debris shield to the cascade ICF power plant: Neutronics issues

Description: A neutronics analysis has been carried out to determine the effects on the Cascade ICF reactor concept of adding a solid-lithium x-ray and debris shield to each ICF capsule. Results indicate that tritium breeding in LiAlO{sub 2} is possible with a modest isotopic enhancement in {sup 6}Li (to 15%). The shallow-burial index is greater than 1 (indicating that deep burial may be required) if the blanket is kept in the reactor for more than 2.5 yr. Nine percent of the total thermal power is unrecove… more

Hugoniot elastic limits and compression parameters for brittle materials

Description: The physical properties of brittle materials are of interest because of the rapidly expanding use of these material in high-pressure and shock wave techology, e.g., geophysics and explosive compaction as well as military applications. These materials are characterized by unusually high sonic velocities, have large dynamic impedances and exhibit large dynamic yield strengths.

(The ocean's role in the global carbon cycle)

Description: The traveler collaborated with Dr. J. L. Sarmiento of the Program in Atmospheric Sciences, Princeton University, and Dr. U. Siegenthaler of the University of Bern in box-model studies of the potential enhancement of oceanic CO{sub 2} uptake by fertilizing the southern ocean with iron. As a result of this collaboration, a letter describing the results was submitted to the journal Nature. Sensitivity studies were carried out to gain a better understanding of the processes involved for a hypotheti… more

Innovative Clean Coal Technology (ICCT): 180 MW demonstration of advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO[sub x]) emissions from coal-fired boilers

Description: This quarterly report discusses the technical progress of a US Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) Project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO[sub x]) emissions from a coal-fired boiler. The project is being conducted at Gulf Power Company's Plant Lansing Smith Unit 2 located near Panama City, Florida. The primary objective of this demonstration is to determine the long-term effects of commerciall… more

Freeze block testing of buried waste lines

Description: An investigation was conducted to demonstrate application of freeze blocking in waste transfer lines such that a hydrostatic pressure test can be applied. A shop test was conducted on a 20-foot length, 3-inch schedule 40, carbon steel pipe using a coolant of dry ice and Freon. The positive results from these tests prompted a similar employment of the freeze block method in hydrostatic pressure testing the feed inlet leading to 241-S-101 Waste Tank. This pipeline is a 3-inch schedule 10, stainle… more

Cupola modeling research: Phase 2 (Year one), Final report

Description: Objective was to develop a mathematical model of the cupola furnace (cast iron production) in on-line and off-line process control and optimization. In Phase I, the general structure of the heat transfer, fluid flow, and chemical models were laid out, providing reasonable descriptions of cupola behavior with a one-dimensional representation. Work was also initiated on a two-dimensional model. Phase II was focused on perfecting the one-dimensional model. The contributions include these from MIT,… more

Heat exchanger-ingot casting/slicing process. Silicon sheet growth development for the large area silicon sheet task of the low cost silicon solar array project. Fifth quarterly progress report, September 25, 1976--December 16, 1976

Description: Casting experiments during the quarter were directed towards determining the maximum growth rate, characterizing the mode of heat transfer to the gaseous helium in the heat exchanger, developing a sintered crucible coating, and determining the cause of a SiC deposition on the melt stock prior to melting. Also, silicon crystal slicing tests using diamond-impregnated wire blades were continued. Results are presented and discussed. (WHK)

Nitrogen oxide abatement by distributed fuel addition

Description: Experiments were conducted to investigate the processes that influence the destruction of NO in the fuel rich stage of the reburning process. The objective is to gain a better understanding of the mechanisms that control the fate of coal nitrogen in the fuel rich zone of a combustion process. Time resolved profiles of temperature, major (CO{sub 2}, CO, H{sub 2}O, O{sub 2}, H{sub 2} and N{sub 2}), nitrogenous (NO, HCN and NH{sub 3}) and hydrocarbon (CH{sub 4} and C{sub 2}H{sub 2}) species were o… more

Nitrogen oxide abatement by distributed fuel addition

Description: A combustor has been designed in order to retard the formation of nitrogen oxides by injection of reburning fuel. The design and the rebuilding of the new combustor was completed. Several new features were incorporated in the new design so that it would last longer. The design and construction of the furnace are discussed in this report. (VC)

Extraction, separation and analysis of high sulfur coal

Description: During this quarter the studies on the selective desulfurization of coal were initiated. Specifically most of our efforts this quarter were place in developing selective reaction chemistries within a supercritical carbon dioxide system that would provide significant desulfurization of the organic matrix of coal. The first system of interest is the possible desulfurization of coal by oxidation with solvated cupric ions. The reaction of copper chloride with sulfur moieties in coal was first studi… more
