Process development studies on the bioconversion of cellulose and production of ethanol

Description: Preliminary studies show minimal conversion of wood by sulfur dioxide at pressures of 38 psi at room temperature. Evaluation studies of Rut-C-30 and Rut-L-5 Trichoderma viride strains were compared. Studies on the continuous production system by manipulating temperature, pH, Tween 80 level substrate concentration, and dilution rate were performed. The known major components of cellulases were characterized. Studies on the reduction of the cost of producing sugar from corn stover were performed.… more

Economic assessment of using nonmetallic materials in the direct utilization of geothermal energy. Final report

Description: The cost effectiveness of nonmetallic materials in three direct-use geothermal applications was assessed. An extensive review of the available literature was conducted in order to ascertain those processes for which sufficient design and cost data had been published to permit this economic assessment to be made. Only three such processes could be found and they are discussed.

Soil loss and leaching, habitat destruction, land and water demand in energy-crop monoculture: some quantitative limits

Description: The environmental impacts of growing biomass for energy, especially for liquid automotive fuels, are potentially large. They are sensitive to the low power production per unit area (high land requirement) and to net energy balances. Initial quantitative estimates were made for impacts per unit power within several classes of impacts, and conversely, for limits to power produced if one avoids worst-class impacts. The following types of biomass energy technologies are considered: ethanol and meth… more

Mechanism and kinetics of mineral absorption by plants. Annual progress report, October 1, 1965-September 30, 1966

Description: Plant nutrition was studied as a relation between aerobic respiration and ion uptake in barley. Potassium, chlorine, lithium, sodium, calcium, sulfates, and bicarbonates were studied by root absorption in varying concentrations of carbon dioxide atmospheres. (PSB)

Health and Safety Laboratory environmental quarterly, March 1, 1977--June 1, 1977. [Air pollution in environs of Cu smelter and fallout radionuclides in food chains]

Description: This report presents current information from the HASL environmental programs, The Technical University of Wroclaw, Poland, and the Radiological and Environmental Research Division of Argonne National Laboratory. The initial section consists of interpretive reports and notes on environmental levels of lead and mercury in the area of a copper smelter, radionuclide uptake by cultivated dusts in crops, and fallout strontium-90 in diet through 1976. Subsequent sections include tabulations of radion… more

Chemical, biomedical and ecological studies of SRC-I materials from the Fort Lewis Pilot Plant: a status report

Description: This document discusses studies performed with solvent refined coal (SRC) materials obtained from the Fort Lewis Pilot Plant during operation in the SRC-I mode. The development of analytical methodology is presented as well as results obtained from the application of these methods to light oil (LO), wash solvent (WS) and process solvent (PS). Results of cellular and animal studies with LO, WS and PS are included, along with a description of methods for the generation and characterization of LO … more

Stack released plutonium in the environment of a nuclear fuel reprocessing facility. [Savannah River Plant]

Description: Chemical separations facilities at the Savannah River Plant have released very small quantities of plutonium to the environment since 1955. Characterization studies of airborne particulates from the process stack show that the plutonium is nearly always attached to nonradioactive particles. The geometric mean diameter of plutonium-bearing particulates in the stack gas is 5.43 ..mu..m. Most of the particles contain less than 10/sup -15/ Ci of /sup 239/Pu. Studies with cascade impactors 1.1 m abo… more
