Characteristics of American coals in relation to their conversion into clean energy fuels. Quarterly technical progress report, July--September 1975

Description: Twenty-one coal samples have been collected and characterized. Sixty coals have been provided to other agencies at their request. The capability of controlling coal characteristics during preparation is being developed: large variations in volatile content occur within a given raw coal but, by controlling the preparation, a uniform product with the devised specifications can be produced. Studies have begun on the suitability of various coals and cokes for use in pressurized fixed bed gasifiers.… more

Role of Non-Ferrous Coal Minerals and by-Product Metallic Wastes in Coal Liquefaction. Technical Progress Report, 1 March 1980-31 May 1980

Description: This report describes work done in a study of the role of coal minerals and by-product metallic wastes in coal liquefaction. The thermal behavior of various minerals and metallic by-product wastes was evaluated by thermal gravimetric analysis and differential thermal analysis in the presence of hydrogen, nitrogen, and air. The CPDU was operated for 220 hours to obtain baseline data and provide information on the catalytic activity of Robena pyrite in solvent hydrogenation and coal liquefaction.… more

Laboratory evaluation of high-temperature sulfur removal sorbents for direct coal-fired turbines: Final report

Description: Direct coal-fired turbine concepts currently being developed require substantial levels of sulfur removal from high-temperature gas streams. Calcium-based sorbents, limestones, dolomites, limes and lime hydrates, are capable of sulfur removal in direct coal-fired turbine combustor environments at temperature up to 1200/degree/C. Two types of desulfurizer processes are considered in this report using calcium- based sorbents: fluidized bed desulfurizer using coarse sorbent particles (300-1000 ..m… more

Coal power and combustion. Quarterly report, January--March 1977

Description: ERDA's coal combustion and power program has focused on two major areas: Direct combustion of coal and advanced power systems. Efforts in the area of direct combustion are concentrated on: Development of atmospheric and pressurized systems capable of burning high-sulfur coal of all rank and quality in fluidized-bed combustors; development of advanced technology power systems to generate power more economically than present technology permits while using medium- and high-sulfur coal in an enviro… more

Scaled-up testing of alternative trapping agents for radioactive constituents in plant vent streams

Description: Radioactive discharges from the Portsmouth Gaseous Diffusion Plant vent streams are in compliance with present standards specifying radiation limits. Regulatory trends have become increasingly restrictive on the maximum permissible dose to a member of the public. This could mean more stringent controls for radioactive emissions in the future. Fixed bed activated alumina (Al/sub 2/O/sub 3/) trapping is currently the principal method of limiting plant vent stream emissions of technetium and urani… more

Modeling of Integrated Environmental Control Systems for Coal-Fired Power Plants Quarterly Report: June-September 1989

Description: The general goal of this research project is to enhance, and transfer to DOE, a new computer simulation model for analyzing the performance and cost of environmental control systems for coal-fired power plants. Systems utilizing pre-combustion, combustion, or post-combustion control methods, individually or in combination, may be considered. A unique capability of this model is the probabilistic representation of uncertainty in model input parameters. This stochastic simulation capability allow… more

Sorption coefficients for radionuclides on samples from the water-bearing Magenta and Culebra members of the Rustler Formation

Description: The sorbing characteristics of samples from the Magenta and Culebra dolomites of the Rustler Formation (which overlie the proposed site for the Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico) for various radionuclides have been studied. Core samples extracted from various depths and boreholes within a given formation were selected to provide a cross section of materials which are present in the formations. They varied in composition from pure dolomite to nearly pure anhydrite. Th… more

Comparative analyses for selected clean coal technologies in the international marketplace

Description: Clean coal technologies (CCTs) are being demonstrated in research and development programs under public and private sponsorship. Many of these technologies could be marketed internationally. To explore the scope of these international opportunities and to match particular technologies with markets appearing to have high potential, a study was undertaken that focused on seven representative countries: Italy, Japan, Morocco, Turkey, Pakistan, the Peoples' Republic of China, and Poland. The result… more
