New generation of monitors for PAH's from synthetic fuel production

Description: A gap exists between the crude techniques available for measuring polynuclear aromatic (PNA) compounds in the workplace, and the sophisticated analytical tools used in the laboratory for a much more complete characterization of pollutants from synfuel operations such as coal, tar sand, and oil shale processing. Real-time or near-real instruments suitable for use by industrial hygienists are urgently needed to measure fugitive emissions. Several new instruments and instrumental techniques are de… more

Flash hydropyrolysis of coal (FHP)

Description: The present studies concentrate on the rapid gas phase non-catalytic hydrogenation of a non-caking coal (lignite) maximizing liquid hydrocarbon yields for distillate fuels and chemical feedstock. The features of a non-catalytic process and direct hydrogenation in one step to liquid distillates tend to improve the efficiency and reduce capital and operating costs compared to other liquefaction processes such as Fischer-Tropsch. The basis of the process is to rapidly heat pulverized lignite to el… more

Synchronous detection of laser-induced fluorescence

Description: Many toxic or carcinogenic organic molecules have large absorption and fluorescence emission cross sections and can thus be detected by laser-induced fluorescence (LIF) in liquid samples at parts-per-billion levels or better. The technique of synchronous detection of laser-induced fluorescence (SDLIF) provides a way to distinguish between the fluorescence from a toxic molecule and the fluorescence from a background substance. This is done by synchronously scanning the laser excitation and fluor… more

Coal conversion siting on coal mined lands: water quality issues

Description: The siting of new technology coal conversion facilities on land disturbed by coal mining results in both environmental benefits and unique water quality issues. Proximity to mining reduces transportation requirements and restores disrupted land to productive use. Uncertainties may exist, however, in both understanding the existing site environment and assessing the impact of the new technology. Oak Ridge National Laboratory is currently assessing the water-related impacts of proposed coal conve… more

Catalytic liquefaction by zinc chloride melts at pre-pyrolysis temperature

Description: Liquid-phase catalysts have proved effective for opening chemical linkages in subbituminous coal and capping the reactive segments with hydrogen atoms or other low-molecular-weight groups. The preferred temperature range is 275 to 325/sup 0/C (530 to 620/sup 0/F), so that the linkages are opened by controlled catalytic action rather than by thermal pyrolysis which requires appreciably higher temperatures. The best catalyst melt compositions used to date are zinc chloride with 10% water together… more

Reactivity of coals under coprocessing conditions

Description: In the recent years greater interest has developed for processes involving coal and petroleum fractions to produce distillate fuels. Coprocessing is especially attractive as a direct liquefaction process because it involves the use of heavy petroleum fractions, so both coal and heavy petroleum resids are upgraded simultaneously. The main distinction of coprocessing from other direct liquefaction processes is that coprocessing is more complex from a chemical standpoint than direct liquefaction p… more

SRC-II process

Description: Extensive laboratory and pilot plant experimental work on the Solvent Refined Coal Process has led to the development of an improved version of the process known as SRC-II. This work has shown considerable promise and plans are being made to demonstrate the SRC-II process using commercial size equipment in a 6000 T/D plant to be located near Morgantown, West Virginia. On the basis of recent economic studies, the products (both liquid and gas) from a future large-scale commercial plant are expec… more

Aromatic nitrogen compounds in fossil fuels: a potential hazard

Description: To achieve energy independence in the United States, converting coal to oil or extracting oil from shale will be required. Before commercial scale fossil fuel conversion facilities become a reality, chemical and biological studies of currently available synfuel samples derived from coal or shale are urgently needed in order to determine what the potential health problems, such as from occupational exposure, might be. Aromatic nitrogen compounds such as basic aza-arenes, neutral aza-arenes, and … more

Mass and energy balance constraints on the biological production of chemicals from coal

Description: Several organic chemicals, including methane and ethanol, may be produced by the bioprocessing of coal. This may be done either by direct microbial attack on the coal, or indirectly by the bioprocessing of solubilized coal. As in chemical liquefaction and gasification, the relative amounts of the various products that can be produced are severely constrained by mass and energy balance considerations. The main differences in biological processing are that water is a ubiquitous reactant, carbon d… more

The flash pyrolysis and methanolysis of biomass (wood) for production of ethylene, benzene and methanol

Description: The process chemistry of the flash pyrolysis of biomass (wood) with the reactive gases, H{sub 2} and CH{sub 4} and with the non-reactive gases He and N{sub 2} is being determined in a 1 in. downflow tubular reactor at pressures from 20 to 1000 psi and temperatures from 600 to 1000{degrees}C. With hydrogen, flash hydropyrolysis leads to high yields of methane and CO which can be used for SNG and methanol fuel production. With methane, flash methanolysis leads to high yields of ethylene, benzene … more

Blast induced subsidence in the craters of nuclear tests over coral

Description: The craters from high-yield nuclear tests at the Pacific Proving Grounds are very broad and shallow in comparison with the bowl-shaped craters formed in continental rock at the Nevada Test Site and elsewhere. Attempts to account for the differences quantitatively have been generally unsatisfactory. We have for the first time successfully modeled the Koa Event, a representative coral-atoll test. On the basis of plausible assumptions about the geology and about the constitutive relations for cora… more

Chemical structures and reactivities of coal as an organic natural product

Description: Some chemical reactions involved in coal liquefaction have been studied using carbon 14 labelled compounds and nuclear magnetic resonance. On the basis of these studies it is concluded that the role of tetralin during coal conversion is (1) to act as a dispersion vehicle; (2) to supply hydrogen radicals, when needed, to trap coal radicals, and (3) in a very minor way to undergo intermolecular reaction with the coal through making and breaking of C--C (and possibly other) bonds. As a result of o… more
