Observation of high-lying resonances in the H sup minus ion

Description: This dissertation reports the observation of several series of resonances, for which both electrons are in excited states, in the photodetachment cross section of H{sup {minus}}. These {sup 1}P doubly-excited states interfere with the continuum in which they are embedded, and appear as dips in the production cross section of excited neutral hydrogen. The experiment was performed by intersecting an 800 MeV H{sup {minus}} beam with a (266 nm) laser beam at varying angles; the relativistic Doppler… more

A novel process for manufacture of methanol. Progress report, March 1--May 31, 1990

Description: A bench-scale reactor is being used to conduct studies of the conversion of synthesis gas to methanol by a novel process. During the last quarter, the effect of operating parameters such as temperature, pressure, feed H{sub 2}/CO ratio and feed flow rate on the MeOH synthesis rate were investigated. The specific rate of MeOH synthesis was found to vary with gas feed rate -- an unexpected result. It is proposed that this is due to the presence of small amounts of an inhibiting agent which accumu… more

The development of precipitated iron catalysts with improved stability. Technical progress report, April 1, 1990--June 30, 1990

Description: Precipitated iron catalysts are expected to be used in the next generation of slurry reactors for the large-scale production of transportation fuels from synthesis gas. These reactors may operate at higher temperatures and lower H {sub 2}: CO ratios relative to the Sasol Arge reactor. The feasibility of iron catalysts has been demonstrated under relatively mild Arge-type conditions but not under the more severe slurry conditions. The goal of this program is to identify the chemical principles g… more

Evaluation of severe accident risks: Quantification of major input parameters: MAACS (MELCOR Accident Consequence Code System) input

Description: Estimation of offsite accident consequences is the customary final step in a probabilistic assessment of the risks of severe nuclear reactor accidents. Recently, the Nuclear Regulatory Commission reassessed the risks of severe accidents at five US power reactors (NUREG-1150). Offsite accident consequences for NUREG-1150 source terms were estimated using the MELCOR Accident Consequence Code System (MACCS). Before these calculations were performed, most MACCS input parameters were reviewed, and f… more

Slurry phase Fischer-Tropsch synthesis: Cobalt plus a water-gas shift catalyst, January 1, 1990--March 30, 1990

Description: Experiments to study cobalt-catalyzed reactions of light 1-alkenes added to synthesis gas feed have been performed. Data have been collected at 220{degrees}C, 0.45 to 1.48 MPa and a synthesis gas flow rate between 0.015 and 0.030 Nl/(gcatmin) with H{sub 2}/CO of 1.45 to 2.25. C{sub 2}H{sub 4}, C{sub 3}H{sub 6}, and C{sub 4}H{sub 8} were added to the synthesis gas feed in concentrations ranging from 0.5 to 1.2 mole% of total feed. For each material balance in which 1-alkenes were added, a materi… more

Alkali/TX{sub 2} catalysts for CO/H{sub 2} conversion to C{sub 1}-C{sub 4} alcohols. Technical progress report, December 1989--February 1990

Description: The objective of this research is to investigate and develop novel catalysts for the conversion of coal-derived synthesis gas into C{sub 1}-C{sub 4} alcohols by a highly selective process. Therefore, the variations of catalyst activity and selectivity for the synthesis of alcohols from H{sub 2}/CO {le}1 synthesis gas for a series of A/TX{sub 2} compounds, where A is a surface alkali dopant, T is a transition metal, and X is a S, Se, or Te, will be determined. The alkali component A, which is es… more

A novel process for manufacture of methanol. Progress report, December 1, 1989--February 28, 1990

Description: A bench-scale reactor is being used to conduct studies of the conversion of synthesis gas to methanol by a novel process. During the last quarter, the effect of potassium methoxide and Cu-chromite loading on the MeOH formation rate was investigated. The rate obtained with Cu-chromite was compared to that using Cu-ZnO as catalyst. Work also continued on the modification of the experimental equipment to permit on-line monitoring of liquid and gas compositions.

Spin-mapping of coal structures with ESE and ENDOR. Eighth quarterly (second annual) report

Description: A nondestructive method to determine the atomic and molecular structures present in the organic (maceral) components of whole coal and coal products has been sought for many years. This program of research is designed to address that analytical need by applying advanced electron magnetic resonance techniques to the determination of coal molecular structure. Structural information has be obtained by using the naturally occurring unpaired electrons in coal as ``observation posts`` from which to s… more

Description: We report the final results from experiment E140, a recent deep inelastic electron-deuterium and electron-iron scattering experiment at SLAC. In addition, we present the results of a combined global analysis of all SLAC deep inelastic electron-hydrogen and electron-deuterium cross section measurements between 1970 and 1983. Data from seven earlier experiments are re-radiatively corrected and normalized to experiment E140. We report extractions of R(x,Q{sup 2}) and F{sub 2}(x,Q{sup 2}) for hydro… more

Description: A batch kinetic study involving Clostridium lungdahlii in a mineral medium was carried out in order to provide baseline data for the effects of nutrients on product ratio and kinetics. The use of this minimal medium containing vitamins, minerals, select amino acids and salts showed both a lower maximum specific growth rate and a lower maximum specific uptake rate than found when using a complex medium supplemented with 0.01% yeast extract. At the same time, the product ratio was improved slight… more
