Catalyst and process development for synthesis gas conversion to isobutylene. Quarterly report, July 1, 1993--September 30, 1993 (open access)

Catalyst and process development for synthesis gas conversion to isobutylene. Quarterly report, July 1, 1993--September 30, 1993

Trickle bed reactor experiments using precipitated and commercial zirconia resulted in the production of more C{sub 2}-C{sub 3} hydrocarbons than the fixed bed gas phase reactor when using a hydrogen to CO ratio of 1. Because of problems associated with solvent cracking the reactor temperature for the trickle bed was limited to 400{degrees}C, whereas temperatures up to 450{degrees}C had been used for the fixed bed reactors. Co-feeding H{sub 2}S with the synthesis gas resulted in reduction of C{sub 1} to C{sub 3} production rates, an increase in C{sub 5} production and an increase in the production of 3-methyl-l-butene. Zirconia prepared with Ce resulted in a highly active and selective catalyst with isobutylene production rates of 4 to 8.5 kg/(m{sup 3} cat. h) for CO conversions of 15 to 34%. Kinetic models necessary for reactor design are first order for CO and one half order for hydrogen, indicating the dissociation of hydrogen on the catalyst surface. Carbon dioxide was found to be the most abundant specie on the surface of the catalyst and retards the rate of reaction. A modification of the Anderson Schultz Flory distribution resulted in an empirical procedure for estimating product distributions.

Tributylphosphate in the In-Tank Precipitation Process Facilities (open access)

Tributylphosphate in the In-Tank Precipitation Process Facilities

A material balance investigation and evaluation of n- tributylphosphate (TBP) recycle throughout ITP and its carryover to Defense Waste Processing Facility (DWPF) was performed. Criticality and DWPF-related issues were determined to pose no adverse consequences due to TBP addition. Effects of decomposition products were also considered. Flammability of 1-butanol, a TBP decomposition product, in Tank 22 was investigated. Calculations show that Tank 22 would be ventilated with air at a rate sufficient to maintain a 1-butanol concentration (volume percent) well below 25 percent of the lower flammability limit (LFL) for 1-butanol.

Colorado School of Mines low energy nuclear physics project. Final technical progress report (open access)

Colorado School of Mines low energy nuclear physics project. Final technical progress report

This report summarizes the accomplishments of the project ``Studies of nuclear reactions at very low energies``. This project was undertaken in 1987 and completed in 1993. All but one of the major objectives of this study have been accomplished. Specifically the authors have completed their investigation of the (p,{gamma}) on light nuclei, a study of the Oppenheimer-Phillips effect, a measurements of the astrophysically interesting reaction D({alpha},{gamma}){sup 6}Li at low energies and an extension of the reaction D(d,{gamma}){sup 4}He to lower energies than previously observed. Preliminary investigation of te reaction {sup 7}Li({sup 3}He,p){sup 9}Be was begun and is continuing under a separate DOE grant. In addition to these tasks, they have completed some very interesting projects which were not included in the original proposal. These include a study of the (d,{gamma}) reactions on {sup 6}Li, {sup 7}Li and {sup 10}B and an investigation of the possibility of observing terrestrial antineutrinos from the beta decay chains of U and Th as a diagnostic of terrestrial heat flow.
