Heteronuclear probes of coal structure and reactivity. Quarterly report, July--September 1993

Description: The most exciting finding in this quarter is the quantitative removal of sulfur from Illinois No. 6 coal using PBu{sub 3}. In previous quarterly reports we described the removal of 92% sulfur by refluxing a suspension of Illinois No. 6 in PBu{sub 3} for two days. The secret for quantitative removal (98.7%, run 1 in Table I) is to place the coal sample under vacuum, then adding the PBu{sub 3} while the sample is still under vacuum and finally raising the pressure of the system to atmospheric wit… more

Production of mild gasification coproducts project. Quarterly technical progress report, [July 1, 1993--September 30, 1993]

Description: The work of producing the coproduct samples and delivering the samples of each feedstock coal, the Coal Derived Liquid (CDL) and the Simulated Process Derived Fuel (PDF) has been accomplished under Option: Item 2 of this contract. The feedstock coals were taken from four mines which are defined below. Table 1 depicts the history of the coals from the taking of samples at the mine to delivery of all samples to the designated laboratories for test, analysis and reporting.

Nuclear Structure Research. Annual Progress Report

Description: The most significant development this year has been the successful elucidation of the low-energy systematics of the very neutron-deficient Pr, Nd, Pm, and Sm isotopes. This includes an extensive set of Nilsson bandheads in {sup 133}Nd. Some serious errors in earlier decay scheme work were found. The results require some significant reassessments of mean-field calculations in this region. Part of our program continues to focus on shape coexistence and electric monopole (E0) transitions in nuclei… more
