Effect of pretreating of host oil on coprocessing

Description: The principal objective of this research is to determine the role host petroleum-derived oils (1000[degrees]F+), as well as that of catalytically treated host oils, play when used as liquefaction solvents in coprocessing with coal. The host oils will be extensively characterized and then pretreated in a number of ways which involve catalytic reactions such as hydrogenation, hydrocracking, isomerization, and dehydrogenation. The pretreated oils win then be characterized. The effects of the host … more

Corrosion fatigue of iron-chromium-nickel alloys: Fracture mechanics, microstructure and chemistry

Description: Phase transformation and cracking during RT aging of charged, high-purity Fe18Cr12Ni alloy and commerical 304 ss were examined; results show that [epsilon]* (hcp) hydride formed on Fe18Cr12Ni upon charging, and it decomposed rapidly to form first [epsilon] and then [alpha]' martensite. Morphology of fracture surfaces of Fe18Cr12Ni produced by corrosion fatigue in NaCl solutions and in hydrogen was found to be identical. Effort was made to examine the approaches and methodologies used in service… more

Quasi-elastic neutron scattering studies of protein dynamics

Description: Results that shed new light on the study of protein dynamics were obtained by quasi-elastic neutron scattering. The triple axis instrument H-9 supplied by the cold source was used to perform a detailed study of the quasi-elastic spectrum and the Debye-Waller factor for trypsin in powder form, in solution, and in crystals. A preliminary study of myoglobin crystals was also done. A new way to view the results of quasi-elastic scattering experiments is sketched, and the data on trypsin are present… more

[Oxygenated octane enhancers: Syngas to isobutylene]. Technical progress report No. 8, January 1, 1993--March 31, 1993

Description: The goal of this program is to develop a catalyst and a process for the conversion of syngas to isobutylene. However, due to the low conversion and selectivity generally experienced by the industry in direct conversion of syngas to isobutylene, indirect conversion via branched C{sub 4} alcohol intermediates is being explored. The objectives of the current program are to develop a catalyst and process for the conversion of syngas to isobutanol and to evaluate the commercial potential of the new … more

Magnetic field effects on endcap EM calorimetry in SDC

Description: The SDC calorimeter will be immersed in a strong magnetic field in the endcap region because of the solenoid which supplies the SDC tracking field. This flux must be returned through the endcap region of the electromagnetic (EM) and hadronic (HAD) calorimeters. Since magnetic fields are known to induce changes in the light output of plastic scintillator, the endcap will need to be recalibrated once the solenoid is energized. In addition, gradients in the field will create nonuniformities in the… more

Development of an extraction process for removal of heteroatoms from coal liquids. Technical progress report No. 6, 1 July, 1993--30 September, 1993

Description: The objective of this contract is to develop a CO{sub 2}-water extraction process for the removal of heteroatoms from coal-derived naphtha, diesel, and jet fuel. Coal liquids are characterized by their high content of heteroatoms. Conventional techniques could remove the heteroatoms from coal liquids, but at a high hydrogen consumption and at a high cost. A successful development of the CO{sub 2}-water extraction process will increase the environmental acceptability of coal liquids and reduce t… more

Chemical compatibility of DWPF canistered waste forms. Revision 1

Description: The Waste Acceptance Preliminary Specifications (WAPS) require that the contents of the canistered waste form are compatible with one another and the stainless steel canister. The canistered waste form is a closed system comprised of a stainless steel vessel containing waste glass, air, and condensate. This system will experience a radiation field and an elevated temperature due to radionuclide decay. This report discusses possible chemical reactions, radiation interactions, and corrosive react… more

Tevatron reverse injection

Description: In the new injection scenario antiprotons are injected onto a helical orbit in the Tevatron in order to avoid the detrimental effects of the beam-beam interaction at 150 GeV. The new scenario required changes in the tuning procedure. Antiprotons are too precious to be used for tuning, therefore the antiproton injection line has to be tuned with protons by reverse injecting them from the Tevatron into the Main Pang (MR). Previously, the reverse injection was performed in one supercycle. One batc… more

Development of a membrane-based process for the treatment of oily waste waters. [Quarterly] report, December 5, 1992--March 4, 1993

Description: This is the fourth quarterly report covering December 5, 1992, to March 4, 1993. The overall goal of this program is to develop a system based on reverse osmosis (RO) membranes that can treat oily water economically. This system will be based on the use of thin-film-composite (TFC) membranes that consist of a selective coating placed on a solvent-resistant hollow-fiber support. For this program, we plan to develop solvent-resistant hollow-fiber supports and coat them with a ``loose RO`` coating… more

US energy industry financial developments, 1993 first quarter

Description: Net income for 259 energy companies-- including, 20 major US petroleum companies-- rose 38 percent between the first quarter of 1992 and the first quarter of 1993. An increased level of economic activity, along with colder weather, helped lift the demand for natural gas. crude oil, coal, and electricity. The sharp rise in the domestic price of natural gas at the wellhead relative to the year-ago quarter was the most significant development in US energy during the first quarter. As a consequence… more

Inhibition of retrogressive reactions in coal/petroleum co-processing. Final technical report

Description: The objective of this study was to examine the processes in coal/petroleum coprocessing systems which led to coke formation. Specifically, the interactions between the petroleum residue and coal, leading to retrogressive products, were investigated. Five coals were reacted with five model compounds in order to investigate the coal conversions in a variety of solvents and to determine the role of the solvent in promoting or inhibiting coal conversion. The selected model compounds range from para… more

Shale oil value enhancement research. First quarterly technical progress report, March 1, 1993--May 31, 1993

Description: Concurrent progress is being made in all key areas, namely, separation, characterization and market assessment. The market area, not one of our traditionally strong areas, has been going better than expected. We believe this is due mainly to the emerging interest in new and unconventional materials. The characterization work has been progressing solidly with the fundamental Z-BASIC correlations providing information not heretofore available in the chemical literature. Our agreement with Hewlett… more

High temperature alkali corrosion of ceramics in coal gas. Quarterly progress report No. 7, March 1, 1993--June 1, 1993

Description: Corrosion kinetics of SiC were investigated from 950 to 1100C at 0.63 vol% alkali vapor concentration. Corrosion rate in alkali is 10{sup 4} to 10{sup 5} times faster than oxidation rate of SiC in air. Activation energy of the alkali corrosion is 406 kj/mol, indicating a high sensitivity to temperature changes. Overall reaction appears to be controlled by the oxidation of SiC. The alkali corrosion kinetics of Si{sub 3}N{sub 4} from 950 to 1050{degrees}C were also examined in the same atmosphere… more
