This project revolves around understanding the fundamental processes involved in the catalytic removal of harmful oxygenated organics present in coal liquids. We are modelling the complex type of sulfided Mo catalyst proposed for these reactions with simple single crystal surfaces. These display a controlled range and number of reaction sites and can be extensively characterized by surface science techniques. We then investigate the reaction pathways for representative simple oxygenates upon these surfaces.

This report describes the work done by Science Applications International Corporation to study the effects of energetic particles on the microstability of a high temperature tokamak. The effects of an energetic population on ballooning modes in a large aspect ratio, shifted circular flux surface tokamak equilibrium are investigated with the newly developed gryokinetic numerical technique. The gryokinetic equations for the background ion and electron, as well as that of the energetic population are solved directly as an initial problem. The energetic particles are modeled with a slow-down distribution in energy. It is found that the ballooning mode stability of the plasma with an energetic species of increasing concentration does not differ much from an increase in the background plasma beta, except for possible energetic particle drift resonances. This result is encouraging to the idea that energetic particles such as alphas may be used to stabilize the ballooning modes in a fusion reactor.

In order to minimize solids deposition in the off-gas line between the primary film cooler and the quencher, Savannah River Laboratory (SRL) recommended earlier that a new DWPF melter off-gas jumper be built which would increase the off-gas velocity from less than 40 ft/s under the original design to at least 55 ft/s, excluding the melter air inleakage. Two design changes proposed for the new jumper were: (1) relocation of the entry point for the melter pressure control air from the current position near the quencher to near the film cooler exit, and (2) reduction of the inside diameter of the jumper from 8.33 to 7.156 inches. The objective of this study was to confirm the, optimum inside diameter (I.D.) proposed earlier and determine the upper and lower limits for the optimum, I.D. to initiate the actual design process. Based on more conservative bases for optimization used in this study, it was determined that the design limits for the new jumper I.D. is 7.15 [le] I.D. [le] 7.25 inches.

This document contains the first quarterly technical progress report for PTI's Bench-Scale Testing Project of a circuit integrating PTI's KEN-FLOTETM Column Flotation Technology and PTI's On-Line Quality Monitor Control System. The twelve-month project will involve installation of a 300 lb/hr. bench-scale testing circuit at PETC's Coal Preparation Process Research Facility (CPPRF) and testing of two bituminous coals (Upper Freeport and Pittsburgh No. 8 Seam Raw Coals). Figure 1 contains the project plan as well as the approach to completing the major tasks within the twelvemonth project. The project is broken down into three phases, which include: Phase I - Preparation: The preparation phase was performed principally at PTI's Calumet offices from October through December, 1992. It involved building of the equipment and circuitry, as well as some preliminary design and equipment testing. Phase II - ET Circuit Installation and Testing: This installation and testing phase of the project will be performed at PETC's CPPRF from January through May, 1993, and will be the major focus of the project. It will involve testing of the continuous 300 lb/hr. circuit. Phase II - Project Finalization: The project finalization phase will occur from June through September, 1993, at PTI's Calumet offices and will …

In preparation for experiments with surface modified Al{sub 2}O{sub 3} reinforcements in {beta}NiAl, diffusion bonding experiments were conducted. FP alumina fibers were prepared with ion sputtered surface films (Al{sub 2}O{sub 3}, Al, Ni) and then composited with {beta}NiAl slabs and hot pressed. After 70 thermal cycles, interfacial shear strength was measured. A roughness mechanism is proposed for the observed increased strength of the coated fibers. Creep in Ni{sub 3}Al was studied. 3 figs, 1 tab. (DLC)

The horizontal and vertical emittance as a function of momentum was measured in the accumulator while stacking with a small stack. The data suggests that the transverse emittance of the beam is blown up between the injection orbit and the stacking orbit. The technique shows promise, and should be repeated with a large stack to measure the emittance in the accumulator at a time when we have large losses.
