Reactivity of young chars via energetic distribution measurements

Description: We have developed what we believe to be the very first a priori prediction technique for the gasification reactivity of coal char. With this method the gasification reactivity of a coal char as function of temperature can be predicted from a single temperature programmed desorption (TPD) experiment following mild gasification at a single temperature (Calo et al., 1989; Hall and Calo, 1990a). This approach has been demonstrated for C0{sub 2} gasification of coal chars where the gasification reac… more

Release of ammonia from HAN-type PHA

Description: A preliminary design basis for ammonia scrubbers in the DWPF has been issued. This design basis is based on a theoretical model of ammonia evolution from the SRAT, SME and RCT. It is desirable to acquire actual process data on ammonia evolution prior to performing detailed design of scrubbers for DWPF. The evolution of ammonia from the SRAT and SME in the Integrated DWPF Melter System (IDMS) was investigated during the HM4 run. In this run, Precipitate Hydrolysis Aqueous (PHA), which was made i… more

Synthesis of octane enhancers during slurry-phase Fischer-Tropsch. Quarterly technical progress report No. 5, October 1, 1991--December 31, 1991

Description: The objective of this project is to investigate three possible routes to the formation of ethers, in particular methyl tert-butyl ether (MTBE), during slurry phase Fischer-Tropsch reaction. The three reaction schemes to be investigated are: Addition of isobutylene during the formation of methanol and/or higher alcohols directly from CO and H{sub 2} during slurry-phase Fischer-Tropsch. Addition of isobutylene to FT liquid products including alcohols in a slurry-phase reactor containing an MTBE o… more

Reservoir characterization by crosshole seismic imaging. Semi-annual progress report, 15 September 1991--14 September 1992

Description: This report covers the investigation on the field use of crosshole measurements in reservoir characterization. This investigation was planned for a four year effort. (Year 1) Preparation. (Year 2) Use of vertically polarized shear waves. (Year 3) Addition of horizontally polarized shear waves. (Year 4) Present static image of reservoir properties and observe the time varying phenomena in reservoir by reshooting high frequency compressional (P) survey. This report covers the first six months of … more

Thermal effects on the frequency response of piezoelectric crystals

Description: In this paper we describe a solution strategy to determine the natural frequencies of piezoelectric crystals subject to moderate changes in temperature and a variety of boundary constraints. The finite element equations governing piezoelectricity are derived based upon a Galerkin formulation of the problem. Suitable assumptions are made to linearize the steady-state (static) problem leading to an iteration scheme that can be used to refine the solution and include non-linear geometric effects c… more

End design of the SSC 58 mm High Gradient Quadrupole

Description: The end'' design of the High Gradient Quad. was done with consideration to the integrated field harmonics, the iron contribution, and the maximum field at the conductor. Magnetic analysis was done on the return end only, however the physical dimension of the lead end were determined as well. Using the cross-section of the windings and Cook's program BEND, we generated the physical end windings around the return end. Placing a single wire at the center of each turn the integrated gradient was co… more
