Methane oxidation over dual redox catalysts

Description: Review and analysis of the literature data on electron transfer itself and electron transfer oxidation of alkyl radicals was done in order to understand the mechanism by which methyl radical can be oxidized to CH{sub 3}{sup +} and further substituted by OH{sup {minus}} to form methanol. This allowed to compare and classify the various possible reaction patterns, understand the mechanism and circumstances of operation of each of them and select those which can be involved in oxidation of methyl … more

LIMB Demonstration Project Extension

Description: The basic goal of the Limestone Injection Multistage Burner (LIMB) demonstration is to extend LIMB technology development to a full- scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO{sub x} and NO{sub x} emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintain… more

L-star pulsed coal combustor for residential space heating

Description: This quarter, substantial improvement in the coal carbon conversion was achieved. Specifically, for a scaled-down version of the residential combustor, coal carbon conversions exceeding 97 percent were realized, when utilizing methane as carrier gas for the coal. Design changes include insulation of the combustor, introduction of a flame holder, combustion air preheat and presence of an obstructing plate at the combustor exhaust port. Only the first two changes contributed towards substantial i… more

Finding the magnetic center of a quadrupole to high resolution: A draft proposal

Description: In a companion proposal it is proposed to align quadrupoles of a transport line to within transverse tolerances of 5 to 10 micrometers. Such a proposal is meaningful only if the effective magnetic center of such lenses can in fact be repeatably located with respect to some external mechanical tooling to comparable accuracy. It is the purpose of this note to describe some new methods and procedures that will accomplish this aim. It will be shown that these methods are capable of yielding greater… more

Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

Description: AMAX Research Development Center (AMAX R D) has been investigating methods for enhancing the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For the present program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-… more

Secondary atomization of single coal-water fuel droplets

Description: The evaporative behavior of single, well characterized droplets of a lignite coal-water slurry fuel (CWSF) and a carbon black in water slurry was studied as a function of heating rate and droplet composition. Induced droplet heating rates were varied from 0 to 10{sup 5} K/s. Droplets studied were between 97 and 170 {mu}m in diameter, with compositions ranging from 25 to 60% solids by weight. The effect of a commercially available surfactant additive package on droplet evaporation rate, explosiv… more

Precision measurements of the SLC reference magnets

Description: Two spectrometers, one on each extraction line of the SLC, have been installed to momentum analyse each SLC beam pulse and determine the electron and positron beam energies. A method of determining and monitoring the absolute magnetic field strength for these dipoles has been developed. A total error on the magnetic field integral of {delta}{integral}Bdl/{integral}Bdl = 1 {times} 10{sup {minus}4} has been achieved. The field integral can be monitored continuously during SLC beam operation using… more

Vibration analysis of APS magnet/support systems based on the finite element method

Description: Prediction of the dynamic response of APS magnet/support systems requires knowledge of the free vibrational characteristics, including natural frequencies, modes, and modal damping ratios. A preliminary dynamic analysis of the magnet/support system of a typical section of the APS storage ring, as presented in the APS Conceptual Design Report, was performed to gain insight. The preliminary analysis is based on the assumption that the support girder could be considered rigid relative to the stiff… more

Minimal Technologies Application Project: Planning and installation

Description: Intensive and continuous tactical training during the last 35 years at the Hohenfels Training Area in West Germany has caused the loss of vegetative ground cover and has accelerated soil erosion rates, resulting in extensive environmental damage, safety hazards, and unrealistic training habitats. The objectives of this project are to develop and evaluate revegetation procedures for establishing adequate vegetative cover to control erosion at minimal costs and disruption to training activities. … more

Calculation of integrated luminosity for beams stored in the Tevatron collider

Description: A model for calculating the integrated luminosity of beams stored in the Tevatron collider will be presented. The model determines the instantaneous luminosity by calculating the overlap integral of bunched beams passing through the interaction region. The calculation accounts for the variation in beam size due to the beta functions and also for effects due to finite longitudinal emittance and non-zero dispersion in the interaction region. The integrated luminosity is calculated for the beams a… more

Mass transport in salt repositories: Steady-state transport through interbeds

Description: Salt has long been a candidate for geologic disposal of nuclear waste. Because salt is extremely soluble in water, the existence of rock salt in the ground atest to the long-term stability of the salt. Both bedded salt and salt domes have been considered for nuclear waste disposal in the United States and Europe. While the salt is known to be quite pure in salt domes, bedded salt is interlaced with beds of sediments. Traditionally rock salt has not been considered water-conducting, but sediment… more
