Effects of catalytic mineral matter on CO/CO sub 2 , temperature and burning time for char combustion

Description: The temperature of a char particle burning in an oxygen containing atmosphere is the product of a strongly coupled balance between particle size and physical properties, heat transfer from the particle, surface reactivity, CO/CO{sub 2} ratio and gas phase diffusion in the surrounding boundary layer and within the particle. CO{sub 2}/CO ratios can be strongly influenced by catalytic material in the carbon and by the char temperature. In this program we are measuring the CO{sub 2}/CO ratio for bo… more

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts

Description: During this period, we focused our attention in analyzing the magnetic nature of the extensively used trimetallic catalyst system Cu-Co-Cr for the production of higher alcohols. We believe that there could be some correspondence between the catalytic and magnetic behaviors of the transition metal catalyst systems. Both the morphology and metallic charge distribution of the particles are known to govern the catalytic as well as the magnetic properties of the system.

The inverse problem'' to the evaluation of magnetic fields

Description: In the design of superconducting magnet elements, such as may be required to guide and focus ions in a particle accelerator, one frequently premises some particular current distribution and then proceeds to compute the consequent magnetic field through use of the laws of Biot and Savart or of Ampere. When working in this manner one of course may need to revise frequently the postulated current distribution before arriving at a resulting magnetic field of acceptable field quality. It therefore i… more

Nitric acid requirement for treating sludge

Description: The hydroxylamine nitrate (HAN) precipitate hydrolysis process produces sufficient oxidant (nitrate) such that the resulting blend of formic acid treated sludge and the aqueous product from hydrolysis (PHA) produces a melter feed of acceptable redox (i.e. Fe+2/Total Fe <0.33). With implementation of Late Washing (to reduce the nitrite content of the tetraphenyborate slurry produced during In-Tank Precipitation to 0.01M or less), HAN is no longer required during hydrolysis. As a result, the nitr… more

HLNC calibration and application to waste measurement

Description: This paper addresses problems of calibration and estimation of a parameter, p{sub o}, in high level neutron coincidence counting (HLNC) measurement. The presentation begins with a deductive approach, based on the generally accepted physical equations which are satisfied by the total and coincidence count rates. A new approach for the estimation of p{sub o} via measurement and a new calibration procedure consistent with the physical theory of coincidence counting measurement are presented. The a… more

Clean gasoline reforming with superacid catalysts. Quarterly progress report, April--June 1992

Description: It has been observed for a number of the Zr catalysts that the maximum MCH conversion (ca. 20 wt.%) can be obtained in 15 min. using a reaction temperature of 150{degrees}C and 1 atm. of H{sub 2}, and no further reaction occurs during 120 minutes. Typical results for these catalysts as well as catalyst which show lower activities using the 15 min. residence time are shown in Figure 2. Both catalyst formulations, a Pt/ZrO{sub 2}/SO{sub 4} and a Fe/Mn/ZrO{sub 2}/SO{sub 4} show this behavior. The … more

EC Vacuum Vessel Finite Element Analysis

Description: This Note contains a summary of the results of the finite element analysis of the EC Cryostat vacuum vessel performed by Dave Rudland in 1987. The results are used in the structural evaluation of the EC cryostats presented in Engineering Note 194. It should also be noted that the adequacy of the design of the vacuum vessels was reviewed and verified by the Battelle Memorial Institute. Battelle used a shell of revolution program to essentially duplicate the FEA analysis with similar results. It … more

Fuzzy set classifier for waste classification tracking

Description: We have developed an expert system based on fuzzy logic theory to fuse the data from multiple sensors and make classification decisions for objects in a waste reprocessing stream. Fuzzy set theory has been applied in decision and control applications with some success, particularly by the Japanese. We have found that the fuzzy logic system is rather easy to design and train, a feature that can cut development costs considerably. With proper training, the classification accuracy is quite high.
