Two dimensional NMR and NMR relaxation studies of coal structure

Description: This report covers the progress made on the title project for the project period. Four major areas of inquiry are being pursued. Advanced solid state NMR methods are being developed to assay the distribution of the various important functional groups that determine the reactivity of coals. Special attention is being paid to methods that are compatible with the very high magic angle sample spinning rates needed for operation at the high magnetic field strengths available today. Polarization inve… more

Innovative Clean Coal Technology (ICCT): 180 MW demonstration of advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from coal-fired boilers. Technical progress report, second quarter 1992

Description: This quarterly report discusses the technical progress of a US Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) Project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from a coal-fired boiler. The project is being conducted at Gulf Power Company`s Plant Lansing Smith Unit 2 located near Panama City, Florida. The primary objective of this demonstration is to determine the long-term effects of commerciall… more

Effects of catalytic mineral matter on CO/CO{sub 2} temperature and burning time for char combustion. Quarterly progress report No. 12, July--September 1992

Description: Results (solid-1600K, open-2000K surface temperature) from Fig.3 show that oxygen and nitrogen distributions are almost same although there is a little particle shrinkage (r{sub o}=0.009cm). C0{sub 2}/CO ratio drop significantly as the temperature increases, which is opposite to experimental results reported earlier. The cause of this behavior is mainly due to the lack of gas phase CO oxidation. Therefore, C0{sub 2}/CO ratio are directly related to C0{sub 2} and CO production of the heterogeneo… more

Transformations of Toluene Radical Cation in ZSM-5 and Silicalite

Description: Toluene radical cations produced by {gamma} irradiation at 77 K in ZSM-5 and Silicalite (isomorphous with ZSM-5 but nonpolar) undergo a reversible transformation to the norbornadiene radical cation at temperatures {le}150K. The transformation occurs to a greater extent in the more polar zeolite (ZSM-5). The substrate concentration plays an important role. Toluene radical cations undergo ion-molecule reactions to give benzyl radicals at low substrate loading at temperatures >200 K. At higher con… more
