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

Fundamental mechanisms in flue gas conditioning

Description: This project is divided into four tasks. The Management Plan was developed in task 1. Task 2, Evaluation of Mechanisms in FGD Sorbent and Ash Interactions, focuses on the characteristics of binary mixtures of these distinct powders. Task 3, Evaluation of Mechanisms in Conditioning Agents and Ash, is designed to examine the effects of various conditioning agents on fine ash particles to determine the mechanisms by which these agents alter the physical properties of the ash. Tasks 2 and 3 began w… more

Development of advanced NO sub x control concepts for coal-fired utility boilers

Description: CombiNO{sub x} is an integration of three technologies: modified reburning, promoted selective noncatalytic reduction (SNCR) and methanol injection. These technologies are combined to achieve high levels of NO{sub x}, emission reduction from coal fired power plants equipped with SO{sub 2} scrubbers. The first two steps, modified reburning and promoted SNCR are linked. It has been shown that, performance of the SNCR agent is dependent upon local oxidation of CO. Reburning is used to generate the… more

Analysis of K-Area core samples for K-Area formation stabilization work

Description: Foundation stabilization work in K-Area has been recently completed by Bechtel Inc. This effort involved pumping cement and cement-sand grout into unconsolidated sediments under K-Area. Subsequent to stabilization, core samples were collected to document the extent of grout flow in the area. Samples of this core were examined by SRTC personnel in support of the grouting program at the request of Bechtel personnel. This report summarizes the results of the SRTC study.

Catalyst and process development for synthesis gas conversion to isobutylene. Quarterly report, April 1, 1992--June 30, 1992

Description: A rate equation for carbon monoxide consumption showing first order in CO and 0.5 order in hydrogen indicates the rate controlling step involves dissociated hydrogen. The inhibition of the rate with carbon dioxide is also shown. Examination of the hydrocarbon distributions indicates a see-saw effect with the C{sub 4}s representing the fulcrum and methane and C{sub 5}{sup +} the end points. The shift in the distributions tends to be towards the C{sub 5}{sup +} for high pressures and long residen… more

Low severity coal liquefaction promoted by cyclic olefins. Quarterly report, April--June 1992

Description: Low severity coal liquefaction allows for solubilization of coal with reduced gas make. These lower severity conditions may result in some selective bond rupture. Promotion of coal solubilization through hydrogen transfer using highly active and effective hydrogen donors is the objective of this study. The highly effective donors being tested are cyclic olefins. Representative cyclic olefins are isotetralin, which is 1,4,5,8-tetrahydronaphthalene, and 1,4,5,8,9,10-hexahydroanthracene. These com… more

D0 Collision Hall Outdoor Fresh Air Makeup

Description: This note will briefly describe the collision hall ventilation system and how D0 will monitor outside air makeup and what actions occur in the event of system failures. The Dzero collision hall has two different fresh air makeup conditions it must meet. They are: (1) Tunnel Barriers removed-Fresh air makeup = 4500 CFM; and (2) Tunnel Barriers in place-Fresh air makeup = 2800 CFM. This note demonstrates how the fresh air minimums are met and guaranteed. The air flow paths and ducts at D0 for bot… more

Confined zone dispersion flue gas desulfurization demonstration

Description: The confined zone dispersion (CZD) process involves flue gas post-treatment, physically located between a boiler's outlet and its particulate collector, which in the majority of cases is an electrostatic precipitator. The features that distinguish this process from other similar injection processes are: Injection of an alkaline slurry directly into the duct, instead of injection of dry solids into the duct ahead of a fabric filter. Use of an ultrafine calcium/magnesium hydroxide, type S pressur… more
