Low severity coal liquefaction promoted by cyclic olefins. Quarterly report, April--June 1992
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 compounds are hydroaromatics without aromatic rings and have been shown to be highly effective donors. The objective of the work performed in this study during this quarter was to evaluate reaction parameters for low severity liquefaction reactions using the cyclic olefin, hexahydroanthracene, and the aromatic, anthracene. These model compounds were reacted under a variety of conditions to evaluate their reactivity without coal. The reactions were performed under both thermal and catalytic conditions. Finely divided catalysts from different molybdenum precursors were used to determine their activity in promoting hydrogenation and hydrogen transfer at low severity conditions. The catalysts used were Molyvan L, sulfurized oxymolybdenum dithiocarbamate, molybdenum naphthenate, and Molyvan 822, organo molybdenum dithiocarbamate.

Flue gas conditioning for improved particle collection in electrostatic precipitators. Quarterly technical report
The purpose of this research program is to identify and evaluate a variety of additives capable of increasing particle cohesion which could be used for improving collection efficiency in an ESP. A three-phase screening process will be used to provide the, evaluation of many additives in a logical and cost-effective manner. The three step approach involves the following experimental setups: 1. Provide a preliminary screening in the laboratory by measuring the effects of various conditioning agents on reentrainment of flyash particles in an electric field operating at simulated flue gas conditions. 2. Evaluate the successful additives using a 100 acfm bench-scale ESP operating on actual flue gas. 3. Obtain the data required for scaling up the technology by testing the two or three most promising conditioning agents at the pilot scale.

D0 Collision Hall Outdoor Fresh Air Makeup
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 both AHU1 and EF-7 are fixed. The blower throughputs are not variable. The software stops on AHU1's dampers will be set for a minimum of 2800 cfm or 4500 cfm of outdoor air continuously added to the HVAC flow stream depending on the tunnel barrier state. AHU1 and EF-7 both have monitoring that can determine reliably as to whether the respective blower is on or off. Since the outside air makeup is fixed as long as the blowers are running, and the software AHU1 damper limits are set, we can rely on the blower status indicators to determine as to whether the collision hall is receiving the proper amount of outside makeup air.

Confined zone dispersion flue gas desulfurization demonstration
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 pressure-hydrated dolomitic lime. This commercial product is made from plentiful, naturally occurring dolomite. Low residence time, made possible by the high effective surface area of the Type S lime. Localized dispersion of the reagent. Slurry droplets contact only part of the gas while the droplets are drying, to remove up to 50 percent of the S0{sub 2} and significant amounts of NO{sub x}. The process uses dual fluid rather than rotary atomizers. Improved electrostatic precipitator performance via gas conditioning from the increased water vapor content, and lower temperatures. Supplemental conditioning with S0{sub 3} is not believed necessary for satisfactory removal of particulate matter.

Two dimensional NMR and NMR relaxation studies of coal structure. Progress report, September 13, 1991--December 31, 1991
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 inversion methods utilizing the difference in heat capacities of small groups of spins are particularly promising. Methods combining proton-proton spin diffusion with {sup 13}C CPMAS readout are being developed to determine the connectivity of functional groups in coals in a high sensitivity relay type of experiment. Additional work is aimed a delineating the role of methyl group rotation in the proton NMR relaxation behavior of coals.

Fundamental mechanisms in flue gas conditioning. Quarterly report, January 1992--March 1992
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 with an extensive literature search and the assembly of existing theories. This phase of the project is now complete. During the past quarter, initial preparations of laboratory equipment for laboratory testing have been made. A plan for initial laboratory tests has been submitted to the Project Manager for review. Laboratory testing will commence once these laboratory plans have been formally approved. The results of the work performed under task 2 and 3 will be included in a Flue Gas Conditioning Model that will be issued under task 4. The Final Report for the project will also be prepared under task 4.

Development of advanced NO{sub x} control concepts for coal-fired utility boilers. Quarterly technical progress report No. 5, October 1--December 31, 1991
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 optimum amount of CO to promote the SNCR agent, although lower levels of reburning are needed than are traditionally applied in the reburning process. If the reburn fuel is natural gas, the combination of reburning and SNCR may result in a significant cost savings over conventional reburning. The third step, injection of methanol into the flue gas, is used to convert NO to NO{sub 2} which may subsequently be removed in a wet scrubber.

Quantification of tritium ``heels`` and isotope exchange mechanisms in La-Ni-Al tritides
Formation of tritium heels in LANA (LaNi{sub 5-x}Al{sub x}) 0.30 (x=0.30) and 0.75 tritides was quantified; size of the heel is dependent on storage and processing conditions. Absorption-desorption cycling of the tritide beds mitigates formation of the tritium heel and can reduce its size. The higher pressure material LANA 0.30 showed slower heel formation than LANA 0.75; this allows more tritium to be removed at the maximum processing temperature. In plant application, LANA 0.30 beds are used as compressors; except during compressor operation, their aging will be very slow. Tritium heel removal by D exchange was demonstrated. Absorption-desorption cycling during an exchange cycle does not improve the exchange efficiency. Residual tritium can be removed to very low levels. For a tritide bed scheduled for removal from the process, a final tritium level can be estimated based on the number of D exchange cycles. 13 refs, 8 figs, 6 tabs.
