New Mexico's energy resources '81. Annual report of Bureau of Geology in the Mining and Minerals Division of New Mexico Energy and Minerals Department

Description: Although production of U/sub 3/O/sub 8/ declined only slightly in 1980, New Mexico's share of domestic production has declined from 48% in 1976 to 35% in 1980. Production projections indicate a continued decline in 1981 and lower production until at least 1984. New Mexico has 41% of total domestic reserves producible in the $50-per-lb cost category. In keeping with the anticipated steady depletion of reserves, production of crude oil in New Mexico was 69.9 million bls, a 6.3% decline in product… more

Clean, premium-quality chars: Demineralized and carbon enriched

Description: The goal of this project is to develop a bench-scale procedure to produce clean, desulfurized, premium-quality chars from the Illinois basin coals. This goal is achieved by utilizing the effective capabilty of smectites in combination with methane to manipulate the char yields. The major objectives are: to determine the optimum water- ground particle size for the maximum reduction of pyrite and minerals by the selective-bitumen agglomeration process; to evaluate the type of smectite and its int… more

Physical-chemical NO/sub x/ mechanisms in fluidized bed combustion

Description: Fluidized bed combustors operate in the large-particle (> 1 mm) high-velocity (> 1 m/s) fluidization regime which differs from most previous applications. These characteristics foster a distinctive volatiles evolution structure in the vicinity of the coal injectors of bottom-fed atmospheric fluidized beds (AFBC). The evolution of coal volatiles associated with bottom-fed AFBC was defined as the focal point. The major effort of the work was concerned with a group combustion model of dense … more

Comparative analysis of coal use options for reducing the dependence of utilities on imported oil

Description: The President and the Congress are finalizing National Goals to reduce the Nation's dependence on imported oil. A key element of these goals is the conversion of utilities from oil-fired to coal-fired to yield an import reduction of 0.75 MBD by 1990. Since these utilities already exist at fixed locations, this element of the National Goals has the focus of Appolo, Polaris, Minuteman and other major successful programs. It is indicated, therefore, that the program development and management tech… more

Hydrothermal Pretreatment of Coal. Quarterly Report No. 4, July 16--October 15, 1990

Description: During this period we studied the effects of 350{degrees}C treatment on Argonne-supplied Wyodak coal with n-alkane undecane in place of water in both 30 min. and 5 hr. experiments. Undecane was chosen because it has a critical temperature of 363{degrees}C (calculated), similar to that for water, and is present as a liquid phase at conditions. We anticipated results little different from those from the simple thermal treatment (coal under N{sub 2}) at the same conditions. In that case we had fou… more

Extraction of Potential Pollutants From Ohio Coal by Synergistic Use of Supercritical Fluids. Final Report

Description: A synergistic supercritical extraction process was developed and its feasibility demonstrated using a semi-batch extraction process unit. The process was found to be effective in selectively cleaning organic sulfur from Ohio coals. Optimal case involved a mixture of CO{sub 2}, H{sub 2}O, and CH{sub 3}OH, and the removal of organic sulfur ranged from 35 to 55%. Combined with pyrite and mineral matter removal by gravity, the resulting coals would have 20--30% increased heating values and SO{sub 2… more

Power plant siting; an application of the nominal group process technique

Description: The application of interactive group processes to the problem of facility siting is examined by this report. Much of the discussion is abstracted from experience gained in applying the Nominal Group Process Technique, an interactive group technique, to the identification and rating of factors important in siting nuclear power plants. Through this experience, interactive group process techniques are shown to facilitate the incorporation of the many diverse factors which play a role in siting. In… more
