Downhole Steam Injector. [Patent Application]

Description: An improved downhole steam injector has an angled water orifice to swirl the water through the device for improved heat transfer before it is converted to steam. The injector also has a sloped diameter reduction in the steam chamber to throw water that collects along the side of the chamber during slant drilling into the flame for conversion to steam. In addition, the output of the flame chamber is beveled to reduce hot spots and increase efficiency, and the fuel-oxidant inputs are arranged to … more

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

Renewable Energy and Environmental Sustainability Using Biomass From Dairy and Beef Animal Production: Final Report, Volume 1

Description: The Texas Panhandle is regarded as the 'Cattle Feeding Capital of the World', producing 42% of the fed beef cattle in the United States within a 200-mile radius of Amarillo generating more than 5 million tons of feedlot manure/year. Apart from feedlots, the Bosque River Region in Erath County, just north of Waco, Texas with about 110,000 dairy cattle in over 250 dairies, produces 1.8 million tons of manure biomass (excreted plus bedding) per year. While the feedlot manure has been used extensiv… more

Clean Energy Technologies: A Preliminary Inventory of the Potential for Electricity Generation

Description: The nation's power system is facing a diverse and broad set of challenges. These range from restructuring and increased competitiveness in power production to the need for additional production and distribution capacity to meet demand growth, and demands for increased quality and reliability of power and power supply. In addition, there are growing concerns about emissions from fossil fuel powered generation units and generators are seeking methods to reduce the CO{sub 2} emission intensity of … more

Advanced Biocatalytic Processing of Heterogeneous Lignocellulosic Feedstocks to a Platform Chemical Intermediate (Lactic acid Ester)

Description: The development of commercial boi-based processes and products derived from agricultural waste biomass has the potential for significant impact on the economy and security of our nation. Adding value, rather than disposing of the waste of agriculture, can solve an environmental problem and reduce our dependence on foreign sources of fossil fuel for production of chemicals, materials and fuels.

Hydrothermal pretreatment of coal. [Heating dry; in liquid center of 150--350 degrees C, and in undecane]

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

Efficient ultrasonic grinding: a new technology for micron-sized coal. Quarterly technical progress report No. 2, December 16, 1979-March 15, 1980

Description: Work focused on establishing experimentally determined parameters for ultrasonic comminution and their translation into the design of an ultrasonic comminution array for Phase I testing. Early work indicated that continuous removal of fines during communition could significantly increase the production of -10 micron particles. Similarly, varying the mechanical gain of the ultrasonic comminution apparatus and thereby increasing the strain amplitude of the system was shown to enhance fines produc… more
