Flash hydropyrolysis of coal. Quarterly report No. 9, April 1-June 30, 1979

Description: Both the North Dakota lignite and New Mexico sub-bituminous coal have been hydrogasified in the Flash Hydropyrolysis unit with yields ranging up to about 85 to 90% conversion of the available carbon at 2500 psi and 875 to 900/sup 0/C. The lignite appears to be less reactive at lower pressure than the sub-bituminous coal, producing an average of 40% gaseous yield at 1000 psi and 900/sup 0/C while the sub-bituminous produced over 50%. The reactivity of both coals is dependent on the hydrogen part… more

Ceramic coatings on diesel engine components. Period covered: January 1979-August 1979

Description: Diesel engines with imporved thermal efficiency and fuel economy or flexibility will be required to meet automotive energy conservation goals. These goals can be met by minimizing engine heat loss to the coolant, i.e., by the use of a thermal insulating barrier on the interior surfaces of the combustion space. The development and testing of ceramic coatings for diesel engine components are discussed. These coatings include oxides of Al, Cr, Zr, Mg, Si, Ti, and Ca, and Mo and Ch carbides. Data o… more

Photoelectronic properties of zinc phosphide crystals, films and heterojunctions. Quarterly progress report No. 2, July 1-September 30, 1979

Description: The closed tube horizontal growth method has been pursued for the growth of single crystals of Zn/sub 3/P/sub 2/. The rate of material transport was increased by increasing the temperature difference between source and growth regions and by decreasing the distance involved. A boule with only 2 grains in a 12 mm diameter has been obtained. The as-grown resistivity of this single crystal Zn/sub 3/P/sub 2/ was 50 ohm-cm, which was reduced to 10 ohm-cm by subsequent annealing in hydrogen at 410/sup… more

Energy sensitivity and variability analysis of Populus hybrid short-rotation plantations in northeastern United States. Final report

Description: Production of biomass by corn-like plantations has been demonstrated by a number of researchers. These forest analogs of agronomic cropping systems have the potential to yield substantially more biomass per unit area than traditional forests. Care is needed in choosing the appropriate sites, species, spacing, and harvesting strategies. Opportunities for increased yields have been suggested for fertilization and irrigation. Utilization of the biomass from these dense plantations for energy was t… more
