D0 Silicon Upgrade: Calorimeter Installation Bridge Non-Destructive Test Result

Description: After the central calorimeter was installed on the center beam a cracked weld was found on the bridge. The weld was a partial penetration between the top rail plate and the T-1 steel nose section. The crack is fully across the width of the rail plate and the rail is depressed in a concave shape. That is, the depression is deeper in the center and feathers out to zero at the end of the rail. Upon close inspection it was obvious that there was no penetration of weld metal into the T-1 material. T… more

Deactivation by Carbon of Iron Catalysts for Indirect Liquefaction

Description: This report describes recent progress in a fundamental, three-year investigation of carbon formation and its effects on the activity and selectivity of promoted iron catalysts for synthesis, the objectives of which are: determine rates and mechanisms of carbon deactivation of unsupported Fe and Fe/K catalysts during CO hydrogenation over a range of CO concentrations, CO:H{sub 2} ratios, and temperatures; model the rates of deactivation of the same catalysts in fixed-bed reactors. During the fou… more

Monthly energy review, July 1990

Description: US total energy consumption in July 1990 was 6.7 quadrillion Btu Petroleum products accounted for 42 percent of the energy consumed in July 1990, while coal accounted for 26 percent and natural gas accounted for 19 percent. Residential and commercial sector consumption was 2.3 quadrillion Btu in July 1990, up 2 percent from the July 1989 level. The sector accounted for 35 percent of July 1990 total consumption, about the same share as in July 1989. Industrial sector consumption was 2.4 quadrill… more
