Removal of H/sub 2/S from geothermal steam. Semi-annual report, April 1-October 31, 1975

Description: The program objective is to identify and evaluate a technique to remove hydrogen sulfide from geothermal steam before it is used for power generation. The last six months were spent in the literature search, sorbent preparation and evaluation, and construction of an experimental apparatus. Zn0, mentioned in the original proposal as a good candidate for H/sub 2/S adsorption, was verified as such by the literature search and laboratory experiments. However, regeneration of sulfided sorbent proved… more

Baseline Gas Turbine Development Program Twelfth Quarterly Progress Report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. The endurance engine was modified to incorporate a power turbine drive to the regenerators in order to simulate free rotor (upgraded) conditio… more

Nuclear Chemistry Research. Progress Report, November 1, 1974--October 31, 1975

Description: The major effort in the high-energy nuclear chemistry program was the study of cross sections and kinematic properties of products formed from the interaction of 1- to 300-GeV protons with heavy- (Bi and U) and medium-mass (Cu, Ag) nuclei. The products studied ranged in mass from approximately 20 to that of the target nucleus. Except in the case of near-target product nuclei ($delta$A approximately 10 to 20), no substantial change in cross section or recoil properties was observed at 300 GeV fr… more
