D-50 in Situ Characterization of High-Temperature Shift Catalysts

Autor: Kenny Ståhl, R. E. Johnsen, A. M. Molenbroek

Publikováno v: Powder Diffraction. 22:190-190

High-temperature shift catalysts are used in chemical industry to catalyze the watergas shift reaction in which CO with steam is converted to CO2 and H2. This reaction is an intermediate process in the industrial production of hydrogen used for e.g.

Ultrasonic Extraction of Insecticides in Soil. I. Comparison of Extraction Methods and Solvent Systems Over Three Time Intervals1

Autor: R. I. Starr, R. E. Johnsen

Publikováno v: Journal of Economic Entomology. 60:1679-1682

The ultrasonic extraction of heptachlor epoxide and dieldrin from a sandy loam soil 1 day, 1 month, and 2 months after treatment was studied using 6 solvent systems and was compared with blender and roller-extraction methods. The solvents used were b
