Abstmet A new method of additions is described for x-ray diffraction determination of trace crystalline silica. The method is derived from Klug and Alexander, X-ray Diffraction Procedures (Wiley, 1974, p. 536, Bqn. 7-14) and is expressed as x = sR,(l -R,)/(R, -Rx) where x and s are the concentration
The dehydrogenation of isobutane on a commercial chromia-alumina catalyst was studied using a conventional and a membrane reactor. A series of differential runs were conducted varying the temperature and feed composition. Extensive loss of catalyst activity was observed within the first two or three
