2294a.     ---------------.  [MITTASCH, A.]  Early Studies of Multicomponent Catalysts.  Advances in Catalysis.  Academic Press, Inc., New York, 1950, vol. 2, pp. 81-104.

                      Historical development of multicomponent catalysts is given.  Their activity in NH3 synthesis, catalytic production of H2, hydrogenation of CO to CH4, hydrogenation of unsaturated organic compounds, production of organic compounds by catalytic reduction of CO with H2 under pressure, and catalytic oxidations is discussed.  52 refs. listed.
