3703.     WILLFROTH, -----, AND GIESEN, -----.  [Improvement of Consistency and Durability of Catalyst Used in Methanol Synthesis.]  Board of Trade, German Division, Technical Information and Documents Unit.  F. D. 1030/47, Jan. 5, 1928, 9 pp.; Fuel Abs., 1948, No. 2388.

        Experiments are described aiming at improving the consistency and durability of ZnO-base catalyst by adding Mg salts.  Shows process for the manufacture of various types of improved catalysts, as well as their effects in the catalytic hydrogenation of CO and of other C compounds.  Further research on ZnO-Mg-Cr catalysts is intimated.
