G.] [Making Solid Shaped Catalysts From Finely-Ground Material.] German Patent Appl. I 70,640. OZ 13043, filed Oct. 15, 1941 (Cl. 12 g). FIAT Reel 172, frame 255; PB 25,616; TOM Reel 20, item 161, frames 2,583-2.587. Part of the (10-20%) is ground to a colloidal fineness and mixed in moist condition with the less finely ground material (80% passing through a sieve with 10,000-mesh per cm.2). and the mixture formed and heated. Such catalysts find use in the conversion of carbonaceous materials, as in the refining and aromatizing pressure hydrogenation of coal and the like, and in the synthesis of hydrocarbons from CO and H2. |
