1,054,617. Catalysts. BADISCHE ANILIN- & SODA-FABRIK A. G. Nov. 4, 1965 [Nov. 5, 1964], No. 46726/65. Headings B1E and B1F. [Also in Divisions C2 and C5]. In a fluidised bed process for reacting gases or vapours in the presence of a finely divided catalyst, there are used hollow spheres the surface of which is perforated. The spheres may be of metallic or ceramic composition. The perforations are preferably circular and comparative sizes of sphere and perforation are gizen. Examples describe the use of hollow perforated stainless steel spheres in combination with catalysts containing (a) TiO 2 and V 2 O 5 , (b) reduced ZuO (c) 15% Cu on silicic acid (d) Ni Cu and Mu on silicic acid (e) Pt and K 2 CO 3 on carbon and (f) TiO 2 , Fe 2 O 3 and MoO 3 . Particle sizes, surface area and calcination temperatures are given. |
