Patent DE-4325690-A1 (DE)
Inventor: HUMS ERICH DR
IPC: B01J38/44
Filed: 1993-07-30
Abstract: A process is disclosed for recovering components of a catalyst (4, 6, 8), in particular a spent DeNox catalyst. The catalyst (4,6, 8) is ground and the ground catalyst is then shaped into bodies (18) having a defined grain. Alternatively, the ground catalyst (4, 6, 8) is applied on a reducing agent (36) with a defined grain and hardened thereon. The thus produced bodies (18) or the thus modified reducing agents (38), and if required an additional reducing agent (20, 36), are then chlorinated in reducing conditions. Titanium tetrachloride TiCl4 is then separated by distillation from the other chlorine and/or chlorine-oxygen compounds contained in the gas mixture produced during chlorination. The thus obtained titanium tetrachloride TiCl4 is burned with oxygen O2 or with oxygen O2 and hydrogen H2. The thus recovered titanium dioxide pigment meets the specification of commercially available titanium dioxide pigments and may thus be used for producing new DeNOx catalysts. This process and the arrangement (2, 32) are in principle suitable for reusing the most different types of metal oxide catalysts that contain titanium dioxide as base material.
