METHOD OF PREPARING MICROSPHERIC HYDROCARBON OXYCHLORIDATION CATALYST Russian patent published in 1999 - IPC

Abstract RU 2139761 C1

FIELD: halogenation catalysts. SUBSTANCE: method consisting in preparing aluminum hydroxide and adding active component is distinguished by that the former is prepared by mixing aluminum oxychloride and sodium aluminate solutions at pH 8.5- 10.5 and temperature 20-60 C for 2 to 60 sec and stirring resulting suspension for 1 to 3 hr, followed by filtration, and washing precipitate to residual sodium oxide level below 1.5%. Active component is then brought in by mixing precipitate with cupric chloride and magnesium chloride followed by spray drying at dryer outlet gas temperature (130-200 C) and additional calcination of resulting microspheric catalyst at 600-660 C for 2 to 4 hr. EFFECT: simplified process and improved catalytic properties. 1 tbl
