METHOD FOR OBTAINING MICROSPHERICAL CATALYST OF OXIDATIVE ETHYLENE CHLORINATION Russian patent published in 2017 - IPC B01J37/02 B01J37/08 B01J27/122 B01J27/138 B01J35/08 

FIELD: chemistry.

SUBSTANCE: method consists of the stages for obtaining micro-spherical aluminium oxide carrier through spraying the suspension, which includes the 55-90 wt % of aluminium monohydrated of the pseudo-boehmitic structure, 35-5 wt % of aluminium hydroxychlorid and 10-5 wt % of modified starch in the flue gas environment, by the calcination of the carrier, impregnation of the received carrier of the water absorption by the solutions of salts of copper chlorides and chlorides of alkali and alkaline earth elements, by the calcination of the catalyst.

EFFECT: production of a microspherical catalyst for the oxidative chlorination of ethylene with a high catalytic activity and a resistance to abrasion in a fluidized mode.
