METHOD OF OBTAINING CeO-SnO- BASED CATALYST ON FIBREGLASS CARRIER Russian patent published in 2015 - IPC B01J37/08 B01J37/02 B01J23/10 B01J23/14 

FIELD: chemistry.

SUBSTANCE: method includes preparation of carrier by thermal processing at 500°C, application of alcohol film-generating solution by method of stretching at rate 100 mm/min, drying at 60°C for 1 h and annealing at 750°C for 4 h. Film-generating solution is applied on fibreglass carrier by method of soaking with further drying at 60°C for 1 h and annealing at 600-750°C for 1 h. Catalyst, which is obtained in form of cloth, is cut at output in accordance with reactor shape and packed in layers at angle of 20-30°, with formation of honeycomb structure, with the following component ratio in film-generating solution, wt %: Ce(NO₃)₃·6H₂O - from 6.0 to 12.0, SnCl₄·5H₂O - from 16.6 to 22.3, C₆H₄OHCOOH - from 9.1 to 10.0, 96%-by weight C₂H₅OH - the remaining part.

EFFECT: method makes it possible to obtain catalysts, characterised by high permeability of gas mixture flow.
