CATALYTIC ELEMENT OF REGULAR CELLULAR STRUCTURE FOR HETEROGENEOUS HIGH- TEMPERATURE REACTIONS

摘要

FIELD: high-temperature reaction catalysts. SUBSTANCE: catalytic element of regular cellular structure for heterogeneous high- temperature reactions, for example conversion of ammonia, which is made as a layer from separate prisms connected by lateral sides and having cellular channels. Separate prisms on stacking them in a cellular structure layer have a gap between lateral sides equal to 0,1-1,0 diameter of the cellular channel. For laying the layer peripherally, the triangular and trapezoid blocks are used truncated at a level corresponding to diameter of the contact apparatus. Second-step ammonia oxidation catalyst is composed of, % mas.: Fe₂O₃- 80-90, Cr₂O₃- 5-10, and Al₂O₃- 5-10. EFFECT:: increased strength and service time. 3 cl, 7 ex
