THREE-DIMENSIONAL MESH GRID FOR CATALYTIC REACTIONS

摘要

FIELD: catalytic processes. SUBSTANCE: new three-dimensional precious- metal mesh grids for catalytic oxidation of ammonia and other gas- phase reactions are used. The highest yield of product with smooth proceeding of process and great service life of mesh grid is observed when catalyst mesh grid is bound in two or more layers and layers are joined to each other by means of nap threads. Of importance is possibility of introducing large number of nap threads per unit area and possibility of orienting them in parallel to direction of reaction gas stream. EFFECT: enhanced efficiency of catalytic process.
