METHOD OF PRODUCTION OF CATALYTIC ELEMENT Russian patent published in 2005 - IPC

Abstract RU 2259879 C2

FIELD: production of catalytic elements for decontamination of gas emissions.

SUBSTANCE: proposed method includes forming catalytically active layer on metal carrier by plasma spraying of powder composition at linear velocity of 100-150 m/min, forming cellular structure in form of longitudinal passages due to corrugation of metal carrier with catalytically active layer applied to it. The catalytically inactive powder composition is used as initial material for plasma spraying at the following ratio of components, mass-%: aluminum, 3.5; chromium oxide, 2-5; tungsten oxide, 0.8-1.2; cerium, lanthanum and neodymium oxides, 1.8-2.2 in sum; the remainder being aluminum hydroxide.

EFFECT: enhanced strength of adhesion with substrate at high mechanical strength and catalytic activity.
