A catalyst for the decomposition of NO under the conditions of the Ostwald process, comprising a carrier and a coating made of rhodium, rhodium/palladium or rhodium oxide applied thereto, ensures to yield NO with a particularly low content of laughing gas as the first process product.

[object Object]

A process and a device for reducing the nitrous oxide which is formed during the catalytic combustion of ammonia and oxygen to form nitrogen oxides. A catalyst system including at least one first catalyst mesh element and at least one second catalyst mesh element is used for the catalytic combustion of ammonia and oxygen to form nitrogen oxides, where the minimum of one first catalyst mesh element is a platinum-rhodium mesh and the minimum of one second, downstream catalyst mesh element is a palladium-rhodium mesh with 2-4 wt. % of rhodium.

Method and apparatus for reducing nitrous oxide

The use of ceramic meshes is offered for spacing catalyst meshes apart from one another in the production of HCN, especially by the Andrussov process.
