Abstract
The invention relates to a precious metal mesh which is knitted on a flat-bed knitting machine, having at least two float stitches per wale, thus having a significantly higher density for a given latch needle density of the flat-bed knitting machine than the precious metal mesh according to the prior art.
Claims17
A method for the catalytic oxidation of ammonia, comprising the following steps of
- providing one or more precious metal meshes, wherein at least one of the provided one or more precious metal meshes is a knitted precious metal mesh that comprises n wires per row and at least two, at most (n−1) float stitches per wale, wherein:
- n>3;
- installing a mesh stack containing said knitted precious metal mesh in a flow reactors;
- supplying a gas containing ammonia and oxygen at a temperature in the flow reactor of between 500° C. and 1300° C. and a pressure of between 0.1 MPa and 1.4 MPa.
