The catalysts (previously produced as KDA-10A and KDA-18A) are used for catalytic ammonia dissociation at pressures up to 3.0 MPa, in the temperature range 600 – 950 °C and space velocity in the range 500 - 5000 h-1 to produce pure mixture of nitrogen and hydrogen employed as protective (controlled) atmosphere and reducing gas in industry.

Catalyst should be reduced before exploiting using any hydrogen-containing gas or gaseous ammonia.
