Adapting domestic commercial catalysts for use in such important technological processes as the environmentally friendly production of hydrogen accompanied by СОх and NОх emissions is in demand under import substitution conditions. Ammonia seems to be the most promising Н2 accumulator, due to its high hydrogen density and simple storage and transportation. This work considers the possibility of using the domestic NIAP-03-01, NIAP-07-01, NIAP-06-06 catalysts and Со-Al2O3/SiO2 developed by the authors in the ammonia dissociation reaction. The conversion and hydrogen production capacity grow in the order NIAP-06-06<NIAP-03-01<NIAP-07-01<Со-Al2O3/SiO2. The conversion of ammonia on Со-Al2O3/SiO2 is close to 100% at 550°C and a gas hourly space velocity (GHSV) of 3000 h−1. The effective activation energies of all the catalysts are comparable to the available literature data for the ammonia decomposition reaction to potentially enable their application at moderate temperatures.
