Abstract
Przedmiotem wynalazku jest sposób katalitycznej konwersji amoniaku do wodoru i azotu polegający na tym, że strumień gazu w postaci amoniaku, przy obciążeniu 0,5 - 6,5 kg/h•kg<sub>kat</sub>, przepuszcza się przez umieszczony w reaktorze katalizator stanowiący niklowy nośnik katalityczny z naniesioną na nim fazą aktywną w postaci nanocząstek metali przejściowych Pd oraz Re, o rozmiarach nanocząstek od 1 do 100 nm, przy czym zawartość nanocząstek fazy aktywnej na powierzchni nośnika katalitycznego wynosi od 0,01% wag. do 6% wag., a stosunek molowy nanocząstek Pd do Re wynosi od 1:20 do 20:1, a proces prowadzi się w temperaturze od 340°C do 580°C.
