Abstract

Processo per la rimozione di impurezze gassose da una corrente di H2 contenente una prima classe di impurezze più facilmente asportabili, per esempio, e una seconda classe di impurezze più difficilmente asportabili, costituite principalmente da N2 e CH4 comprendente:A. il contatto a 5-50°C, con un letto di materiale particellare contenente Ni e/o composti di Ni, ove almeno l'1% in peso della quantità totale di Ni è presente in forma ridotta, fino a che dette impurezze più facilmente asportabili sono rimosse in modo essenzialmente completo;B. il contatto della corrente proveniente da A, a 400-600°C, con un letto di materiale getter non evaporabile.
