High pressure and low temperature recycled nh3 reforming process

Abstract

The present invention relates to a process for NHI; reforming, the process comprising (i) feeding a feed stream comprising NH3 into a reactor unit, wherein the reactor unit has a reactor unit inlet and a reactor unit outlet, wherein the reactor unit comprises a catalytic material: (ii) contacting the feed stream with the catalytic material in the reactor unit, for obtaining a product stream comprising H2, N2, NH3, and optionally H2O, wherein contacting is performed at a pressure in the range of from 1 to 100 bar(abs) and at a temperature in the range of from 50 to 750° C.; (iii) optionally separating H2O in the product stream obtained in (ii) for obtaining a dehydrated product stream comprising H2, N2, and NH3; (iv) separating NH3 from the product stream obtained in (ii) or from the dehydrated product stream obtained in (iii) for obtaining a purified product stream comprising N2 and H2: (v) recycling the separated NH3 obtained in (iv) to (i).
