Abstract

The present invention relates to an adiabatic, zoned reactor for the reforming of NH3 to N2 and H2, the reactor particularly comprising n reaction zones arranged in sequence and extending along the axial length L of the reactor, wherein n is an integer in the range of from 2 to 5, wherein independently from one another, each of the n reaction zones comprises one or more catalytic components, wherein from the inlet reaction zone to the outlet reaction zone each reaction zone displays a lower light-off temperature T50 in the reforming of NH3 to N2 and H2 then the subsequent downstream one. Further, the present invention relates to a production unit comprising said reactor, a process for the reforming of NH3 to N2 and H2, and use of said reactor and said production unit.
