Abstract
The disclosure relates to systems and methods that include using a plurality of reactors for the conversion of a stream of ammonia (NH3) to hydrogen (H2) and nitrogen (N2). The stream of ammonia is heated prior to introduction into each reactor. The reactors can be adiabatically operated.
Claims20
A system, comprising:
- an ammonia gas source;
- a plurality of reactor systems comprising first and second reactor systems, each reactor system comprising:
- a heater comprising an inlet and an outlet;
- a reactor comprising:
- a housing defining an internal space;
- a first inlet in fluid communication with the internal space of the housing and the outlet of the heater;
- a first outlet in fluid communication with the internal space of the housing;
- and
- an ammonia cracking catalyst disposed in the internal space of the housing;
- wherein:
- the ammonia gas source is configured to be in fluid communication with the inlet of the heater of the first reactor system;
- and
- the first outlet of the first reactor system is in fluid communication with the inlet of the heater of the second reactor system.

A method, comprising:
- heating a first ammonia stream;
- disposing the first ammonia stream in an interior region of a first reactor comprising a catalyst;
- converting at least a portion of ammonia in the first ammonia stream to hydrogen and nitrogen, thereby forming a second ammonia stream;
- removing the second ammonia stream from the interior region of the first reactor;
- heating the second ammonia stream;
- disposing the second ammonia stream in an interior region of a second reactor comprising a catalyst;
- and
- converting at least a portion of ammonia in the second ammonia stream to hydrogen and nitrogen.
