Abstract
The present disclosure provides systems and methods for processing ammonia. The system may comprise one or more reactor modules configured to generate hydrogen from a source material comprising ammonia. The hydrogen generated by the one or more reactor modules may be used to provide additional heating of the reactor modules (e.g., via combustion of the hydrogen), or may be provided to one or more fuel cells for the generation of electrical energy.
Claims30
An ammonia reforming system, comprising:
- one or more reactors comprising one or more catalysts therein, wherein the one or more reactors are configured to decompose ammonia (NH3) to generate a reformate stream comprising at least hydrogen (H2), nitrogen (N2), and unconverted ammonia, wherein the one or more reactors are in fluid communication with one or more storage tanks;
- a plurality of heating elements in thermal communication with the one or more catalysts, wherein the plurality of heating elements comprise at least one electrical heater and at least one combustion heater,
- wherein the at least one combustion heater is configured to combust at least a portion of the H2 in the reformate stream to heat the one or more reactors to a temperature within a target temperature range;
- a fuel cell configured to consume a first fraction of the H2 in the reformate stream from the one or more reactors to generate electricity;
- and
- an adsorbent configured to adsorb the unconverted ammonia,
- wherein the system is configured to desorb the unconverted ammonia from the adsorbent using an exhaust of the at least one combustion heater to regenerate the adsorbent.

An ammonia decomposition system, comprising:
- one or more reactors comprising one or more electrically-heated reactors comprising one or more catalysts, and one or more combustion-heated reactors comprising one or more catalysts;
- at least one electrical heater configured to heat the one or more electrically-heated reactors of the one or more reactors to a first target temperature range, wherein the at least one electrical heater is in thermal communication with the one or more catalysts of the one or more electrically-heated reactors;
- wherein the one or more electrically-heated reactors are configured to decompose ammonia (NH3) at the first target temperature range to generate a reformate stream comprising hydrogen (H2), nitrogen (N2), and unconverted ammonia;
- at least one combustion heater configured to heat the one or more combustion-heated reactors to a second target temperature range by combusting at least part of the reformate stream, wherein the at least one combustion heater is in thermal communication with the one or more catalysts of the one or more combustion-heated reactors;
- wherein the one or more combustion-heated reactors are configured to decompose additional NH3 to generate an additional reformate stream comprising H2, N2, and unconverted ammonia;
- and
- an adsorbent configured to adsorb the unconverted ammonia in at least one of the reformate stream or the additional reformate stream,
- wherein the system is configured to desorb the unconverted ammonia from the adsorbent using an exhaust of the at least one combustion heater to regenerate the adsorbent.
