Abstract
The present embodiments include systems and methods for converting ortho hydrogen to para hydrogen using, for example, a heat exchange wall that may be coated with a catalyst material.
Claims24
A device for converting ortho hydrogen to para hydrogen comprising:
- a heat exchanger comprising an integrated heat removal system;
- a catalytic material coated on the heat exchanger, wherein the catalytic material is configured to convert ortho hydrogen to para hydrogen;
- a flow system configured to flow hydrogen through the heat exchanger upon the hydrogen contacting the catalytic material;
- a cooling system configured to at least partially remove heat from an ortho hydrogen to para hydrogen conversion;
- a monolith within the flow system, wherein the monolith comprises one or more channels for flowing hydrogen therethrough and wherein the monolith is configured such that ortho hydrogen and para hydrogen can flow through the one or more channels one or more times;
- a permanent magnet;
- an electromagnet;
- and
- a magnetocaloric material between the permanent magnet and the electromagnet, wherein the permanent magnet and the electromagnet are operably connected to the monolith and configured to create a magnetic field that (1) accelerates conversion of the ortho hydrogen to the para hydrogen, (2) removes heat through a magnetocaloric effect, or (3) both (1) and (2).
