Abstract
A para-orthohydrogen conversion device comprises a vortex tube. The vortex tube may include an inlet disposed at a first end of the vortex tube, a catalyst disposed on the interior wall of the vortex tube, a first outlet comprising an opening on the perimeter of a second end of the vortex tube, a stopper disposed at the center of the second end of the vortex tube, and a second outlet disposed on the first end of the vortex tube. A method includes converting parahydrogen to orthohydrogen via the catalyst and rotational force as hydrogen gas moves through the vortex tube such that cooled parahydrogen-rich gas or liquid hydrogen accumulates near the center of the vortex tube.
