Description

technical field [0001] The invention belongs to the technical field of performance detection, and in particular relates to a catalytic performance testing device and a testing method of an ortho-parahydrogen reaction catalyst. Background technique [0002] Liquid hydrogen is an important strategic resource for the development of aerospace and hydrogen energy industries. With the development of my country's aerospace industry and the continuous advancement of the lunar exploration and fire detection program, the demand for heavy-duty rockets is increasing, and the demand for liquid hydrogen, which is the best energy source for heavy-duty rocket liquid hydrogen-liquid oxygen engines, continues to increase. [0003] Hydrogen molecules are composed of two hydrogen atoms. Due to the different spin directions of the two hydrogen nuclei, there are two states of hydrogen, positive and secondary. The nuclei of orthohydrogen spin in the same direction, and the nuclei of parahydrogen ...
