Description

technical field [0001] The invention belongs to the technical field of hydrogen production by electrolysis of water and liquid organic hydrogen storage, and specifically relates to an integrated device and control method for hydrogen production by pure water and direct liquid hydrogen storage and hydrogenation. Background technique [0002] The current electrolytic hydrogen production method is to collect the produced hydrogen in a high-pressure gaseous form. The traditional process of hydrogen production and hydrogen storage is to first produce hydrogen to generate hydrogen gas, then catalyze the hydrogen gas to generate hydrogen protons, and then inject the hydrogen protons into liquid organic hydrogen storage materials. Not only is the production process complicated, but it also greatly reduces energy efficiency and increases more energy consumption. The current existing liquid organic hydrogen storage and hydrogenation technologies all use traditional chemical reactors ...
