Description

technical field [0001] The invention relates to a device for producing hydrogen by electrolytic desulfurization of coal-water slurry. Background technique [0002] Coal-water slurry electrolytic desulfurization hydrogen production is to conduct DC pulse current electrolysis in the electrolytic cell through the coal-water slurry electrolyte, and generate hydrogen and carbon dioxide gas at the cathode and anode respectively; simultaneously remove the inorganic sulfur and organic sulfur in the coal, and produce low-sulfur refined coal or coal water slurry. Under the dual pressure of energy shortage and environmental pollution, hydrogen energy has long been included in the key breakthrough fields of scientific circles in various countries. According to reports at home and abroad, most of the research on this technology is still in the laboratory, and there is still a lack of efficient special equipment for hydrogen production by electrolytic desulfurization of coal-water slurry...
