Description

technical field [0001] The invention relates to an electrochemical hydrogenation device and method, belonging to the technical field of chemical industry. Background technique [0002] Hydrogenation reaction is an important process technology in chemical production process. Straight-run gasoline, diesel, jet fuel and other oil products usually need hydrogenation reaction to remove sulfur, nitrogen, etc.; biomass diesel generally has the problem of high oxygen content, and the quality of biomass oil can be effectively improved by hydrogenation treatment. Due to the low activity of the hydrogenation reaction, a higher pressure is usually required to maintain the partial pressure of hydrogen to make the reaction proceed forward. At present, the conventional hydrogenation method needs to use a high-temperature and high-pressure reactor to carry out the hydrogenation reaction under the conditions of 6-18MPa and 350-450°C. The relatively harsh reaction conditions require complex...
