Description

technical field [0001] The invention belongs to the technical field of coal liquefaction, and in particular relates to an electrolysis device for coal liquefaction. Background technique [0002] In the modern sustainable development industry, the demand for energy continues to increase, making the production of energy far from meeting the demand. Among them, petroleum is an important energy source for economic development, but my country's petroleum resources are far less than coal resources, so the development and application of coal liquefaction technology has become a trend. Coal liquefaction is a technology that converts solid coal into liquid fuels, chemical raw materials and products through chemical processing. The direct coal liquefaction process refers to the cracking and processing of coal molecules under the action of catalysts and solvents at high temperature and high pressure. Hydrogen is directly converted into liquid fuel, and then further processed and refin...
