Description

technical field [0001] The invention relates to a system and process for producing oxygen-containing organic matter from carbon dioxide and coal. Background technique [0002] Energy is an important support for the development of the national economy. my country's energy endowment presents the characteristics of "rich in coal, poor in oil, and low in gas". The dependence on foreign oil and natural gas is high, and the international trade situation is complex and changeable, with many unstable factors. Therefore, it is of great practical significance to develop efficient and clean coal utilization technologies. Existing new coal chemical technologies usually refer to coal-to-oil, coal-to-methanol, coal-to-dimethyl ether, coal-to-olefins and coal-to-ethylene glycol, etc. The common point of these processes is to first gasify coal into synthesis gas, and then further utilize the synthesis gas into other chemicals. The process paths of these coal chemical industries are relati...
