The system comprises a vaporizer, a methanol-to-hydrogen reactor and a heat exchanger, the vaporizer is communicated with the methanol-to-hydrogen reactor through a first pipeline, the methanol-to-hydrogen reactor is communicated with the heat exchanger through a third pipeline, and the heat exchanger is communicated with the vaporizer through a second pipeline. A second pipeline is arranged between the first pipeline and the heat exchanger, and safety interlocking control parts are arranged on the first pipeline and the second pipeline. The device is ingenious in conception, compact and reasonable in layout and high in automation degree, when the methanol-to-hydrogen reactor is started, liquid water is effectively prevented from entering a catalyst in the methanol-to-hydrogen reactor in the methanol water heating and cooling processes, high-temperature steam enters the methanol-to-hydrogen reactor, and the safety of the reaction process is guaranteed.
Description
technical field [0001] The invention relates to the technical field of methanol production, in particular to a system and method for preventing the pulverization of a catalyst for methanol hydrogen production from water ingress. Background technique [0002] Methanol hydrogen production is widely used in industrial production. Copper-based catalysts have low reaction temperature and good activity and have been widely used as catalysts for methanol hydrogen production. In the methanol hydrogen production process, methanol and water are vaporized and superheated in a liquid state to become steam at 220 ° C ~ 280 ° C and enter the methanol hydrogen production reactor. The methanol hydrogen production reactor is filled with a copper-based catalyst, and the methanol water vapor reacts to form H 2 and CO 2 mixed gas. During normal operation, the methanol water entering the methanol hydrogen production reactor is superheated steam, and there will be no liquid water, but at the be...
