Methanol steam reforming hydrogen production technology has been greatly developed and widely used due to its advantages of small investment, low production cost, advanced technology, easy separation of product hydrogen, and easy transportation of raw material methanol. Its special Cu-based catalyst has the characteristics of high activity and good hydrogen selectivity, so the process has good technical advantages and application prospects. Methanol decomposition hydrogen production technology can obtain two product gases, hydrogen and carbon monoxide, and the catalyst used can directly use Cu-based catalysts for hydrogen production by methanol steam reforming, so it is easy to be applied well. At present, methane decomposition hydrogen production technology shows good application prospects in chemical industry, metallurgy and other industries. Methanol partial oxidation and partial oxidation reforming hydrogen production technology can meet the heat required by the process itself because the reaction itself releases heat, and it has attracted more and more attention from researchers. This process technology can be applied to hydrogen fuel cells and portable methanol miniaturized hydrogen production devices. For example, in its application in hydrogen fuel cell vehicles and miniaturized hydrogen production devices, it has the following advantages over methanol steam reforming hydrogen production technology.: (1) It can be quickly heated to the required operating temperature after ignition, and the entire reactor system can be started easily and quickly. ； (2) Use liquid fuel directly, eliminating the need for vaporization devices ； (3) Good dynamic response when load changes. When the vehicle is accelerating, that is, when the battery pack requires more hydrogen flow to increase power output, this system can quickly change hydrogen production by changing the fuel flow rate as long as it is within the reformer's design capacity range. In the application of hydrogen fuel cells and miniaturized hydrogen production devices, methanol partial oxidation hydrogen production technology shows obvious advantages. At present, its related research has been actively carried out around the world. The main problems that need to be solved include:: (1) In the inlet part of the reactor, due to the influence of methanol combustion, the catalyst here is prone to high-temperature sintering or coking, which will cause rapid deactivation of the catalyst. ； (2) In order to avoid burning too much methanol and reducing fuel economy, the operating temperature of methanol reforming needs to be lower than the operating temperature of traditional reforming reaction, which will lead to a decrease in methanol conversion rate. ； (3) When the operating temperature of the reformer is low, the conversion rate of the water gas shift reaction will be reduced and the CO content in the reformed gas will increase. It can be seen from the above aspects that the key technical problem that needs to be solved at present is the performance of the catalyst. It is urgent to develop a new methanol partial oxidation catalyst with good thermal stability, high selectivity and low temperature activity. This is also an important problem because the technology is still in the technical research stage and has not yet been applied on a large scale.
