甲醇蒸汽重整制氢过程强化研究进展

Hydrogen as a clean energy can help us solve the problems faced by traditional energy.The best way to achieve carbon compliance and solve the current environmental and climate problems is to vigorously develop green hydrogen production technology. Green hydrogen will also become an inevitable trend in the development of hydrogen energy in the future. Methanol is considered to be a favorable substitute for fossil fuels due to its abundant sources, lower price, easier availability, higher energy density and lower working temperature. The methanol steam reforming to produce hydrogen at a lower reaction temperature (150 C-300 C), lower energy consumption， higher hydrogen production rate, lesser product pollution is, and the technology is relatively mature. In this paper, the current research status of the intensification technology of methanol steam reforming (MSR) process is reviewed. And the current characteristics and research progress of MSR microreactors are summarized. Introduced the research on the modification of common catalysts by loading different mass fractions of metals and using other catalyst supports, The conclusion is different catalyst application methods will also affect the reaction process. Monolithic frame catalysts are mostly used in tubular reactors. Coated catalysts are widely used in microreactors to create smaller reactors with better hydrogen production performance. Among other technologies for enhancing the MSR process, the research of a new type of solar thermal reforming hydrogen production reactor filled with phase change heat storage medium is the main content of this paper.
