[1D12] Development of a Hollow Fiber Membrane Reactor for Selective Water Removal in Chemical Reactions
Keywords:membrane, catalysis, reaction engineering
The technology of selectively removing byproducts generated during chemical reactions has evolved in various forms, not only to increase yield through thermodynamic equilibrium shifting but also to extend catalyst lifespan and suppress undesired side reactions. However, most pervaporation membranes including zeolites, which lose their selectivity at higher reaction temperatures, had limitations for practical application. In this study, a polybenzoxazole polymer membrane was fabricated in a hollow fiber form and incorporated with a catalyst to develop a reactor for continuous water removal. This reactor was utilized in various reactions that generate water as a byproduct. The model reactions included reverse water-gas shift reaction, low-temperature methane oxidation reaction, and Fischer-Tropsch synthesis reaction, aiming to investigate how the effects of pervaporation membranes are manifested in each reaction.
