For thermodynamically limited reactions such as CO2 hydrogenation to methanol, membrane reactors can represent a breakthrough of thermodynamic limits. However, due to performance degradation caused by issues like as mass transfer limitations by packed configuration and technical and cost problem of (by-)product selective membrane fabrication, it is difficult to manufacture on a large scale. The prospect of fabricating a large-scale methanol production membrane reactor is suggested in this study by using a partially solution-processable process which enabling mass production to manufacture a hollow fiber shaped alumina support with high specific surface area that serves as both a support and a catalyst in the membrane reactor. It has been confirmed that alumina hollow fiber supports generated from an aluminum-based metal-organic framework precursor feature both macro- and mesoporous structures that can mitigate mass transfer limitations and high specific area indicate that it can be used as a catalyst support for dispersion of metal. Hollow fiber shaped support-catalyst integrated copper-based catalysts for CO2 hydrogenation reaction were fabricated by wet impregnation method. |
