The effect of flower-like tatania towards characteristics and performance of polysulfone mixed matrix membrane
For ages, the polymeric membrane such as PSf is widely used in liquid separation for various application as the polymer itself offer versatile and attractive properties. However, due to strong hydrophobic nature of PSf property that create serious fouling problem to most of the separation process, …

Carbon Dioxide Gas Separation from Syngas to Increase Conversion of Reverse Water Gas Shift Reaction via Polymeric and Mixed Matrix Membranes
Membranes are a promising, effective and energy efficient separation strategy for effluent gases in the Reverse Water Gas Shift (RWGS) reaction to increase the overall conversion of CO2 to CO. This process involves a separation and recycling process to reuse the unreacted CO2 from the RWGS reactor. …
