Summary: We propose a new method that utilizes HDPE ultrafiltration hollow fibers as dehumidification membranes. These membranes have a wide range of applications and can also recover water. To address the issue of large pores in low-cost substrates like HDPE, we filled the pores with hydrogels made from viscous solutions. The resulting pore-filled membranes showed good water vapor separation capabilities.

Summary: Hydrogen isotope separation can be achieved using a palladium (Pd) membrane due to the different solubility, diffusivity, and permeability of protium (H) and deuterium (D) in Pd. The permeability of H (k(H2)) and D (k(D2)) were studied at various temperatures and pressures using a Pd membrane separation unit. The selectivity of the Pd membrane towards H2 increases with temperature but decreases at higher temperatures due to the influence of competitive transport and isotope diffusion.

Summary: In this study, nanocomposite membranes with uniform dispersion of amorphous PANI nanofibers were prepared using different concentrations of Pebax 1657 and PANI. The membranes exhibited defect-free structures and lower crystallinities. As the nanofiber loading increased, the CO2 permeability and selectivity of the membranes increased, surpassing the Robeson upper bound limit and approaching the values in 2008. The CO2 permeability and ideal CO2/CH4 selectivity of the nanocomposite membrane loaded with 10 wt.% PANI nanofibers increased to 121.2 Barrer and 33, respectively, showing increments of 64% and 40%.

Summary: Studying Al2O3-supported Pt/Pd bimetallic catalysts using in situ atmospheric pressure and ex situ transmission electron microscopy revealed that significant metal vaporization and Pd diffusion play key roles in catalyst structural evolution. Under oxidizing conditions, a decrease in both the number of metal particles and the surface area to volume ratio was observed. Furthermore, some metal particles that diffuse away can be regenerated and reappear on the catalyst support surface under reducing conditions.

Summary: The use of ammonia as a hydrogen carrier can be improved with the use of a membrane reactor, which allows for ammonia decomposition and hydrogen separation in one device, providing efficiency and compactness advantages. Ceramic-supported double-skinned Pd-Ag membranes have shown excellent performance for hydrogen separation but suffer from sealing and mechanical stability issues. To overcome these limitations, metallic supported Pd-based membranes are suggested. In this study, a Pd-Ag membrane was prepared on a low-cost metallic support and tested for ammonia decomposition in a membrane reactor, achieving high NH3 conversion and H2 recovery rates. These results indicate potential as a substitute for ceramic-supported alternatives.

Summary: This study experimentally compares the performance of a packed bed membrane reactor (PBMR) and a conventional packed bed reactor (PBR) for CO2 conversion to dimethyl ether (DME). The PBMR outperforms the PBR in most conditions, with improvements in CO2 conversion and DME yield. Higher sweep gas-to-feed ratios increase water removal and improve PBMR performance, but result in the removal of other products. Higher temperatures selectively enhance the rWGS reaction but reduce DME yield due to methanol loss. Higher transmembrane pressures are not beneficial for PBMR performance. Reactor models developed in previous studies accurately describe the performance of both reactors and can be used for further optimization and simulation.

Summary: The effect of carbonization temperature on the performance of carbon membranes in vapor/gas separation was assessed. It was found that the nature of functional groups and pore structure changes with carbonization temperature. The presence of ultra-micropores enhances water permeance but reduces hydrophilicity. Gas permeation is mainly influenced by the pore size distribution.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
