Special Issue Information

Dear Colleauges,

Professor Moises A. Carreon focused on mission critical gas separations and provided bedrock research on the design of porous crystalline materials [1]. He became convinced (and equally convincing) that nearly any gas mixture could be separated without massive energy inputs during cryogenic distillation [2]. The fundamental strategies for separating gas mixtures over porous crystalline membranes—adsorption, diffusion, molecular sieving—guided his synthetic designs and resulted in many unique discoveries ranging from inorganic [3], metal organic [4], and purely organic membranes [5]. His latest research efforts were focused on process intensification using membrane technology [6].

This Special Issue aims to provide state-of-the-art contributions on critical gas membrane separations, which were Moises’ main career focus and leading research area. Submissions are not limited to separation applications, but can include membrane material designs for separation purposes and membrane applications, including process intensification.

Moises was a man of great talent and ingenuity. He was held in the highest regard by his peers and known for his kindness, collegiality, grit, creativity, diligence, and collaboration. He was an avid supporter of minority STEM students and was a champion for Diversity and Inclusion at the Colorado School of Mines. He touched many people’s lives, and he left a lasting positive impact on them. He was a person who was so alive in every way. He loved everything he did, whether it was work or personal, and he truly lived his life to the fullest. Though he was very young when he left us, he contributed with many teachings and an important legacy to science and engineering. He will be sorely missed by his students, colleagues, friends, and family.

In this study, we investigate the influence of cold-plasma-induced enhanced performance and efficiency of SAPO-34 membranes in the separation of CO2 and CH4 mixtures. Placing the herein presented research in a broader context, we aim to address the question of whether cold plasma can significantly impact the membrane performance. We subjected SAPO-34 membranes to plasma mild disturbances and analyzed their performance in separating CO2 and CH4. Our findings reveal a notable enhancement in membrane efficiency and sustained performance when exposed to cold plasma. The pulsed plasma separation displayed improved structural integrity, and the experimental results indicated that the linear structure of CO₂ facilitates the distortion of electron clouds in response to the electric field, a property known as polarizability, which aids in effective separation. Plausible mechanistic insight indicated that the intermolecular forces facilitated an integral role in SAPO-34 membranes exhibiting strong electrostatic interactions. In conclusion, our research highlights the potential of cold plasma as a promising technique for improving the performance of SAPO-34 membranes in gas mixtures at atmospheric pressures, providing valuable insights for optimizing membrane technology in carbon capture and gas separation applications.

Pervaporation is an energy-efficient alternative to conventional distillation for water/alcohol separations. In this work, a novel CHA zeolite membrane with an increased Si/Al ratio was synthesized in the absence of organic templates for the first time. Nanosized high-silica zeolite (SSZ-13) seeds were used for the secondary growth of the membrane. The separation performance of membranes in different alcohol–aqueous mixtures was measured. The effects of water content in the feed and the temperature on the separation performance using pervaporation and vapor permeation were also studied. The best membrane showed a water/ethanol separation factor above 100,000 and a total flux of 1.2 kg/(m2 h) at 348 K in a 10 wt.% water–ethanol mixed solution. A membrane with high performance and an increased Si/Al ratio is promising for the application of alcohol dehydration. Full article
