Improving sapo-34 membrane synthesis
Witryna1 maj 2024 · In this perspective, gas separation using membranes and gas hydrates is briefly reviewed, and the challenges of developing an integrated gas hydrate-membrane process are discussed. Such a process could be an energy efficient approach to reduce the costs associated with natural gas purification. Witryna1 mar 2024 · In this communication, we demonstrate the ability of a zeolite membrane, denoted as SAPO-34 to effectively capture Xe from air. Specifically, SAPO-34 membranes showed air permeances as high as 2.3 x 10 -7 mol/m 2 s Pa (690 GPU) and separation selectivities as high as 30.1 for a molar feed of 9:1 air/Xe.
