Improving sapo-34 membrane synthesis
Witryna7 gru 2024 · In this work, 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 × 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.
