Jan 31, 2019 · Uniform SSZ-13 membranes with low defect concentrations were reproducibly synthesized on the 200 nm asymmetric tubular alumina supports in modified membrane gel. Single CO 2 , N 2 and CH 4 permeances dependent of pressure were predicted by the Maxwell-Stefan diffusion model and the predicted values were fitted well with the measured ones.Cited by: 2

Apr 28, 2006 · Strong and permeable macro‐porous α‐Al 2O 3 membrane supports are made by colloidal filtration of 20 vol% dispersions of α‐Al 2O 3 with an average particle size of 600 nm. Intact compacts with very good surface quality were obtained at an optimum pH of 9.5 and dosage of 0.2 wt% ammonium aurintricarboxylate (Aluminon), based on dry alumina.
