Thin and high-quality SSZ-13 membranes were synthesized by the steam-assisted conversion (SAC) method for the first time. More than 95% gel/solution was saved for membrane growth compared with conventional hydrothermal synthesis. Another advantage for the SAC method was that the competitive crystallization between the bulk solution and support was eliminated. The thickness of SSZ-13 membranes was well controlled from 1.2 to 3.0 μm by the dilution of sucked solution and synthesis time. Three membranes prepared under optimized conditions displayed N 2 permeances of (1.4 ± 0.12) × 10 −7 mol m −2 s −1 Pa −1 (∼418 GPU), N 2 /CH 4 selectivities of 14.8 ± 0.45 and a separation index of 0.19 ± 0.02 mol m −2 s −1 at 298 K, and 0.2 MPa pressure drop for an equimolar N 2 /CH 4 mixture. The membranes synthesis by the SAC method had a good reproducibility. Such separation performances of current SSZ-13 membranes were beyond the upper bound for N 2 /CH 4 separation among the reported membranes. The influences of temperature, pressure drop, and feed flow rate on separation performance of the membranes were investigated. High-pressure N 2 /CH 4 separation was also reported using SSZ-13 membranes at the pressure drop up to 2.5 MPa.

“…Defects usually refer to the intercrystalline pores with a larger size than the intracrystalline pores (i.e., zeolite channels), which originate from either the linear expansion difference of support and zeolite materials or the insufficient zeolite crystal growth ( Al-Akwaa et al., 2021 ; Vaezi et al., 2018 ). The gas diffusion is promoted with more defects or an enlarged defect at the cost of selective permeation.…”
