Most zeolite membrane s are inherently hydrophilic and thus preferentially permeate water. This characteristic has led to the commercial application of zeolite membranes in molecular separations\, particularly for organic solvent dehydration. H owever\, hydrocarbon-selective membranes are highly desirable for applicat ions such as bioseparations and membrane reactors aimed at enhancing produ ct yields. This paper presents a synthesis strategy to enhance the hydroph obicity\, and thereby hydrocarbon selectivity\, of zeolite membranes by in creasing the Si/Al ratio and crystallinity\, while maintaining high permea bility through membrane thinning. The approach involves synthesizing zeoli te membranes on non-aluminum supports (such as porous yttria-doped zirconi a and stainless steel) as well as on alumina supports\, incorporating a hi erarchical mesoporous pure-silica zeolite intermediate layer between the a lumina support and the top zeolite separation layer. This intermediate ze olite layer plays two critical roles: it prevents Al ion migration from th e alumina support into the synthesis mixture\, and it provides a mechanica lly robust yet permeable foundation that favors nucleation over crystal gr owth\, enabling the formation of a thin\, uniform top layer. These efforts culminate in the synthesis of super-hydrophobic MFI-type zeolite membrane s. The hydrophobic nature of these membranes results in negligible impact from the presence of steam during gas separation\, as demonstrated using H₂/CO₂ binary and H₂/CO₂/H₂O ternary gas mixtures at elevated te mperatures (300–550 °C). In contrast\, water vapor significantly degr ades the separation performance of hydrophilic zeolite membranes. The supe r-hydrophobic MFI zeolite membranes exhibit high selectivity for hydrocarb ons over water\, in particular\, ethanol or methanol over water. \n\nBiosk etch: \nJerry Y.S.
