AbstractHigh-silica MFI zeolite membranes supported on porous a-alumina discs were prepared by a seeded secondary growth method,using tetrapropylammonium hydroxide(TPAOH) as organic template.First,nanocrystals were deposited on rough α-AI2O3 discs by a spin-on pr

Other Abstract采用旋涂法在粗糙的α-Al2O3载体片上制备出较完备的分子筛晶种层;以四丙基氢氧化铵(TPAOH)为有机模板剂,通过调控合成液的H2O/Si摩尔比,实现了对分子筛晶体面内优先生长的调控;经过三次水热合成得到致密交联的hOh-轴取向高硅MFI分子筛膜,膜厚约为8μm(包括~5μm致密层和~3μm过渡层)。采用先低温加氢裂解后低温空气氧化的两步法脱除工艺,有效脱除了分子筛膜内的有机模板剂。相比于传统高温煅烧法,该法可以避免分子筛膜因脱除模板剂而形成的较大晶间缺陷。因而采用低温两步法脱除模板剂的分子筛膜片在30
