Abstract

ZK-5 (KFI) molecular sieve was synthesized in the K2O:SrO: Al2O3:SiO2:160 H2O:THF system using conventional hydrothermal heating. Effect of tetrahydrofuran (THF) was investigated. Products were characterized by XRD, TGA, FESEM, EDX and TPD-MS. THF influences the crystallinity and crystal size of ZK-5. The molar ratio of THF/Al2O3 from 0.4 to 1.0 gives the best results in terms of crystallinity (measured by XRD) and purity for the prepared ZK-5. Crystal size of ZK-5 zeolite is reduced by the presence of THF.
