It is reported that the first synthesis of MCM-22 zeolite by the vapor-phase transport (VPT) method and the comparison in the morphologies of MCM-22 synthesized by the VPT and hydrothermal synthetic (HTS) methods. In the VPT method, pure MCM-22 zeolite was crystallized at 150°C for 5 days and at 175°C for 3 days. The morphology of MCM-22 zeolite crystallized by the VPT method was sphere which is an agglomerate of hexagonal thin plates having about 3-5 μm in width with less than 100 nm thick. Such morphology was similar to MCM-22 zeolite synthesized by the HTS method under static condition. The crystallization by the VPT method with the addition of HMI onto dry gel gave smaller MCM-22 crystals consisting of thin plates with 12 μm in width.
