| Research Abstract |
We have successfully developed a preparation method for size-controlled synthesis of MFI, MOR and FAU zeolites in organic-structure-directing agents (OSDA) free condition. Nano-sized zeolite possesses advantages, such as low-diffusion resistance for hydrocarbons and high external surface area. By applying the advantages, a ZSM-5 nanocrystal layered membrane was prepared and used as a catalytic membrane for acetone-to-olefin reaction. As compared with a conventional fixed-bed reactor, the catalytic membrane exhibited a high acetone conversion and high olefin yields.
