The ZSM-22 zeolite was synthesized by like solid-phase method with solid silicon as a silicon source. The effects of silicon source type, seed, alkali/silica ratio, crystallization temperature/time and stirring rotational speed in the crystallization on the synthesis performance were investigated. The result indicate that the ZSM-22 zeolite with a high crystallinity can be prepared under the optimum conditions (i.e., n(KOH)∶n(Al2O3)∶n(SiO2)∶n(H2O)∶n(DAH)∶n(seed) of (0.150-0.180)∶0.012 5.000∶1.000∶(5.100-7.900)∶0.300∶0.068, crystallization temperature of 443 K, crystallization time of 16 h and stirring rotational speed of 20 r/min). Compared to the conventional hydrothermal method, the like-solid-phase method can reduce the crystallization time and increase the solid content of feeds and product yield. The zeolites synthesized by hydrothermal and like-solid-phase method were characterized by X-ray diffraction, specific surface area measurement, pyrolysis infrared spectrometry and scanning electron microscopy, respectively, showing that they have differences in the acidity distribution and pore structure.
