【Abstract】 Ga containing ZSM-5 type zeolite with a ratio of SiO2/Ga2O3 being 60-38 has been synthesized from water glass,gallium trichloride,1,6-hexanediamine HXDA and water at 150-170℃ without addition of crystal seeds and directing agent.The X-ray diffraction pattern showed that Ga-ZSM-5 type zeolite similar to zeolite ZSM-5.The cell parameters.a=20.2lA b=20.04A,c=13.47A,were obtained by step scanning technique.An electron probe analysis was conducted,which shows gallium entered the framework of the zeolite.The adsorption proper-lies,acidity,thermal stability and IR spectra were also determined.更多还原
