含铬(钒)的NH4ZSM-5沸石分子筛
STUDY ON NH4ZSM-5 ZEOLITE CONTAINING CHROMIUM (OR VANADIUM)
【摘要】 在铵体系中用Cr3+或V3+取代Al3+,均能合成出NH4ZSM-5型沸石分子筛。采用多种测试方法表征,结果表明它们的结构与物化性质与文献上典型的ZSM-5沸石分子筛十分类似。
【Abstract】 NH4ZSM-5 zeolite has been successfully synthesized by using Cr3+ or V3+ instead of Al3+ in various ammonium systems. The so-prepared zeolites are characterized by X-Ray diffraction, lattice constants, transmission electronmicroscopy and infrared spectra, adsorption capacity,SiO2/Cr2O3 or SiO2/V2O3 ratio and ESR. It is found that their structures and physicochemical properties are very similar to those of typical ZSM-5 Zeolites.
