Abstract: Some properties and thermal decomposition of K3[Fe (C2O4)3] supported on HZSM-5 and HY zeolites have been studied by GC,MB,and IR methods.The Mo ssbauer spectrum and the infrared spectrum of K3[Fe(C2O4)3]/HY system were quite different from those of K3[Fe(C3O4)3], but for K3[Fe(C2O4)3]/HZSM-5 system, the differences were not roticeable. The decomposition mechanism of K3[Fe(C2O4)3]/HY system was quite different from that of the unsupported owing to the interaction between C2O42- and Al3+ and that between Fe3+ and the surface OH group of the support as well. The decomposition products were in highly dispersed state with iron cations. It was difficult to reduce them in H2 due to the strong effect of the surface of HY. In K3[Fe(C2O4)3]/HZSM-5 system the decomposition of K3[Fe(C2O4)3]was only partly modified because of the high Si/Al ratio and the weaker interaction between K3[Fe(C2O4)3] and the support.
