Series of zeolite-supported iron-containing catalysts with weight percent iron (% Fe) varying from approx. 1 to approx. 17% Fe have been prepared from Fe/sub 3/(CO)/sub 12/ and the synthetic zeolites ZSM-5, mordenite and 13X by an extraction technique. The zeolites ZSM-5 and mordenite were used in the acid form, 13X in the sodium form. The catalysts were characterized by a variety of techniques including infrared spectroscopy, X-ray powder diffractometry, X-ray photoelectron spectroscopy, ion-scattering spectrometry and Mossbauer spectroscopy. All catalysts contain highly dispersed, small particle-sized ..gamma..-Fe/sub 2/O/sub 3/ with a small amount of the iron (0.6 to 1.5% Fe depending on the support) located in the pores of the support. Evaluation of the catalytic ability of some of these materials for synthesis gas conversion was conducted at 280/sup 0/C and 300/sup 0/C by using a fixed-bed continuous flow microreactor. All catalysts evaluated produce significant quantities of hydrocarbons. The distribution of hydrocarbons varies, depending upon the support used, for catalysts with similar weight percent iron. For the liquid hydrocarbons, Fe/ZSM-5 produces the highest percentage of aromatics, Fe/mordenite produces the highest percentage of olefins, and Fe/13X produces the highest percentage of saturates. The effect of support acidity and pore structure on hydrocarbon product distribution is discussed.
