Experiments were performed on ZSM-5 catalyst impregnated with 11.1% of iron (A) or 5.6% of iron and 4.5% of cobalt (B) and on Silicalite, a molecular sieve form of silica, impregnated with 13.6% of iron (C), 7.8% of iron and 0.9% of potassium (D), or iron and manganese in fixed-bed or continuous stirred tank laboratory reactors. Zeolite acidity played an important part in forming aromatics from synthesis gas (2:1 or 1:1 hydrogen/carbon monoxide ratio) by bifunctional catalysts, as demonstrated by comparison of the product slates from the A and C catalysts. The transition metal component impregnated into the zeolite played an important part in selectivity, as demonstrated by the liquid phase products from the A and B catalysts. D catalyst had an exceptionally high selectivity for production of C/sub 2/-C/sub 4/ olefins. The experiments were carried out at 280/sup 0/-300/sup 0/C and 21 bar, and magnetic studies were performed to characterize the transition metal component and detect the formation of bimetallic iron-cobalt clusters.
