ABSTRACT:

Objectives are to develop active, stable iron Fischer-Tropsch catalysts for use in slurry-phase synthesis reactors and to develop a scaleup procedure for large-scale synthesis of such catalysts for process development and long-term testing in slurry bubble-column reactors. For a H(sub 2)-CO in molar ratio of 0.5 to 1.0, catalyst performance target is 88% CO+H(sub 2) conversion at a minimum space velocity of 2.4 NL/hr/gFe, with no more than 4% methane/ethane selectivity and 1% conversion loss per week. During this period, it was found that the performance of the slurry-phase iron and copper oxide-based catalyst depends on the amount of K. Five catalysts with differing K contents were studied. The catalysts with the lowest K were more active than the ones with higher K levels. The one with the middle K level was judged best.
