CO Hydrogenation on Supported Ultrafine Iron Particle Catalysts Prepared by Gas Evaporation Method

Ultrafine iron particles prepared by the gas evaporation method were found to be able to become high active and relatively stable catalysts for CO hydrogenation, simply by mixing them with supports, under the conditions of Fe contents less than 10 wt% and reaction temperatures below 250 °C. The sequence of catalytic activity, depending upon the kind of support, was as follows; TiO2(JRC-3,4,5 and Wake, M) > HZSM-5(US) > SiO2(M) > Al2O3(M) > NaZSM-5(M).
