Selective hydrocondensation of CO to light olefins with alumina-supported iron catalysts

If alumina supports for iron catalysts are changed, it is possible to enhance the activity by two orders of magnitude and to increase light olefin selectivity from 10% to 40%, but so far the most active catalysts are the least selective.

Carbon monoxide hydrocondensation on iron catalysts prepared from metal carbonyl compounds

The iron/alumina catalysts prepared by the impregnation of Fe(CO)₅ on the support have properties quite different from those of the conventional catalysts in the CO+H₂ reaction. However, the preparation procedure or the activation of the solid has a decisive effect on the activity, selectivity and stability.
