Valuable conversion products are produced from CO and H₂ in the presence of Fe catalysts by contacting the CO and H₂ in synthesis proportions and under synthesis conditions with catalyst particles containing ferrosilicon from which about 1.5-3 wt. % of silicon based on the total catalyst has been removed by etching with a caustic alkali solution.
