摘要：NOVELTY - The iron-based catalyst comprises metal doped spinel structure of ferroferric oxide nanometer crystals, where the dopant metal and iron atoms are provided in a mol ratio of 1-50:99-50. USE - Iron-based catalyst used preparing low carbon olefin in coal base synthesis gas (claimed). ADVANTAGE - The iron-based catalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing iron-based catalyst, which involves: (A) dissolving ferric chloride and doping metal precursor in an alcohol solvent mixture; and (B) mixing the formed mixture with carboxyl group-containing organic modifying agent for 8-72 hours at 200 degrees C to obtain an iron-based catalyst. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic scanning electron microscopic image of the iron-based catalyst.
