摘要：NOVELTY - Preparation of syngas catalyst involves adding catalyst containing active component, carriers and additives, agitating raw material powder with organic solution, obtaining solution, providing solution of an iron source using peristaltic pump, blowing gas together thermostatic heating equipment segment, grinding carrier, mixing the obtained sediment, calcining, obtaining desired catalyst, adding iron-containing compound into the active group and crystallizing precursor of the iron source with water and metal oxides. USE - Preparation of syngas catalyst is used for preparing light olefins. ADVANTAGE - The syngas catalyst is efficiently and economically prepared. DETAILED DESCRIPTION - Preparation of syngas catalyst involves adding catalyst containing 15-40 wt.% an active component, 30-85 wt.% carriers and 0-30 wt.% additives, grinding 10 %mass catalyst structure directing agent, active ingredient, additives and structure-directing agent to sieve of 40-200 meshes, agitating raw material powder with an organic solution into iron source solution for 15 times, obtaining solution evenly, providing solution of an iron source using a peristaltic pump at flow rate of 10-300 ml/hour into the pump, blowing gas together thermostatic heating equipment segment at flow rate of 10-300 L/hour and 200-2000 degrees C, collecting the product gas through outlet of cooler deposition, grinding carrier to sieve of 40-300 meshes, mixing the obtained sediment at 200-800 degrees C, calcining for 2-20 hours, obtaining desired catalyst, adding iron-containing compound into the active group and crystallizing precursor of the iron source with water and metal oxides. The carrier is alumina, titanium oxide, silica, magnesium oxide, silicon carbide, carbon, manganese oxide, zinc oxide, thorium oxide, mesoporous molecular sieves or zeolite. The additive is chosen from lithium, sodium, potassium, cesium, copper, cobalt, nickel, zinc, sulfur, molybdenum, manganese, rubidium, iridium, titanium, scandium, cerium, zirconium, magnesium, vanadium, tungsten and chromium. The gas is argon, nitrogen and helium. The organic solution is chosen from methanol, ethanol, ethylene glycol, N-propanol, isopropanol, glycerol, pentanol, n-hexane, toluene, xylene, chloroform, benzene, acetone, acetonitrile, trioctylphosphine oxide, ethylenediamine, triethylamine, triethanolamine or polyether. The structure-directing agent is chosen from amino acid, urea, picoline, quinoline, aniline, octadecylamine, cetyl trimethyl ammonium bromide, benzyl alcohol and polyethylene glycol.
