| titleOfInvention | Iron catalyst used in butadiene production through n-butylene oxidation dehydrogenation, and preparation method and application thereof |
| abstract | The invention relates to an iron catalyst used in butadiene production through n-butylene oxidation dehydrogenation, and a preparation method and an application thereof. The catalyst comprises Fe as a main component, and a co-catalyst comprising Mg, Zn, and other elements. The catalyst is composed of, by mass, 48.80-60.53% of Fe, 0.01-18.00% of Mg, 0-15.00% of Zn, 0-5.00% of other elements, and balance of oxygen element. The catalyst is prepared with a precipitation method. The catalyst is applied in butadiene production through n-butylene oxidation dehydrogenation by using an adiabatic fixed bed. Application conditions comprise: adiabatic fixed bed material inlet temperature is 260.0-445.0 DEG C; molar ratio of inlet oxygen to n-butylene is 0.42-0.90; molar ratio of inlet water to n-butylene is 12.0-25.0; inlet n-butylene volume space velocity is 180-600h<-1>, and an adiabatic fixed bed material outlet temperature is 457.0-650.0 DEG C. Compared with prior arts, the catalyst provided by the invention is suitable for an adiabatic fixed bed, and has the advantages such as high butadiene selectivity, good catalyst reaction stability, and the like. |
