A catalyst for oxidative coupling of methane to C 2 hydrocarbons uses oxide A a O x as an active component, an oxide auxiliary B b O y is added on the basis of the active component, and the active component of the catalyst and the auxiliary are supported in On the carrier S, the mass percentage content of the active component A a O x in the catalyst is 0.5-5.0%, the addition amount of the auxiliary agent B b O y is B:A metal molar ratio=1:5-1:50, and the rest are vector. The invention utilizes the atomic layer deposition method to immobilize the active components on the surface of the carrier, realizes the efficient conversion of methane into C2 hydrocarbons such as ethylene and ethane at low temperature, and the catalyst exhibits excellent performance. The invention combines the advantages of low-temperature nanomaterials and carrier support, and has high utilization rate of active components, low reaction temperature and good stability. |
