| 简介 |
FIELD : chemistry.
SUBSTANCE : invention relates to production of a catalyst for producing synthetic gas during carbon dioxide conversion of methane. The catalyst for carbon dioxide conversion of methane for producing synthetic gas is a cerium-zirconium based composite support containing one or two metals selected from rare-earth elements such as Pr, Sm, La or any combination thereof; the active component is a platinum group metal selected from Pt or Ru; Pt or Ru with Ni additives; La with Ni additives; La with Ni additives, Pt or Ru, wherein the catalyst has the general formula M1M2M3[AxByCe0.35Zr0.35]O2, where : x equals 0-0.3, y equals 0-0.3, A and/or B are selected from rare-earth metals Pr, La, Sm, Mi is selected from platinum group metals Pt or Ru, M2 denotes Ni; M3 denotes La, provided that if content of metal M1=0, then content of M2≠0, and if content of M2=0, then content of M1≠O. Described is a method of producing synthetic gas during carbon dioxide conversion of methane using the catalyst described above.
EFFECT : high activity of the disclosed catalysts, which enable to conduct carbon dioxide conversion of methane or natural gas at high loads of feeding the reaction mixture, ie, at short contact time.
