| titleOfInvention | A kind of preparation method of the praseodymium zirconium solid solution for methane producing synthesis gas |
| abstract | The invention provides a kind of preparation method of the praseodymium zirconium solid solution for methane producing synthesis gas, belong to chemical preparation techniques field.Praseodymium, zirconium slaine is respectively water-soluble, make metal salt solution respectively, then mix and obtain mixed solution; Then add precipitating reagent to precipitate, then leave standstill aging, then with water carry out washing, suction filtration, until pH value is 7, obtained praseodymium zirconium solid solution precursor; Drying 8 ~ 24h is carried out at temperature is 90 ~ 200 DEG C; Preroast 2 ~ 4h at temperature is 250 ~ 350 DEG C again; Then through pulverize, then at temperature is 800 ~ 1000 DEG C roasting 3 ~ 10h, namely obtain praseodymium zirconium solid solution.It is that synthesis gas prepared by raw material that gained praseodymium zirconium solid solution is applied to methane.And anti-caking power and the cyclical stability of the carrier of oxygen can be strengthened; Promote the reactivity worth of two-step method producing synthesis gas and extend service life of the wherein carrier of oxygen.Method provided by the invention is simple, easily-controlled operation. |
