摘要: MeAPSO-34 molecular sieves were synthesized successfully with metal ions of Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mg, Ca, Sr, and Ba (Me/Al2O3=0.05). IR, NH3-TPD measurements fixed bed MTO performances all the samples carried out in comparison SAPO-34. The results illustrated that incorporation had great effects on structure acidity sieves. It was interesting most exhibited effective enhancement performance. Especially, Co2+, Zn2+ Mg2+ showed promising modification effect for catalysts.
