通过晶体转化的方法合成封装Pt的方钠石Pt/SOD。封装Pt的方钠石通过以下两步结晶的方法合成,在100℃结晶12h,120℃结晶144h,130℃结晶96h,140℃结晶60h,150℃结晶42h160℃结晶30h。样品在硫化氢的毒化前后表现了良好的加氢活性。通过X射线衍射法检测样品相的结晶形式。通过H2-TPD表征给体相Pt/SOD与受体相HZS-5之间的氢溢流。
Pt-encapsulated sodalite Pt / SOD was synthesized by crystal transformation. The Pt-encapsulated sodalite was synthesized by the following two-step crystallization method. Crystallization at 100 ℃ for 12h, crystallization at 120 ℃ for 144h, crystallization at 130 ℃ for 96h, crystallization at 140 ℃ for 60h, crystallization at 150 ℃ for 42h and crystallization at 160 ℃ for 30h. The samples showed good hydrogenation activity before and after the poisoning of hydrogen sulfide. The crystalline form of the sample phase is detected by X-ray diffraction. Hydrogen overflow between donor phase Pt / SOD and acceptor phase HZS-5 was characterized by H2-TPD.
