  Abstract

고령토를 사용하여 합성한 faujasite형 zeolite를 Zn2+, La3+, H+(NH4+)로 양이온 교환하고 Na-, Zn-, La- 및 H-faujasite의 1-butene의 분해 및 이성화반응에 대한 촉매활성을 조사하였다. 1-Butene→2-butene 반응은 강한 산점이 별로 없는 zeolite에서도 쉽게 일어난다. Isobutene생성에 대한 활성은 La > H > Zn > Na-faujasite의 순으로 La-faujasite가 가장 컸다. Propylene 생성에 대한 활성도 같은 경향을 나타냈으나 여기서는 La-와 H-faujasite의 활성이 거의 같은 정도이었다. 본 실험결과를 보면 zeolite의 산성도(산의 강도 및 량)는 1-butene의 분해 및 이성화 반응에 대한 활성과 직접적인 관계가 있는 것 같다. Faujasite type zeolite synthesized from kaolin minerals was cation-exchanged and the catalytic activities of Na-, Zn-, La-, and hydrogen-faujasites for 1-butene cracking and isomerization were studied. 1-Butene→2-butene took place readily even on zeolites having no strong acid sites. The order of activity for isobutene formation was La > H > Zn > Na-faujasite, La-faujasite showing much higher activity. The same trend was observed for propylene formation except that both La-and H-faujasite showed comparable activity. The results seem to indicate that the activities for 1-buten cracking and isomerization on zeolite are directly related to the strength and concentration of the acid sites on zeolites.
