SAPO-34 분자체 촉매에서 올레핀 전환반응

Conversion of Olefins over SAPO-34 Molecular Siveve Catalyst

고태석, 서곤

초록

SAPO-34 분자체 촉매에서 1-펜텐, 1-헥센, 1-헵텐, 1-옥텐 등 올레핀의 전환반응을 조사하였다. 반응온도가 낮고 탄소수가 적은 올레핀의 전환반응에서 활성저하가 심하였다. 생성물 분포로부터 올레핀 전환반응의 경로를 고찰하였다. 활성저하된 상태에서 탄소수가 적은 올레핀은 주로 중합단계를 거쳐 분해된다고 생각되나, 탄소수가 많은 올레핀은 그대로 분해된다고 보아도 생성물 분포를 설명할 수 있었다.

Olefin(1-pentene, 1-hexene, 1-heptene, 1-octene) conversions over SAPO-34 molecular sieve cata-lyst were studied. Deactivation was fast for the conversion of lower olefin at low temperature. Reaction path of olefin conversion was discussed from the product distribution. Olefin conversion was mainly proceeded through oligomerization and cracking for lower olefins over deactivated catalyst, while the product distribution of higher olefins could be explained by cracking without oligomerization.
