Abstract
Reaction characteristics and correlations between the acidic property and catalytic activity of heteropoly acid catalyst on ETBE synthesis as a gasoline octane enhancer were investigated. The amount of pyridine adsorbed on heteropoly acid catalyst and catalytic activity in the synthesis of ETBE showed a good correlation. But ammonia failed to show such a correlation because of the complex formation of ammonia adsorbed and transition metal ions. In the case of supported catalyst catalytic activity and product distribution were mainly affected by the adsorption characteristics of TBA or iso-butene.
가솔린 옥탄가 향상제인 ETBE(ethyl tert-butyl ether) 합성반응의 촉매활성과 촉매의 산특성에 상관성 및 반응특성에 관하여 연구하였다. pyridine의 흡착량과 TBA전화율은 좋은 상관성을 보였지만,
