Transformation of Butanes and 1-Butene into Aromatic Hydrocarbons over Ag ion-exchanged ZSM-5 Catalyst

초록

HZSM-5와 Ag 이온으로 교환된 ZSM-5를 촉매로 사용하여 부탄과 1-부텐으로부터 방향족 화합물로의 전환반응을 수행하였다. 방향족 탄화수소의 수율은 HZSM-5 내에 Ag 이온을 도입함으로써 현저하게 증가하였다 Ag 이온들은 출발원료인 탄화수소의 탈수소 촉매로서 작용하였다. 부탄과 1-부텐의 탈수소 과정에서 생성된 수소는 Ag⁺ 이온을 Ag 금속으로 환원시킴과 동시에 산점의 형성을 유발하였다 Ag의 담지량이 다른 ZSM-5를 촉매로 사용하여 1-부텐의 전환반응을 수행하고, 이들 촉매의 산점특성 변화에 따른 효과를 검토하였다.

The transformation of butanes and 1-butene into aromatic compounds was performed over HZSM-5 catalyst and its Ag ion-exchanged ion The yield of aromatic hydrocarbons appreciably increased by incorporating silver cations into HZSM-5. The silver cations serve as catalysts for dehydrogenation of the starting hydrocarbons. Ag⁺ ions could be reduced to Ag⁰ metals with resulting in the formation of acidic OH grops by hydrogen produced during the dehydrogenation of butanes and 1-butene. The reaction of 1-butene over ZSM-5 with different loading of Ag was carried out to investigate the effect of acidic properties of these catalysts.
