Abstract

The transformation of alkylaromatic hydrocarbons using zeolite catalysts play big part in the current petrochemical industry. Here we review recent advances in the understanding of the reaction mechanisms of various alkylaromatic conversions with respect to the structural and physicochemical properties of zeolite catalysts employed. Indeed, the shape-selective nature of zeolite catalysts determines the type of reaction intermediates and hence the prevailing reaction mechanism together with the product distribution. The prospect of zeolite catalysis in the developement of more efficient petrochemical processes is also described.

제올라이트 촉매를 이용한 알킬 방향족 화합물의 전환은 현대 석유화학 산업에서 큰 비중을 차지한다. 본 총설에서는 제올라이트의 구조적 물리화학적 특성에 따른 알킬 방향족 화합물 전환 반응의 기구에 대해 고찰하였다. 제올라이트의 형상선택성은 알킬 방향족 화합물 전환에 있어서 반응중간체의 생성을 조절함으로써 반응 기구 및 생성물 분포에 직접적인 영향을 미친다. 다양한 알킬 방향족 화합물의 전환 반응에 대하여 반응 중간체의 구조 및 역할에 대한 고찰을 통해 지금까지 알려진 반응기구들을 정리하였다. 아울러 제올라이트 촉매를 기초로 하는 향후 석유화학 공정 개발에 대한 전망을 기술하였다.
