Abstract
본 발명은 메타크실렌과 적어도 하나의 다른 C8방향족 탄화수소로 이루어진 혼합물을 흡착 조건에서 나트륨 이온을 함유하는 Y제올라이트로 이루어진 흡착제와 접촉시켜서 상기 흡착제 상에 메타크실렌을 선택적으로 흡착하고, 상기 혼합물의 비흡착된 부분은 상기 흡착제와의 접촉에서 제거하고 메타크실렌은 탈착 조건에서 탈착제로 탈착시켜 회수하며, 여기서 흡착 조건은 100 내지 150℃의 온도를 포함하며, 흡착제는 500℃에서 1.5 내지 3.0중량% LOI의 수화정도를 갖는 것을 특징으로 하는, 상기 혼합물에서 메타크실렌을 분리하기 위한 방법에 관한것이다.The present invention selectively adsorbs metha xylene on the adsorbent by contacting a mixture consisting of metha xylene with at least one other C 8 aromatic hydrocarbon with an adsorbent consisting of Y zeolite containing sodium ions under adsorption conditions, wherein The adsorbed portion is removed from contact with the adsorbent and the metha xylene is recovered by desorption with desorbent under desorption conditions, wherein the adsorbent conditions include a temperature of 100 to 150 ° C., and the adsorbent is 1.5 to 3.0 wt% LOI at 500 ° C. It relates to a method for separating metha xylene from the mixture, characterized in that having a degree of hydration of.
