Abstract
불순물로서 에탄올 함유하는 에틸렌 스트림 또는 불순물로서 프로판을 함유하는 프로필렌 스트림을, 에틸렌 또는 프로필렌을 선별적으로 흡착하는 흡착제 베드에서 50 내지 200℃온도하에 흡착 공정에 적용시켜 실질적으로 모든 에틸렌 또는 프로필렌을 흡착시킨다. 그 다음 정제된 에틸렌 또는 프로필렌 스트림은 산소 및 임의의 암모니아의 존재하에 부분 산화반응에 적용시켜 다양한 부분 산화반응 생성물을 형성한다. 이 공정은 반응하지 않은 에틸렌 또는 프로필렌을 재순환시키면서 낮은 관통 전환율로 작동한다. 본 발명의 시스템에서 흡착 유니트는 부분적 산화 반응기의 상류 또는 하류에 존재할 수 있다.
