Abstract

In bio-jet fuel production, selecting operating conditions of hydro-upgrading is of great importance to make iso-Paraffin rich hydrocarbons with carbon distribution including jet fuel range. Herein, iso-Paraffin rich biofuel including jet fuel range hydrocarbons ($C_8-C_{16}$) is produced from simultaneous cracking and isomerization using n-Paraffin rich hydrocarbon derived from hydrotreated vegetable oil over 0.5 wt..% Pt/Zeolite catalyst. We report and analyze the yields and compositions in the produced hydrocarbons affected by various operating conditions, such as reaction temperature, reaction pressure, molar ratio of reactants, and weight hourly space velocity. Aforementioned operating conditions not only can help interpret the reaction dynamics of hydro-upgrading, but also further produce bio jet-fuel after distillation.

바이오항공유 제조 공정 내 수첨업그레이딩 공정의 운전조건 선정은 반응물로부터 얻고자 하는 주생성물인 탄화수소 화합물에 대하여 바이오항공유로서 원하는 탄소수 분포의 물성을 갖도록 하기위한 중요한 인자이다. 본 연구에서는 식물성 오일 유래 노말 파라핀계 탄화수소 화합물에 대한 수첨 업그레이딩 반응이 0.5 wt.% Pt/Zeolite 촉매 하에서 수행되었으며, 이를 통해 크래킹 반응과 이성질화 반응이 동반됨으로써 바이오항공유로서 물성을 갖는 탄소수 분포인 $C_8-C_{16}$에 해당하는 노말 파라핀계와 이소 파라핀계가 혼합된 탄화수소류 화합물이 제조되었다. 반응온도, 반응압력, 반응물 몰비와 공간속도를 변화하여 얻어진 생성물의 수율 및 조성을 분석하였다. 상기 공정 조건에 대한 정보는 수첨 업그레이딩 반응특성의 이해뿐 아니라 향후 증류를 통한 바이오항공유 제조에 도움을 줄 수 있다.
