Abstract

Fischer-Tropsch synthesis (FTS) converts synthesis gas (CO and $H_2$) into longer chain hydrocarbons by a surface polymerization reaction. Cobalt- or iron-based catalysts normally show excellent activity for syngas conversion to petroleum products leading to super clean diesel fuels. The catalytic activities of the catalysts in FTS depend on the number of active sites on the surface. The number of active site was determined by the active metal particle size, loading amount, reduction degree and support-active metal interaction. The investigation adopts new methodology in preparing FT catalyst, which contains the controlled synthesis of active metal. The main focus of this paper is to give an overview of the types of catalysts, also including their preparation and reduction; the types of FT reactors; and also including the reaction conditions.

피셔-트롭쉬 합성 반응은 촉매 표면에서 합성가스 (CO+$H_2$)를 탄화수소로 전환하는 반응이다. 코발트 또는 철계 촉매는 친환경적인 디젤 연료를 생산할 수 있고 합성가스의 전환율이 높은 촉매로 알려져 있다. 피셔-트롭쉬 반응에 사용되는 촉매의 활성은 촉매 표면에서의 활성점에 의존적이다. 활성점은 활성 물질의 크기, 담지량, 환원율, 지지체와 활성물질의 상호작용에 의해 결정된다. FT 촉매 제조 방법으로 활성물질의 크기를 조절하는 등의 새로운 방법들이 시도되고 있다. 여기에서는 촉매의 제조방법과 환원 특성을 비롯한 촉매의 형태와 반응 조건을 포함한 반응기 형태에 대해 알아보겠다.
