Abstract

GTL (gas-to-liquid) fuel produced by the Fischer-Tropsch reaction of carbon monoxide (CO) and hydrogen ($H_2$) is expected to be one of the environmental friendly biomass based alternatives and blended to petrodiesel. In this study, the characteristic of the fuel was analyzed by its concentration differences after blending petrodiesel in domestic market with different amounts of GTL fuel which produced from Shell. Gas chromatography shows that GTL fuel consists of longer paraffin chain than common diesel. GTL fuel showed a high flash point, distillation, kinematic viscosity, and derived cetane number. In addition, GTL fuel showed lower lubricity due to low sulfur content.

일산화탄소(CO)와 수소($H_2$)로부터 Fischer-Tropsch반응을 통해 합성된 GTL (gas-to-liquid)연료는 친환경적인 연료로 기존의 석유디젤을 대체, 또는 혼합하여 사용될 수 있는 연료로 크게 관심을 받고 있다. 본 논문에서는 Shell사에서 생산된 GTL연료와 국내유통중인 석유디젤을 일정 비율로 혼합하여 농도 별 연료특성을 분석하였다. 가스크로마토그래피를 이용해 GTL이 일반디젤보다 긴 파라핀계 화합물로 구성되어져 있음을 확인하였으며, 높은 인화점, 증류성상, 동점도, 유도세탄가와 함께, 낮은 황분으로 인한 윤활성감소를 보여주었다.
