In order to reduce the effects of greenhouse gas (GHG) emissions, the South Korean government has announced a special platform of technologies as part of an effort to minimize global climate change. To further this effort, the Korean government has pledged to increase low-carbon and carbon neutral resources for biofuel derived from biomass to replace fossil and to decrease levels of carbon dioxide. In general, second generation biofuel produced form woody biomass is expected to be an effective avenue for reducing fossil fuel consumption and greenhouse gas (GHG) emissions in road transport. It is important that under the new Korean initiative, pilot scale studies evolve practices to produce biomass-to-liquid (BTL) fuel. This study reports the quality characteristics of F-T diesel for production of BTL fuel. F-T(Fischer-Tropsch) diesel fuel can be used in conventional diesel engines, pure or blended with conventional diesel, due to its similar physical properties to diesel. F-T diesel after distillation has a very high cetane number(74), low aromatic composition and sulfur free level(0.7 ppm).

Biomas-To-Liqufied(BTL) can be used for conventional diesel engines, pure or blended with conventional diesel due to its similar physical properties to diesel. BTL fuel was first produced by Fischer-Trosch(F-T) process with syngas(H2/CO), Fe based catalyst in low temperature condition(240 ℃) in Korea. This study was focused on fuel quality and emission characteristics of BTL diesel to use transport fuel in Korea.

전 세계적으로 폐플라스틱 발생에 따른 환경적 문제로 인해 이를 처리하기 위한 다양한 연구가 진행되고 있다. 이 중 폐플라스틱을 열분해하여 연료 및 원료 등으로 재활용하는 방법이 보편적이다. 본 연구에서는 '폐플라스틱 열분해유(WPPO)의 나프타 원료로 활용'을 목적으로 총 5종의 폐플라스틱 열분해유(WPPO)의 물성분석을 통해 나프타 원료로 사용이 가능한지 살펴봄과 동시에 넓은 비점범위로 인해 분리정제 기술 중 하나인 감압증류를 통해 light fraction과 heavy fraction으로 분획 및 GC-VUV로 paraffin, 올레핀 함량 및 기타 화합물 등의 구성성분을 나타내었다. 그 결과, WPPO의 원료, 분획에 상관없이 높은 올레핀 함량이 나타났고 방향족 및 paraffin 함량 등은 원료에 따라 차이가 발생하였고 산소 및 기타 화합물도 원료 및 분획별 차이가 큰 것으로 나타났다. 또한, light fraction은 나프타와 유사한 탄소분포를 나타내지만, heavy fraction은 탄소분포가 C<sub>11</sub> ~ C<sub>14</sub>로 나타났다. 결론적으로, 폐플라스틱 열분해유의 나프타원료 활용을 위해서 추가 공정이나 원료 선별 등이 필요할 것으로 판단된다. Globally, the amount of waste plastics has been occurring to environmental problems. As a result, it is necessary to research methods that utilize waste plastic pyrolysis oil (WPPO) produced by pyrolysis. One such method being studied is utilizing WPPO as a naphtha feedstock. In this study, five types of WPPO were analyzed to determine whether they can be used as raw materials for naphtha. Because of their wide boiling point range, the WPPOs were fractionated into light and heavy fractions through vacuum distillation, and the separation and purification techniques were analyzed using GC-VUV to determine the content of paraffin, olefin, and other compounds. All WPPOs showed high olefin content regardless of the source and fraction. Aromatic and paraffin content varied depending on the source, and oxygen and other compounds also varied significantly by source and fraction. In addition, the light fraction showed a carbon distribution similar to that of naphtha, whereas the heavy fraction showed a carbon distribution of C<sub>11</sub> ~ C<sub>14</sub>. In conclusion, additional processes and raw material selection are required to utilize waste plastic pyrolysis oil as a raw material for naphtha.
