To reduce the GHG impacts from aviation fuel, biojet fuels are being researched and manufactured through various processes. However biomass-derived jet fuels should meet severer quality requirements than petroleum based jet fuel to secure the safety. In case of HEFA processed biojetfuel has a possibility that FAMEs are produced through de-oxydation process. Accoring to HEFA biojet fuel’s specification, FAME contents should be controled less thane 5mg/kg to keep oxidation stability or to prevent clogging problems at low temperature. In this study, FAME stds were diluted with 0, 2, 5, 10mg/kg of overall concentration in petro-based jet fuel. By using GCxGC TOF-MS, the resolution of FAMEs is enhanced comparing with previous methods such as GC-MS(IP 585) and HPLC(IP 590). Calibration of each components and expression of results will conduct for the future research. |
