Abstract

Recent policy changes have shifted research and development to pursue technology that promotes a circular economy and net zero emissions by 2050. Current research is actively developing “drop-in” sustainable aviation fuels (SAF) that reduce emissions and are compatible with modern-day jet engines, mimicking conventional jet fuel's physical and chemical properties. While ensuring sustainable engine performance and operability using drop-in SAF is critical, several challenges remain in the economic outlook of SAF production. Biogas reforming and Fischer-Tropsch synthesis (FTS) can be used in series to convert landfill gas to SAF; however, novel design approaches must be considered to alleviate capital and operational expenses. This study analyzes the feasibility of continuous conversion of purified landfill gas to SAF via biogas reforming and FTS to determine the production and economic viability using a laboratory-scale reactor system. The system will then be assembled on a mobile trailer so that performance can be assessed onsite and case-by-case with respect to the composition of the landfill’s emissions.
