Optimum Lignin Oil - Finding the most suitable feedstock to replace cycloalkanes in Sustainable Aviation Fuel (SAF).

This study highlights the effectiveness of hydrodeoxygenation (HDO) in converting lignin oils from Eucalyptus, Poplar, and Pine wood, derived from reductive catalytic fractionation (RCF), into renewable cycloalkanes for jet fuel. Using a low-cost Ni2P/SiO2 catalyst, the process achieved yields of 91 %, 83 %, and 75 % of renewable cycloalkanes respectively. In addition, the process exhibited high selectivity towards a specific range of hydrocarbons mostly present in aviation fuel (C9 to C15), with values of 70%, 60% and 62% for the three feedstocks, respectively, showcasing the potential for high-value fuel production.
