Process analysis and comparative assessment of advanced thermochemical pathways for e-kerosene production

Climate change and energy supply are major driving forces for the promotion of sustainable fuels production. In aviation sector, due to inherent difficulties adopt electrification methods long distance flights, successful implementation fuel (SAF) is crucial achievement greenhouse gas emissions mitigation strategies. This study presents four different pathways valorization captured CO2 into synthetic kerosene using renewable hydrogen demonstrates comparative assessment in terms various technical aspects such as consumption, thermal energetic efficiency produced e-kerosene quality. Two based on production Low Temperature Fischer-Tropsch synthesis CO (LTFT) or conversion fuels, while other two upgrading light alcohols (methanol ethanol) derived from hydrogenation. The process models were developed Aspen Plus. Simulation results revealed that LTFT pathway most efficient maximize jet yield with lower exergy losses. Indicatively case, 90.7% initial carbon utilized fraction synthesis, overall reaches up 70.9% whereas plant exergetic 72.6%. basic properties at all cases meet required Jet-A1 specifications close them.
