چکیده
Power- and biomass-to-liquid fuel processes (PBtL) can utilize renewable energy residual forestry waste to produce liquid synthetic fuels, which have the potential mitigate climate impacts of current transportation infrastructure, including long-haul aviation sector. In a previous study, we demonstrated that implementing solid oxide electrolysis cell (SOEC) in PBtL process significantly increase efficiency production, by supplying produced hydrogen reverse water gas shift (RWGS) reactor generate syngas, is then fed downstream Fischer–Tropsch (FT) reactor. The tail emitted from FT consists primarily mixture hydrogen, carbon monoxide, methane, often recycled entrained flow gasifier located at beginning process. this analysis, investigate gains as result redirecting anode an SOEC serve fuel. Supplying lower electrical work input required facilitate steam when reacting electrochemically with ions anode, turn reduce oxygen partial pressures thus alleviate material degradation. Accordingly, develop thermodynamic framework reveal performance limits fuel-assisted SOECs (FASOECs) provide strategies minimize anode. Additionally, elucidate how much match heating demands supplied cathode over broad range inlet temperatures, demonstrate influence set reaction pathways on operating FASOEC corresponding gain Based preliminary calculations, estimate production more than 90%, depending amount available system.

متن کاملInvestigation the performance of solid oxide fuel cells and the role of nanotechnology in its construction
Nanotechnology is well used in the development and performance improvement of solid oxide fuel cells (SOFCs). The high operating temperature of SOFCs (700-900 ° C) has led to serious shortcomings in their overall performance and durability. Hence, the high operating temperature has been reduced to the average temperature range of approximately 44-700 Celsius, which has improved performance and ...
