Sustainable aviation fuels (SAFs) represent the short-term solution to reduce fossil carbon emissions from aviation. The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) was globally adopted foster make SAFs production economically competitive. Fischer-Tropsch synthetic paraffinic kerosene (FT-SPK) produced forest residue is a promising CORSIA-eligible fuel. FT conversion pathway permits integration of capture storage (CCS) technology, which provides additional offsetting capacities. FT-SPK with CCS process modelled conduct comprehensive analysis pathway. Life-cycle assessment (LCA) well-to-wake approach performed quantify SAF's footprint considering both biogenic dynamics. Results showed that 0.09 kg per dry biomass could be produced, together other hydrocarbon products. Well-to-wake scored 21.6 gCO2e MJ utilised. When dynamics, negative flux (-20.0 gCO2eMJ−1) atmosphere permanent generated. However, limited 50 %mass blend conventional Jet A/A1 Using certified reduced in 37 %, net resulted positive (30.9 gCO2eMJ−1). Sensitivity variations assumptions investigated. lifecycle fossil-emissions reported this study 49 % higher than CORSIA default value FT-SPK. In UK framework, only 0.7 fuel demand covered using national resources, but emission reduction goal targeted 2037 satisfied when CCS.

Efficient and Sustainable Biodiesel Production via Transesterification: Catalysts and Operating Conditions

Catalysts, Journal Year: 2024, Volume and Issue: 14(9), P. 581 - 581

Published: Aug. 31, 2024

Biodiesel has received tremendous attention as a sustainable energy source. This review presents an overview of various catalysts utilized in biodiesel production and compares their potential for producing biodiesel. Presented here are the excellent features while highlighting drawbacks. For instance, with homogeneous base is easy but it can only be used refined oils having low levels free fatty acid (FFAs). When esterification, causes reactor corrosion. Water FFAs do not affect heterogeneous catalysts. Thus, transesterification triglycerides into converting through esterification catalyzed more efficiently using catalyst. Biocatalysts also being to produce from high FFAs. However, biocatalysts suitable industrial application due serious mass transfer limitations. yield conversion were compared over this paper. Also presented effects different reaction parameters on The correct interplay factors like temperature, time, alcohol-to-oil molar ratio, catalyst loading produces optimal process conditions that give highest yield.
