Summary: Catalytic-free parallel-plate-type dielectric barrier discharge (DBD) plasma was used to hydrogenate palm oil using glycerol as a hydrogen donor, resulting in enhanced oxidation stability of hydrogenated fatty acid methyl ester (H-FAME). Optimal reaction conditions were determined, and it was found that plasma effectively extracted hydrogen radicals from glycerol and reacted with C-C bonds. The hydrogenated palm oil was then converted into HFAME via base-catalyzed transesterification. The developed plasma hydrogenation process adds value to waste glycerol and provides alternative hydrogen sources, while also being environmentally friendly.
