Abstract: In this study, the olive cake was successfully developed and applied as a substrate to produce a lignin-based catalyst for biodiesel production. Three lignin-based solid acid catalysts were prepared from the incomplete carbonized alkali lignin using concentrated sulfuric acid. The catalyst underwent a detailed characterization analysis in terms of its functional groups of active sites, surface area, acid sites density and morphological structure. For the catalytic activity test, prepared catalysts were studied for their ability to catalyze both esterification and transesterification reactions of waste vegetable oil (WVO) ≈2 FFA (% w/w).
