A single step method was developed for biodisel production from low quality, high free fatty acid(FFA) bio oil using a heterogeneous Zn and Zr mixed oxides. Effects of metal oxide ratio, molar ratio of methanol and oil, catalyst amounts, and reaction temparature on the FAME conversion wre studied. The catalysts were evaluated for potential application in transesterificatin and esterification of palm sludge oil(PSO) with methanol to produce biodiesel. In a single step, Zn-Zr mixed metal oxide catalysts exhiited high catalytic activity(~90%) after 2h of reaction at 200℃. |
