(632c) Efficient Deoxygenation of Sludge Vegetable Oil over Bimetallic Doped Activated Carbon Catalyst for the Production of Green-Diesel-like Fuel

Deoxygenation (DOx) of waste sludge palm oil (WSPO) into green fuel using activated carbon-based catalyst supported with tungsten and lanthanum oxides (La-W/AC) is reported in this study. La-W/AC catalyst was synthesized via co-precipitation (CP) of tungsten and lanthanum onto the activated carbon. La-W/AC catalyst was characterized using various characterization techniques and the results showed high surface area and acidity. Furthermore, the effect of catalyst loading, reaction time, and reaction temperature on deoxygenation of WSPO were investigated. The catalyst demonstrated a superior catalytic performance in deoxygenation reaction under optimal reaction conditions (0.5% catalyst loading, 1 hour and 250 ^oC reaction temperature), recording 98% conversion of WSPO to green fuel. Reusability test of the catalyst was performed and the results showed that the synthesized catalyst can be reused up to 8 times maintaining green fuel conversion of more than 87%. The catalytic activity of the catalyst was attributed by the presence of the acid and basic sites on the synthesized catalyst. The TOFs of the waste sludge palm oil was also determined in this work.
