Abstract

The study of renewable energy has become increasingly important as scientific research to overcome the increasing consumption for fossil fuel. Biodiesel production in continuous reactor system with heterogeneous catalyst has been pointed out as the solution instead of the conventional method using batch reactor. This study uses non-edible oil kapok seed oil (Ceiba pentandra) as the feedstock and MgO/CaO as catalyst. Bimetallic oxide MgO/CaO catalyst with the composition of 10 wt.% of MgO were calcined at 950ºC for 5 h. Degumming process was conducted to separate impurities from kapok seed oil. It was shown that after degumming process the oil has yellow color, brighter than before the pretreatment. It was shown that the FFA value of the feedstock was reached of 22.75%. The esterification process considerably reduced the FFA to 0.7%. The transesterification was maintained in various temperature (60-80ᵒC) in fixed bed reactor. This work was extended in various reactant flow rate of 20, 30, 40, and 50 mL/min. The highest biodiesel yield of 20.33% was achieved at 70ºC reaction temperature with feed flow rate of 20 mL/min.
