Application of Synthesized CaO/MgO Catalyst on Transesterification of Jatropha Curcas Seed Oil
Keywords:clean product, high yield, low temperature, short reaction time
In looking for solution to the problems associated with the use of homogeneous catalysts, locally produced hydrated lime was mixed 50:50 with magnesium oxide to incipient, dried and calcined at 7600C for 30 minutes. Five runs of transesterification reactions were carried out using this synthesized catalyst (CaO/MgO) with jatropha curcas seed oil and methanol at 600C for five different times; 50, 60, 70, 80 and 90 minutes. The yields of 98.4, 99.0, 98.3, 98.1 and 100.0% respectively were achieved with catalyst loading of 1.5%w/w of oil and 5.5:1 methanol to oil ratio.Â The catalyst was separated out by filtration. With short reaction time and low temperature, clean biodiesel can be produced with relatively little equipment.
