An investigation on process
intensification on biodiesel production was carried with Jatropha curcas seed
oil, methanol and five solid base catalysts in a process intensified pilot
plant. This Process Intensify Pilot Plant had not the following unit operations
as in conventional plants; Neutralizer, Washer, Dryer, Heat exchanger and
Condenser to reduce production cost. Five samples of biodiesel were produced
with 3 moles of methanol to 1 mole of oil and 1.5 % catalyst loading (w/w of
oil). Methyl ester yields of 97.4, 96.94, 95.76, 99.99 and 98.25 % catalyzed by
bulk calcium oxide (CaO), super base calcium oxide (CaO/(NH4)2CO3), bulk
magnesium oxide (MgO), calcium oxide/magnesium oxide (CaO/MgO) and 10 %
impregnated potassium on calcium oxide/magnesium oxide (K-CaO/MgO) were
obtained respectively. The products were analyzed in accordance with ASTM, EN
and ISO standards for biodiesel and were found satisfactory for use in
compression ignition engines. All the biodiesel samples were found not to be
easily oxidized as they did not have poly-unsaturated esters such as: linoleate
(18:2) and linoleneate (18:3). It was found that this process produced clean
biodiesel devoid of glycerol. Also one of the findings from this study is
transesterification does not support reversibility.
