ANALISIS ENERGY PRODUKSI BIODIESEL DENGAN METODE METANOL SUPER KRITIS
ABSTRACT: Supercritical
methanol process has several advantages, that is not influenced by the material
conditions for the free fatty acids contained in the materials will be
esterified into methyl esters directly, the conversion rate of oil into methyl
ester of tall, shorter process time and not influenced by the presence of
water. However, this method has a weakness that is the need safety treatment
because the process involves high temperatures and pressures. Super critical
methanol method has a 2-stage hydrolysis process which took place on the state
of the sub critical water to separate the free fatty acid (FFA) and glycerol,
methanolyisis place on super critical conditions of methanol with the aim of
changing the FFA to biodiesel, both processes take place at a temperature of
270 ° C and pressure of 70-20 MPa.. From the research of biodiesel production
process using supercritical methanol without catalyst, the reaction time is
faster total reaction time of 9250 seconds (2.57 hours), with the result of
more production (400 ml biodiesel) from the raw material 5% water (35 ml ),
cooking oil 95% (665 ml), and 95% wt methanol (200 ml), has a 52.39% energy
efficiency.
