SINTESIS BIODIESEL DENGAN KATALIS HETEROGEN LEMPUNG CENGAR YANG DIAKTIVASI DENGAN NaOH: PENGARUH WAKTU REAKSI DAN RASIO MOLAR MINYAK: METANOL
Abstract: Biodiesel is mainly
produced from vegetable oils or animal fats by themethod of transesterification
reaction using catalyst. Manyheterogenous solid acid and base catalyst have
been studied for thetransesterification of various vegetables oils. In this
study thetransesterification of vegetable oil to fatty acid methyl esters
wasstudied using sodium hidroxide activated clay catalyst. The catalystwas
prepared by activating clay with NaOH by impregnation method.50 ml NaOH
solution was gradually added to 50 g clays, stirred,owashed and calcined at 300
C for 3 hours. The transesterificationreaction was performed by using of
optimum NaOH loading catalyst,reaction time was variated for 4 to 10 hour,
molar ratio of oil/metanolofrom 1:3, 1:6, 1:9 and 1:12 at 60 C. It was found
that the maximalproduction of biodiesel which is 78.285% on catalyst that have
20%(w/w) loading NaOH, reaction time for 8 hours, oil-methanol molaroratio is
1:6, and the temperature reaction at 60oC.
