Biodiesel Manufacturing from Kesambi Seed

Biodiesel is an ester alkyl that can be used for diesel as substitute for diesel engine. Biodiesel was made.from biofuel oil either vegetation or animal oil. Kesambi oil (Schleichera oleosa L) was strongly presumed can be used as raw material for biodiesel due to its fatry acid compositions are almost the same with other biofuel oils. Production process for biodiesel manufacture normally use estrans or esterification-transesterification process.This study examined the effect of some treatments on the characteristics of biodiesel qualty.The measured variable factors were : process stage, methanol concentration,and duration time of esterification process. Data analysis was accomplished through randomized complete design with factorial trial.The treatments of process stages were ET (Esterification-transesterification), EET (Esterification-esterification transesterification), ENT (Esteriftcation-netralizati-on transesterification) and BIN (Esterification transesterification-netralization)M.ethanolconcentrations were 15:1 and 20:1(ratioof methanol molar to oil used). Esterification times were 30 and 60 minutes. Qualilly analyses were consideredon the basis of acid number, moisture, yield,viscosily and densily. The results showed rangevalueof moisture content0.10- 0.82%,acid number 0.625 - 1.330 mgKOH/g oil, kinematic- viscosily 12.70 - 16.40 cSt, densi!J 0.906 - 0.920 g/ cm',biodieseyl ield after degumming 63.01 - 96.9 3%. The ENT procedureis concludedas the best method compared with the others.
