Abstract
Abstract Presence of free fatty acids in biodiesel feedstock has been source of concern to biodiesel producers hence this investigation was carried out to determine its effect on methyl esters yield by transesterification using solid base catalyst. Jatropha curcas oil of different free fatty acid compositions and methanol were transesterified with bulk calcium oxide catalyst in a stoichiometric ratio. The feedstock with 0.22 free fatty acid had 99.99 methyl ester that with 1.00 FFA had 99.11 methyl esters the one with 3.92 FFA had 94.76 methyl esters the ome with 7.8 FFA had 87.49 methyl esters and that with 8.16 FFA had 84.42 methyl esters. This indicates that methyl esters yield decrease with increase FFA of feedstocks. The presence of acid in the feedstock reduces the quantity of biodiesel produced when solid base catalyst is used.
