Optimization processes of biodiesel production from pig and neem (Azadirachta indica a.Juss) seeds blend oil using alternative catalysts from waste biomass

摘要

This study tested the suitability of solid residue (CaO) derived from the mixture of wastes biomass as based catalyst transesterification conversion of the blend of neem oilseed (Azadirachta indica A.Juss) with rendered pig fat. Blending was done in the ratio of Neem oil: Pig fat oil (v/v) as 10:90 (NO10),20:80 (NO20),30:70 (NO30), 40:60 (NO40), 50:50 (NO50), 60:40 (NO60), 70:30 (NO70), 80:20 (NO80), and 90:10 (NO90), respectively. Process parameter transesterification optimization of methanolysis CaO catalyst for synthesis of 60:40 to mixed oil biodiesel (MOB) was investigated using central composite design that generates thirty experimental runs and were carried out.
