Biodiesel production from crude Jatropha Curcas oil using calcium based mixed oxide catalysts

Calcium-based, CaO–NiO (calcium nickel) and CaO–Nd2O3 (calcium neodymium) mixed oxides, were synthesized via co-precipitation process. Non-edible crude Jatropha curcus oil (JCO) was used as feedstocks for fatty acid methyl esters (FAME) synthesis in the presence of CaO–NiO and CaO–Nd2O3 mixed oxides...
