MONITORAMENTO DA COMPOSIÇÃO EM ÉSTERES DO BIODIESEL DO ÓLEO DE AMÊNDOA DA MACAÚBA (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) EM CONTATO DIRETO COM O AÇO CARBONO E O AÇO CARBONO GALVANIZADO

The oil from the macaúba (Acrocomia aculeata) fruit, a native palm in Brazil, has a real potential for the industrial production of biodiesel. This report describes an experimental work devoted to monitor the chemical behavior of the fatty acid methyl esters from oil of the macaúba fruit kernel and the leaching of metal elements into the biodiesel put in contact with the ASTM A283 grade C and API X65 carbon steels, used to build fuel storage tanks and biodiesel pipelines. The mean values of esters contents points that the analytical precision from atomic absorption measurements was not enoug...
