“…The activation energy ( E a ) was calculated from the thermogravimetric data using the Flynn–Wall–Ozawa method. , This method is largely applied in the study of fuels, biofuels, and biomass, and it does not require the knowledge of the mechanism reaction. Since the second event did not receive any impact with the increase in heating rate, the study was conducted to the first thermal event. In this way, the E a value was obtained by linear regression between the heating rate (β) and the reciprocal temperature for the conversion degree considered in the study.…”

“…comparado a outras oleaginosas (dendê 18-20%; soja 15-17%; algodão 13-15%; moringa 20-35%), de acordo comMoreira et al (2010). Os ésteres metílicos (biodiesel) obtidos foram caracterizados de acordo com suas propriedades físico-químicas listadas na Tabela 2.Diferentemente do óleo de mamona, o éster metílico derivado desse óleo, apresentou índice de acidez (0,2802 mg KOH/g) abaixo do limite de 0,5 estabelecido pela Agência Nacional de Petróleo(ANP, 2003), e dos valores que foram encontrados porMachado et al (2006) eCosta et al (2015), indicando uma pequena quantidade de ácidos graxos livres, mostrando assim um bom estado de conservação desse biodiesel, diferente de outros óleos que apresentam grandes valores para o índice de acidez.…”
