Title (EN) BIODIESEL PURIFICATION METHOD
(FR) PROCÉDÉ DE PURIFICATION D'UN BIODIESEL
(PT) PROCESSO DE PURIFICAÇÃO DE BIODIESEL
Abstract: front page image
(EN)The present invention relates to a method for purifying biodiesel produced from castor seed oil and aimed at efficiently separating the glycerin fraction formed during transesterification of a mixture of long-chain triglycerides from castor oil in the presence of ethanol and an alkaline catalyst. The invention relates to the application of an electrostatic separation technique to castor oil biodiesel in order to separate the glycerin from the resultant stable emulsion in a relatively short time.
(FR)La présente invention concerne un procédé de purification d'un biodiesel obtenu à partir d'huile de graines de ricin, avec pour objectif de favoriser la séparation efficace de la fraction glycérine formée pendant la réaction de transestérification d'un mélange de triglycérides à chaîne longue issus de cette huile, en présence d'éthanol et d'un catalyseur alcalin. L'invention concerne l'application de la technique de séparation électrostatique au biodiesel de ricin pour séparer la glycérine de l'émulsion stable ainsi formée, de manière relativement rapide.
(PT)A presente invenção trata de um processo para purificação de biodiesel obtido a partir do όleo da semente de mamona, com o objetivo de promover a separação eficiente da fração glicerina formada durante a reação de transesterificação da uma mistura de triglicerideos de cadeia longa oriundos do όleo, em presença de etanol e catalisador alcalino. A invenção trata da aplicação da técnica de separação eletrostática ao biodiesel de mamona para separar a glicerina da emulsão estável então formada, em tempos relativamente curtos.
