Abstract:
A transesterification catalyst that is heterogeneous and a method for preparing said transesterification catalyst are provided. The catalyst can be used in a variety of transesterification reactor configurations including CSTR (continuous stirred tank reactors), ebullated (or ebullating) beds or any other fluidized bed reactors, and PFR (plug flow, fixed bed reactors). The catalyst can be used for manufacturing commercial grade biodiesel, biolubricants and glycerin.
Abstract:
Bei einem Verfahren zur Reinigung von Fettsäurealkylestern, inbesondere Methyl- und Ethylestern, mittels Vakuumdestillation in einer Destillationskolonne, wird in die Destillationskolonne Wasser oder Wasserdampf eingebracht und bei der Destillation mit den Fettsäurealkylestern in der Gasphase kontaktiert. Hierdurch wird eine signifikante Reduktion des Schwefelgehalts sowie der Säurezahl des Fettsäurealkylesters erzielt.

Abstract:
The present invention relates to a process for the conversion of a feedstock containing one or more fatty acid triglycerides to a mixture containing one or more fatty acid alkyl esters and t-alkyl glycerols, comprising reacting said feedstock with a compound of formula (I): R-O-R I (I) wherein: R I is an alkyl, alkenyl or alkynyl having 1-18 carbon atoms; R is H or a tertiary alkyl group, wherein said reaction takes place in the presence of an acid transesterification catalyst by irradiation with microwaves and/or ultrasound and/or radio waves.
Abstract:
A presente invenção trata de um processo para separação e/ou purificação do Biodiesel usando dióxido de carbono pressurizado. Pode ser aplicada em qualquer processo de produção de biodiosel usando qualquer fonte de matéria prima. O processo consiste em injetar CO2 10 a 50% de CO2 no sistema após a reação e aumentar a pressão do sistema numa faixa de 5 a 20 Mpa na temperatura ambiente. Duas fases se formam sendo a fase superior rica em biodiesel e álcool e a fase inferior formada por álcool, monoacilglicerol diacilglicerol, óleo não reagido, sais e glicerina. A remoção das fases pode ser feito por meio de um vaso de pressão equipado uma válvula de sentido único
Abstract:
Refere-se a presente invenção à preparação de compostos de ésteres de ácidos carboxílicos, biodiesel (B) a partir de mieroalgas, para a utilização como biocombustível em ignição por compressão. O objetivo é alcançado por meio de um processo de hidroesterificação de biomassa úmida de mieroalgas (MU), o qual compreende uma etapa de hidrólise e uma etapa de esterificação por catálise heterogénea. A biomassa úmida de mieroalgas (MU) é resultante de um processo de concentração de cultivo e é hidrolisada diretamente em uma coluna de hidrólise (20). Após a hidrólise são obtidos ácidos graxos (C), água (A) e glicerina bruta (G). Os ácidos graxos (C) são esterificados por destilação reativa em presença de um catalisador heterogéneo impregnado (I).
Abstract:
The present invention relates to a method for producing biodiesel comprising a step of generating fatty acid alkyl ester and glycerol by a transesterification of animal and vegetable oils and fats and fatty acid alcohols in the presence of porous materials. The method is characterized by a high response speed and high FAME conversion, and can be performed in a consecutive process. Further, according to the method, a high-purity fatty acid alkyl ester and glycol can be produced irrespective of the content of free fatty acids (FFAs). Further, since the method does not use a catalyst, the total processing time and cost can be reduced, and the method is environmentally friendly.
Abstract:
Methods and systems for the production and isolation of fatty acid methyl esters (FAMEs) from a lipid source are described. The method includes extracting a lipid from a lipid source and transesterifying the lipid into a FAME. The method may also include fractionating the FAME from the system. A method of selectively transesterifying a lipid into a FAME is also described.
