Resumo: | Fatty acid esters (Biodiesel) are commonly produced by homogeneous basic catalytic transesterification reaction, whose sensitivity to the presence of water and free fatty acids (FFAs) in the raw material is one of the main drawbacks. The search for production processes that allow the use of vegetable oils with less added value is of interest to the biofuel industry. A promising alternative is hydroesterification, whose first stage is the hydrolysis of triacylglycerols, producing FFAs and glycerol products. Therefore, instead of decreasing acidity of the raw material through refining, the hydrolysis stage purposely increases its acidity. Then, glycerol is removed and the FFAs are subjected to an esterification reaction to produce fatty acid esters and water as a by-product. Therefore, this work presents a literature review, which has as main focus the production of biodiesel from hydroesterification. Alternative raw materials with potential in the current market are also presented. It was possible to verify that hydroesterification offers advantages when compared to conventional reactions. When carried out under conditions of high temperature and pressure, it can reduce the difficulties associated with the use of catalysts, becoming a promising alternative to be used as a method of biodiesel production. |

A busca por processos de produção que permitem o uso de óleos vegetais com menor valor agregado é de interesse da indústria do biocombustível. Uma alternativa promissora é a hidroesterificação, cuja primeira etapa é a hidrólise de triacilgliceróis produzindo AGLs e glicerol, portanto, ao invés de diminuir a acidez da matéria-prima por meio do refino, a etapa de hidrólise aumenta propositalmente a sua acidez. Em seguida, o glicerol é removido e os AGLs são submetidos à reação de esterificação para produção dos ésteres de ácidos graxos e água como subproduto. Diante disso, neste trabalho é apresentada a revisão da literatura, com enfoque principal na produção de biodiesel a partir da hidroesterificação, bem como as matérias‑primas alternativas com potencial no mercado atual. Foi possível constatar que a hidroesterificação apresenta diversas vantagens em relação à reação convencional. Se realizada em condições de alta temperatura e pressão, pode reduzir as dificuldades associadas ao uso de catalisadores, tornando-se uma alternativa promissora a ser empregada como método de produção do biodiesel.Editora Uningá2020-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revista.uninga.br/uningareviews/article/view/3522Uningá Review ; Vol. 35 (2020); eRUR3522Uningá Review ; v. 35 (2020); eRUR35222178-2571reponame:UNINGÁ Reviewinstname:Centro Universitário Uningáinstacron:UNINGAporhttps://revista.uninga.br/uningareviews/article/view/3522/2214Copyright (c) 2020 REVISTA UNINGÁ REVIEWinfo:eu-repo/semantics/openAccessde Mello, Bruna Tais FerreiraFilho, Lúcio Cardosoda Silva, Camila2023-10-17T15:05:53Zoai:ojs.revista.uninga.br:article/3522Revistahttps://revista.uninga.br/uningareviews/indexPUBhttps://revista.uninga.br/uningareviews/oairevistauningareview@uninga.edu.br || sec.revistas@uninga.edu.br2178-25712178-2571opendoar:2023-10-17T15:05:53UNINGÁ Review - Centro Universitário Uningáfalse |
