Description
"COMPOSIÇÃO DE CATALISADOR COMPOSTO DE MISTURA DE CATALISADORES LÍQUIDOS E SÓLIDOS PARA TRANSESTERIFICAÇÃO DE ÓLEOS VEGETAIS, GORDURA ANIMAL E SUAS MISTURAS, PARA PRODUÇÃO DE ESTERES VEGETAIS ""COMPOSITION OF CATALYST COMPOSITION OF MIXTURE OF LIQUID AND SOLID CATALYZERS FOR TRANSESTERIFICATION OF VEGETABLE OILS, ANIMAL FAT AND ITS MIXTURES FOR PRODUCTION OF VEGETABLE ESTERS"
A invenção atual refere-se a um processo para a produção de uma mistura de catalisadores líquidos e sólidos baseado em alcoóxidos de metais alcalinos e alcalinos terrosos combinados nas concentrações variando em 95% em peso e 20% em peso diluido em metanol, especialmente para a obtenção de biodiesel, utilizado corno combustível em motores a diesel, que é constituído por uma ίο mistura de ésteres gerada a partir da reação de transesterificação de triglicerideos com um álcool alifático e a separação subseqüente de um subproduto de glicerina.The present invention relates to a process for producing a mixture of liquid and solid catalysts based on alkaline and alkaline earth metal alkoxides combined at concentrations ranging from 95 wt% to 20 wt% diluted in methanol, especially for The production of biodiesel, used as diesel fuel, is a mixture of esters generated from the transesterification reaction of triglycerides with an aliphatic alcohol and the subsequent separation of a glycerine byproduct.
A transesterificação, também chamada alcoólise, é a substituição da parte alcoólica de um éster, por outro álcool. A reação entre os triglicerideos e um 15 alcool alifático ocorre a temperaturas entre 20 0C e 120°C e o biodiesel gerado apresenta um excelente desempenho no motor, similar ao diesel mineral. É o principal método utilizado para obtenção de biodiesel, empregado na redução da viscosidade de óleos vegetais e atende às exigências feitas pela ASTM (American Society for Testing and Materiais) como biodiesel. Na 20 transesterificação, os triglicerideos encontrados na gordura animal e óleos vegetais (por exemplo, óleo de soja, amendoim, palma, girassol e algodão, pinhão manso,dendê, entre outros ) ou a combinação deles em quaisquer porcentagens reagem com um álcool de cadeia C1 a C5 (por exemplo, metanol, etanol.etc.) formando ésteres e glicerol e eventualmente matéria graxa.Transesterification, also called alcohololysis, is the replacement of the alcoholic part of an ester with another alcohol. The reaction between triglycerides and an aliphatic alcohol occurs at temperatures between 20 ° C and 120 ° C and the generated biodiesel has excellent engine performance, similar to mineral diesel. It is the main method used to obtain biodiesel, used to reduce the viscosity of vegetable oils and meets the requirements made by the American Society for Testing and Materials (ASTM) as biodiesel. In transesterification, triglycerides found in animal fat and vegetable oils (eg soybean, peanut, palm, sunflower and cotton, jatropha, palm oil, among others) or their combination in any percentages react with a chain alcohol C1 to C5 (e.g. methanol, ethanol, etc.) forming esters and glycerol and optionally grease.
A reação de transesterificação para a produção de biodiesel é executada normalmente utilizando bases de metais alcalinos e/ou alcalinos terrosos como por exemplo, NaOH, NaOCH3, e catalisadores orgâno metálicos tais como NaCH3.The transesterification reaction for biodiesel production is normally performed using alkaline and / or alkaline earth metal bases such as NaOH, NaOCH3, and metal organic catalysts such as NaCH3.
Devido ao elevado custo das matérias primas, o custo do biodiesel é maior que o do diesel mineral, sendo importante reduzir os custos de produção, aprimorando os processos com novos catalisadores para redução do preço final do biodiesel.Due to the high cost of raw materials, the cost of biodiesel is higher than that of mineral diesel, and it is important to reduce production costs by improving processes with new catalysts to reduce the final price of biodiesel.
Uma das maneiras para reduzir os custos é melhorar a taxa de conversão dos óleos vegetais, gordura animal e suas misturas em ésteres, reduzindo as perdas no processo produtivo. Um exemplo desta tentativa para utilizar catalisadores menos dispendiosos é apresentada na WO 2006/134845 que descreve o uso de catalisadores com base sólida para a produção do combustível de biodiesel. A ío referência apresenta ainda o uso do material CaO como um catalisador de transesterificação. Este catalisador porém gera problemas de fluxo de processo, pois expande durante a reação de transesterificação, impedindo um fluxo continuo da produção do biodiesel, além disso a expansão do catalisador dificulta a separação das fases ésteres e glicerina.One of the ways to reduce costs is to improve the conversion rate of vegetable oils, animal fat and their mixtures into esters, reducing losses in the production process. An example of this attempt to use less expensive catalysts is given in WO 2006/134845 which describes the use of solid based catalysts for the production of biodiesel fuel. Reference also discloses the use of CaO material as a transesterification catalyst. This catalyst however generates process flow problems as it expands during the transesterification reaction, preventing a continuous flow of biodiesel production, furthermore catalyst expansion makes it difficult to separate the ester and glycerin phases.

Os catalisadores mais freqüentemente usados são alcalinos e homogêneos, usados separadamente, como descrito nos documentos US 2,271,619, US 2,360,844, US 2,383,579, US 2,383,680, US 2,383,581, US 2,383,614, US 2,383,601, US 2,383,632, US 2,383,633, e US 5,730,029 que descrevem o uso 20 de metóxido de sódio como catalisador alcalino na transesterificação de óleos vegetais com um álcool de cadeia C1 a C5 (por exemplo, metanol, etanol,etc.), além de outros catalisadores como hidróxidos de sódio e carbonatos de metais alcalinos terrosos que também são citados. No Brasil um processo de transesterificação foi descrito em 1980 (primeiro processo apresentando uma 25 transesterificação) através do documento P18007957 e utiliza separadamente hidróxido de sódio ou potássio como catalisador da transesterificação, gerando como produto ésteres para uso como combustível.
