A fim de preparar diferentes catalisadores a base do mesmo material uma al?quota foi previamente aquecida a 400? C e outra a 700? C, as quais foram denominadas S400 e S700 que ap?s tratamento com H2SO4, deram origem a dois diferentes catalisadores, chamados de C400 e C700. Os catalisadores apresentaram volume total dos mesoporos de 0,23 cm3/g (C400) e 0,20 cm3/g (C700) e ?rea superficial de 31,06 m2/g (C400) e 23,10 m2/g (C700). Pela primeira vez foi utilizado ?cido de Bronsted imobilizado em s?lica para a convers?o de OGR em biodiesel. Ambos C400 e C700 apresentaram alta atividade na convers?o do ?leo e gordura residuais altamente ?cidos (13,7 mg de KOH) e com teor de ?gua de 0,58%, a biodiesel (?steres met?licos de ?cido graxo) em aproximadamente 99,4 %. As rea??es foram repetidas 4 vezes antes do catalisador perder sua atividade catal?tica.Submitted by Jos?

In order to prepare different catalysts the basis of the same material aliquot was preheated to 400? C and another at 700? C, which were referred to as S400 and S700 which upon treatment with H2SO4, gave rise to two different catalysts, called C400 and C700. The catalysts showed total volume of mesopores of 0.23 cm3/g (C400) and 0.20 cm3/g (C700) and surface area of 31.06 m2/g (C400) and 23.10 m2/g (C700). For the first time was used Bronsted acid immobilized on silica OGR for conversion into biodiesel. Both C400 and C700 showed high activity in the oil conversion and highly acidic waste fat (13.7 mg of KOH) and 0.58% water content, biodiesel (fatty acid methyl esters) by approximately 99.4% . Reactions were repeated four times before the catalyst to lose its catalytic activity.porUFVJMA concess?o da licen?a deste item refere-se ao ? termo de autoriza??o impresso assinado pelo autor, assim como na licen?a Creative Commons, com as seguintes condi??es: Na qualidade de titular dos direitos de autor da publica??o, autorizo a Universidade Federal dos Vales do Jequitinhonha e Mucuri e o IBICT a disponibilizar por meio de seus reposit?rios, sem ressarcimento dos direitos autorais, de acordo com a Lei n? 9610/98, o texto integral da obra disponibilizada, conforme permiss?es assinaladas, para fins de leitura, impress?o e/ou download, a t?tulo de divulga??o da produ??o cient?fica brasileira, e preserva??o, a partir desta data.info:eu-repo/semantics/openAccessAplica??o de catalisadores a base de SiO2-SO3H na s?ntese de biodiesel: estudo cin?tico do processo de transesterifica??o de triacilglicerideosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisS?lica gel amorfaS?lica sulfonadaCatalisadores heterog?neos ?cidosTransesterifica??oEstudo cin?tico?leos e gorduras residuaisAmorphous silica gelSilica sulfonatedHeterogeneous acid catalystsTransesterificationKinetic studyResidual oil and fatreponame:Repositório Institucional da UFVJMinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMTEXTgelson_cerqueira_oliveira_junior.pdf.txtgelson_cerqueira_oliveira_junior.pdf.txtExtracted texttext/plain156784http://acervo.ufvjm.edu.br/jspui/bitstream/1/1444/6/gelson_cerqueira_oliveira_junior.pdf.txt1d417d64458f61c1cfe9e24e60a7cd6bMD56LICENSElicense.txtlicense.txttext/plain;
