Dissertação (Mestrado em Ciência e Engenharia de Materiais) - Universidade Federal de Alfenas, Poços de Caldas, MG, 2016.https://repositorio.unifal-mg.edu.br/handle/123456789/864The purpose of this dissertation was develop supported gamma alumina catalysts for diesel oil refining. Were evaluated the effect of the type to commercial aluminum hydroxide used, the content of niobium added to the support and the peptizer agent, in the conformation. The commercial dust alumina and niobic acid were peptizated shaped by extrusion, dried and calcined in 600°C to obtain cylindrical pellets with height between 4 and 6mm and diameter between 2 and 3 mm. The Mo metal, responsable by the active phase of the catalysts, was added to the support by incipient impregnation. Were analyzed the textural properties, the mechanical resistance and the crystalline  structure of the supports. With this analysis the support with the better results was aluminum hydroxide Versal + 5% niobic acid with acetic acid 1%, and this was selected and impregnated with molibdenium. Were made the same analysis in the catalysts.application/pdfAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/CatalisadoresAluminaPetróleo - RefinaçãoMATERIAIS NAO METALICOS::CERAMICOSDissertaçãoRamos, Alfeu Saraiva
