SUGESTÕES

A reação de hidrogenação catalítica do 5-hidroximetilfurfural para a obtenção de 2,5- dimetilfurano com o uso de catalisadores suportados em óxidos mistos tem sido pouco explorada e exige uma expressiva atenção quanto aos parâmetros reacionais adotados. Consequentemente, sugere-se realizar: novas pesquisas avaliando a acidez e o efeito de outras fases ativas utilizando novos metais; análises de espectroscopia de fotoelétrons por raios X, com o intuito de obter informações sobre o estado de oxidação dos elementos na superfície do catalisador; determinação do parâmetro de Weisz Prater para comprovar a ausência de fenômenos difusionais; e a avaliação da reação nas condições de 0,5g de catalisador, concentração de HMF igual a 0,2 M, temperatura de 423K e 20 bar de pressão de H2. Também

é sugerido a proposição de algum modelo cinético para contribuir como melhor entendimento do processo de hidrogenação do HMF.
