Preparation of Molecular Sieve Al-SBA-15 with Two Ratios Si/Al Catalyst for Use in the Transesterification Reaction of Soybean Oil

Abstract: Molecular sieves have been applied to the triacylglycerides processing in the production of biodiesel through transesterification reaction. The purpose of obtain a material that has characteristics favorable to higher biodiesel conversion, this paper aims to synthesize molecular sieves SBA-15 and Al-SBA-15 on two reasons Si/Al (Si/Al= 10 and 100) evaluated in the transesterification reaction of soybean oil and investigate the potential of Si/Al ratios in the reaction over the acid each material. The catalysts … Show more

“…Note the presence of three well-de ned peaks in all generations, which indicates a good uniformity of materials. The presence of the rst re ection peak of the (1 0 0) plane at 2θ = 0.9° and of the (1 1 0) and (2 0 0) planes at 2θ = 1.6° and 1.8°, respectively, preserve the characteristic patterns of the SBA-15 mesostructure with re ections associated with a p6mm hexagonal symmetry of the mesoporous material [9,27,28,31,32,38,39].…”

“…A sílica mesoporosa SBA-15 é definida como peneira molecular que apresenta estrutura hexagonal altamente ordenada, possui em média elevada área superficial de 800 m²/g e estruturas que podem ser modificadas de diversas formas (10)(11)(12)(13) . A inserção de metais de transição trivalentes ou tetravalentes na superfície dos seus poros, gerando sítios ativos, aumentando sua acidez e sua estabilidade térmica e hidrotérmica promove sua aplicação como catalisador para reação de transesterificação para biocombustíveis (14) O presente trabalho se insere numa linha de pesquisa que vem sendo desenvolvida no Laboratório de Desenvolvimento de Novos Materiais -LABNOV da Unidade Acadêmica de Engenharia Química da Universidade Federal de Campina Grande, no qual, tanto a preparação de peneiras moleculares quanto a aplicação vêm sendo investigadas .…”
