Adsorção De Contaminantes Do Biodiesel Por Fibras De Bagaço Modificadas Na Superfície

Abstract: Recebido em 25/05/2017; aceito em 24/10/2017; publicado na web em 04/12/2017 ADSORPTION OF BIODIESEL CONTAMINANTS BY SURFACE-MODIFIED BAGASSE FIBERS. Sugarcane bagasse fibers chemically modified on its surface were used to adsorb contaminants from biodiesel. Two biodiesel samples were used as adsorbates: crude and washed biodiesel. The contaminants were mainly glycerol and water, but also ions, and methanol. The biodiesel is usually washed, in order to remove most of the contaminants, but the procedure introdu… Show more

“…The sample was then placed in an oven, with temperature at 100 °C for 24 h. After this time, the sample was cooled in a desiccator and the sample was weighed again until the value remained constant, thus obtaining the moisture content by the difference between the initial and final masses, through Eq. 3, according to ASTMD 6304 13 .…”

“…A escolha da matéria-prima demanda de um estudo de viabilidade consistente, uma vez que os custos com insumos de acordo com Bergmann et al (2013) pode representar até 80 % do custo de produção (SANTOS; SILVA; TAVARES, 2018). O método mais utilizado pelas indústrias produtoras de biodiesel é a transesterificação, reação entre um trialcilglicerol e um álcool de cadeia curta (comumente metanol e etanol), que sob ação de um catalisador ácido ou básico, resulta em uma mistura de ésteres que é constituída de biodiesel e glicerina, o segundo, um coproduto que em altas concentrações no biodiesel pode provocar problemas de armazenamento, formação de depósitos, entupimento de bicos injetores do motor e emissões de aldeídos (OLIVEIRA et al, 2017). A Figura 1 apresenta um esquema da reação de transesterificação na produção de biodiesel.…”

“…Current studies report low cost adsorbents to remove contaminants in aqueous effluents: sugar cane (Almeida et al, 2019;Gorgulho et al, 2018;Oliveira et al, 2018;Paula et al, 2017), chitosan The wild cane (Gynerium Sagittatum) belongs to Poaceae family and can be found throughout Brazil throughout the year. This fiber is widely used in handicraft production by the residents of Ilha de Maré, Bahia, Brazil (MMA, 2011).…”
