Resumo: | To choose the most efficient energy generation process, it is necessary to know the properties chemical and thermal effects of biomass. The shells and hedgehogs of Brazil nut (Bertholletia excelsa H.B.K.), generally treated as waste, they have aroused the interest of researchers in the energy sector due to their fuel properties. This work aims to evaluate the energetic properties of seed shells and hedgehogs Brazil nut to use them in the production of adsorbents. The physical-chemical and thermal tests of the biomasses were investigated by the techniques of Proximate Analysis (moisture, ash, volatiles and fixed carbon), Ultimate Analysis, High Heating Value (HHV), Lower Heating Value (LHV) and Thermogravimetry (TG/DTG). The adsorbents, CA-1 (shells) and CA-2 (hedgehog), were produced by chemical activation with ZnCl2 followed by carbonization at 500ºC for 90 min. The results of the characterization for the biomasses showed moisture between 8-9%, ash below 2.8%, and high volatiles (85%) LHV and HHV nearby, in the range between 15-17 MJ/kg. The yield of the process of obtaining activated carbon (~74%) was higher than the literature. The evaluation of the adsorbents regarding the methylene blue adsorption process proved to be efficient, activated carbon produced from the shells showed a greater adsorptive capacity when compared to the adsorbent produced from hedgehogs. Finally, the biomasses demonstrated a good energy potential and as an alternative to commercial activated carbon, promoting the use of waste and contributing as a possible solution in the search for low-cost precursor materials for adsorbents production. |

Las cáscaras y erizos de castaña (Bertholletia excelsa H.B.K.), generalmente tratadas como residuos, han despertado el interés de investigadores del sector energético por sus propiedades combustibles. Este trabajo tiene como objetivo evaluar las propiedades energéticas de las cáscaras de semillas y erizos de castaña para utilizarlos en la producción de adsorbentes. Los ensayos fisicoquímicos y térmicos de las biomasas se investigaron mediante las técnicas de Análisis Inmediato (humedad, cenizas, volátiles y carbono fijo), Análisis Elemental, Poder Calorífico Superior (PCS), Poder Calorífico Inferior (PCI) y Termogravimetría (TG/DTG). Los adsorbentes, CA-1 (conchas) y CA-2 (erizo), se produjeron mediante activación química con ZnCl2 seguida de carbonización a 500ºC durante 90 min. Los resultados de la caracterización para las biomasas mostraron humedad entre 8-9%, cenizas por debajo de 2.8%, altos niveles de volátiles (85%) PCI y PCS cercanos, en el rango de 15-17 MJ/kg). El rendimiento del proceso de obtención de carbón activado (~74%) fue superior al de la literatura. La evaluación de adsorbentes con respecto al proceso de adsorción con azul de metileno resultó ser eficiente, y el carbón activado producido a partir de las conchas mostró una mayor capacidad adsorbente en comparación con el adsorbente producido a partir de erizos. Finalmente, las biomasas mostraron un buen potencial energético y como alternativa al carbón activado comercial, promoviendo el uso de residuos y contribuyendo como una posible solución en la búsqueda de materiales precursores de bajo costo para la producción de adsorbentes.Para escolher o processo mais eficiente de geração de energia é necessário conhecer as propriedades químicas e térmicas da biomassa. As cascas e os ouriços da castanha do Brasil (Bertholletia excelsa H.B.K.), geralmente tratados como resíduos, têm despertado interesse de pesquisadores do setor energético devido as suas propriedades carburantes. Este trabalho visa avaliar as propriedades energéticas das cascas da semente e dos ouriços da castanha do Brasil para utilizá-los na produção de adsorventes. Os ensaios físico-químicos e térmicos das biomassas foram investigados pelas técnicas de Análise Imediata (umidade, cinzas, voláteis e carbono fixo), Análise Elementar, Poder Calorífico Superior (PCS), Poder Calorífico Inferior (PCI) e Termogravimetria (TG/DTG). Os adsorventes, CA-1 (cascas) e CA-2 (ouriço), foram produzidos por ativação química com ZnCl2 seguida de carbonização à 500ºC por 90 min. Os resultados da caracterização para as biomassas mostraram umidade entre 8-9%, cinzas abaixo de 2,8%, elevados teores de voláteis (85%), PCI e PCS próximos, na faixa entre 15-17 MJ/kg. O rendimento do processo de obtenção dos carvões ativados (~74%) foram superiores a literatura. A avaliação dos adsorventes quanto ao processo de adsorção do azul de metileno mostrou-se eficiente, sendo que o carvão ativado produzido das cascas apresentou uma maior capacidade adsortiva quando comparado ao adsorvente produzido a partir dos ouriços. Por fim, as biomassas demonstraram um bom potencial energético e como uma alternativa ao carvão ativado comercial, promovendo o aproveitamento dos resíduos e contribuindo como uma possível solução na busca por materiais precursores de baixo custo para a produção de adsorventes.Research, Society and Development2021-02-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1269810.33448/rsd-v10i2.12698Research, Society and Development; Vol. 10 No. 2; e53310212698Research, Society and Development; Vol. 10 Núm. 2; e53310212698Research, Society and Development; v. 10 n. 2; e533102126982525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/12698/11572Copyright (c) 2021 Cristiane Daliassi Ramos de Souza; Kleyner de Carvalho da Silva https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Cristiane Daliassi Ramos de Silva , Kleyner de Carvalho da2021-03-02T09:32:39Zoai:ojs.pkp.sfu.ca:article/12698Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:12.364013Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
