Resumo: | In lignocellulosic biomass, the volatile matter can vary from 65 to 85%. Different standards are described in the literature for obtaining this parameter. However, it is observed that some studies of regression models have not considered these differences. They create a volatile matter content database, where the standards for obtaining the same parameter are different. Thus, the objective of the study was to verify whether different standards for volatile matter present statistically equal values. That is if they can be compared with each other, without danger of bias. For this, three types of biomasses of Brazil used were used (eucalyptus chips, pine chips, and sugarcane bagasse). The samples were collected, size reduction, size separation, and stored in the laboratory. Three standards of the American Society for Testing and Materials (ASTM D1762, ASTM E872, ASTM D3175) and one standard of the International Organization for Standardization (ISO 18123) were tested. The experimental design was completely randomized, consisting of four treatments and five replications. The central limit theorem was tested in some literature databases of the volatile matter. The results showed statistical differences when changing the type of standard used. For eucalyptus sawdust, the four standards resulted in methodologies with different averages. Still, the central limit theorem was not observed in some databases of different articles. This was explained by the non-standardization of a single standard when grouping data from different works. Therefore, different volatile content standards produce different results and when comparing values, it is important to take this assumption into account. |

Sin embargo, se observa que en algunos estudios de modelos de regresión no consideraron estas diferencias. Crean una base de datos de contenido de materiales volátiles, donde los estándares para obtener un mismo parámetro son diferentes. Así, el objetivo del estudio fue verificar si diferentes estándares para el contenido de materiales volátiles presentan valores estadísticamente iguales. Para ello, se utilizaron tres tipos de biomasa de Brasil (astillas de eucalipto, astillas de pino y bagazo de caña de azúcar). Las muestras se recolectaron, se redujeron de tamaño, se separaron y se almacenaron en el laboratorio. Se probaron tres estándares de la Sociedad Estadounidense de Pruebas y Materiales (ASTM D1762, ASTM E872, ASTM D3175) y un estándar de la Organización Internacional de Normalización (ISO 18123). El diseño experimental fue completamente al azar, con cuatro tratamientos y cinco repeticiones. El teorema del límite central se probó en algunas bases de datos de literatura de contenido de material volátil. Los resultados mostraron diferencias estadísticas al cambiar el tipo de estándar utilizado. Para el aserrín de eucalipto, los cuatro estándares dieron como resultado metodologías con diferentes medios. Aún así, el teorema del límite central no se observó en algunas bases de datos de diferentes artículos. Esto se explica por la no estandarización de un solo tipo de norma en la agrupación de datos de diferentes trabajos. Por lo tanto, diferentes estándares para materiales volátiles producen resultados diferentes.Na biomassa lignocelulósica, o teor de materiais voláteis pode variar de 65 a 85%. Diferentes normas são descritas na literatura. No entanto, observa-se que em alguns estudos de modelos de regressão não consideraram essas diferenças. Eles criam um banco de dados de teor de materiais voláteis, onde as normas para obtenção do mesmo parâmetro são diferentes. Assim, o objetivo do estudo foi verificar se diferentes normas para o teor de materiais voláteis apresentam valores estatisticamente iguais. Para isso, foram utilizados três tipos de biomassas do Brasil (cavaco de eucalipto, cavaco de pinus e bagaço de cana). As amostras foram coletadas, reduzidas de tamanho, separadas de tamanho e armazenadas em laboratório. Três padrões da American Society for Testing and Materials (ASTM D1762, ASTM E872, ASTM D3175) e um padrão da International Organization for Standardization (ISO 18123) foram testados. O delineamento experimental foi inteiramente casualizado, com quatro tratamentos e cinco repetições. O teorema do limite central foi testado em algumas bases de dados da literatura de teor de materiais voláteis. Os resultados mostraram diferenças estatísticas ao mudar o tipo de norma utilizada. Para a serragem de eucalipto, os quatro padrões resultaram em metodologias com médias diferentes. Ainda assim, o teorema do limite central não foi observado em algumas bases de dados de diferentes artigos. Isso se explica pela não padronização de um único tipo de norma no agrupamento de dados de diferentes obras. Portanto, diferentes normas de materiais de voláteis produzem resultados diferentes.Research, Society and Development2021-10-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2047610.33448/rsd-v10i12.20476Research, Society and Development; Vol. 10 No. 12; e291101220476Research, Society and Development; Vol. 10 Núm. 12; e291101220476Research, Society and Development; v. 10 n. 12; e2911012204762525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/20476/18598Copyright (c) 2021 Diego Aleixo da Silva; Ana Larissa Santiago Hansted; Gabriela Tami Nakashima; Elias Ricardo Durango Padilla; Julio Cesar Pereira; Fabio Minoru Yamajihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Diego Aleixo daHansted, Ana Larissa Santiago Nakashima, Gabriela Tami Padilla, Elias Ricardo Durango Pereira, Julio Cesar Yamaji, Fabio Minoru 2021-11-14T20:26:51Zoai:ojs.pkp.sfu.ca:article/20476Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:06.851045Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
