Heterogeneity of biochar properties as a function of feedstock sources and production temperatures

Abstract: This study was conducted with a wide range of production temperatures aliphatic-C and aromatic-C was highly related to the production temperature. Raman properties.

“…The overall primary pyrolysis stage is completed at relatively low temperatures, around 500 °C (Neves et al, 2011), and yields a C-rich solid: charcoal or biochar, depending on its use. In general, the higher the temperature, the higher will be the pH, C, mineral and ash content, C stability and biochar aromaticity, porosity, and specific surface area, and the lower will be the volatile content and yield (Wu et al, 2012;Zhao et al, 2013;Zhang et al, 2015b).…”

“…At low amendment (1-5%) or substitution (< 25%) rates, BC has been found to maintain or improve plant growth as a result of increased nutrient availability (Headlee et al, 2014), reduced nutrient and water loss (Altland and Locke, 2013;Beck et al, 2011;Graber et al, 2010), and amelioration of peat acidity (Bedussi et al, 2015), though these effects may be BC-specific due to feedstock and pyrolysis influences on BC properties (McBeath et al, 2015;Zhao et al, 2013).…”

“…Los bajos valores en la CIC de los biochars BPC300 y BPC500 podrían estar relacionados con el bajo contenido en K, Ca, Mg y Na del residuo PC usado como materia prima. Por otra parte, la CIC de los biochars preparados a partir de E aumentó con la temperatura, lo cual concuerda con los resultados obtenidos por Zhao et al (2013).…”

“…Estos resultados sugieren que los residuos lignocelulósicos proporcionan una fuente estable de carbono aromatico lo cual resultaría muy útil para la producción de biochar con fines de captura de carbono. Teniendo en cuenta que el CF puede usarse para estimar la recalcitrancia del biochar (Zhao et al, 2013), los elevados contenidos en CF de los biochars BI y BII, sugieren que su uso para la fijación de carbono en suelos podría resultar apropiado. En cuanto al hollín HM, a pesar de haber sido producido a partir de un residuo lignocelulósico a altas temperaturas, tras el proceso de gasificación esta muestra presenta una composición casi idéntica en ceniza (45.91) y en CF (45.78), siendo su contenido en CF menor que el de BI y parecido al de BII.…”
