RECYCLING OF Eucalipto cloeziana UNDER BIOCHAR DIFFERENT PYROLISIS TEMPERATURES

Abstract

In the thermal decomposition of the biomass, products which include carbon compounds are generated. Biochar, a by-product of decomposition, has been efficient in retaining carbon, as well for agricultural and environmental management. Thus, the objective of this research is to evaluate the thermal stability and the recalcitrance of eucalyptus-derived bioburden due to different heating rates and pyrolysis temperatures. To do so, biochar were produced from Eucalyptus cloeziana at nine pyrolysis temperatures and three heating rates, and thermogravimetric analysis, determination of C and functional groups by FTIR were performed. Increasing the aromaticity of the biochromes produced, at higher temperatures, results in an increase in their recalcitrance, as demonstrated by the increase in thermal resistance and the oxidation by acid dichromate.

Composition, Ageing and Herbicidal Properties of Wood Vinegar Obtained through Fast Biomass Pyrolysis

“…The weed killing capacity of this bio-product of biomass pyrolysis is important as it will confer economic value to the bio-product. Examples of other biomass pyrolysis bio-products with market value are biochar, which is used as a permanent carbon store [41][42][43][44][45][46], bio-oil, used as a fuel [47][48][49], and bio-bitumen, used as an asphalt additive [50].…”
