Abstract

Biochar is a carbon product produced from the pyrolysis of animal and plant wastes and is mainly used as a soil conditioner. However, biochar’s ability to improve soil varies depending on its microscopic properties. Therefore, it is necessary to study the characterization properties of biochar before large-scale application. In this study, three common plant wastes (Wedelia trilobata, Shaddock peel, Bagasse) were selected to produce biochar and carry on the characterization analysis on them. Biochar produced at different pyrolysis temperatures (300 ℃, 600 ℃) were characterized using a suite of analytical techniques, including SEM, EDS, FTIR, XRD. When the pyrolysis temperature of biochar increased from 300 ℃ to 600 ℃, the oxygen (O) ratio in SPB and BB decreased from 16.46% and 13.18% to 9.19% and 3.37% respectively, and the degree of carbonization and specific surface area increased correspondingly. In addition, high temperatures will decompose some functional groups of biochar, and the PH values of biochar prepared at different pyrolysis temperatures are different. Such properties of biochar will be useful in selecting suitable soil conditioners for usage in geo-engineering infrastructure.
