Info

Characteristics <strong>of</strong> Carbonized <strong>Rice</strong> Residues • Carbonized rice husks are a very light material with a microporous structure and a bulk density <strong>of</strong> about 0.150 g cm−3 (Nakajima 1986). • The structure <strong>of</strong> rice husks is preserved in the carbonization process but carbonized husks break easily, especially if carbonized at high temperatures. 8
<strong>Biochar</strong> preparation and characterization • <strong>Biochar</strong> was found to be alkaline in nature (pH 8.2). <strong>Rice</strong> husk biochar produced <strong>under</strong> temperatures between 500 and 600 ℃, showed a noticeable increment in silicon, calcium, potassium and magnesium content. 9
