Abstract

The influence of feedstock and pyrolysis temperature on biochar properties has been extensively studied. This study used scanning electron microscopy (SEM) and electron dispersive X-ray analysis (EDX) to observe surface morphology properties of the biochars produced from broiler litter (BL), saw dust (SD), furfural residue (FR) at 300-700 °C. The SEM images showed that the biochars from SD and FR clearly retained fibrous structures of the feedstocks and were rich in macro-pores. Similarly, the FR-derived biochars produced at 500 and 700 °C contained larger quantity of pores compared to that of the FR300. The particles with irregular shape on the surface of these biochars reduced with increasing temperature, suggesting that their surface morphology changed greatly during charring at higher temperature. Mineral elements (e.g. K, Mg, and P) were found in the FR-derived biochars. The abundant pores and minerals in the biochars are helpful for ameliorating soil through the supplies of micro spaces and mineral nutrition .
