Sawdust-derived Biochar: characterization and Co2 adsorption/desorption study

Sawdust-derived Biochars (SDB) was prepared in a stainless steel fixed bed pyrolyser of 43 mm height and 60 mm internal diameter at four different operating temperatures ranging from 450 to 850°C. SDB physico-chemical characterization such as surface area, functional groups and surface morphology we...
