Optimization of Pyrolysis Conditions to Synthesize Adsorbent from Paper Mill Sludge

Parmila Devi and Anil K. Saroha
Abstract—Pyrolysis temperature is the key factor influencing the biochar yield. Experiments were performed to study the effect of pyrolysis temperature and additive dose on biochar yield. It was observed that biochar yield decreased with an increase in pyrolysis temperature and maximum yield was obtained at 300 oC. Conversely, surface area of the biochar increased with an increase in temperature and maximum surface area was obtained at 700 oC. The biochar was impregnated with different dosage of CaCO3 to analyze the effect of CaCO3 as an additive dosage on biochar properties. Addition of CaCO3 significantly affects the surface area and pore volume of the biochar, although it does not lead to significant change in biochar yield. Batch experiments were performed to explore the potential of raw and impregnated biochar as an adsorbent for the removal of pentachlorophenol (PCP). A removal efficiency of 86% and 97% was obtained with raw biochar and 3% CaCO3 impregnated biochar respectively.
