Influences of pyrolysis condition and acid treatment on properties of durian peel-based activated carbon

Physico-chemical characterization of biochars from vacuum pyrolysis of South African agricultural wastes for application as soil amendments

“…Biochars from vacuum pyrolysis resulted in higher surface areas compared to biochars from slow pyrolysis due to the higher reaction rate; therefore greater devolatilization was obtained using vacuum pyrolysis. Similar observations were made by other researchers for different biomasses [45,46]. Larger surface area would be beneficial in soil as it indicates higher sorption capacity of a biochar.…”

Preparation and characterization of activated carbon produced from rice straw by (NH4)2HPO4 activation

“…This is due to the release of volatile matters through pore opening and biomass gasification during activation at high temperatures. Comparing with the relevant literatures, activated carbon yield 45.12% for RS-3 at 600°C is higher than for those made from other agricultural wastes with different activation methods under the same activation temperature, such as soybean oil cake of 6.22-16.22% (Tay et al, 2009) and durian peel of 18.74-21.32% (Nuithitikul et al, 2010).…”

Mesoporous activated carbon from inherently potassium-rich pokeweed by in situ self-activation and its use for phenol removal

“…This was supposed to be essentially induced by the active in situ chemical/physical activation effects of the naturally enriched potassium compounds in the feedstock. The presence of significantly developed mesopores in combination with micropores in the as-prepared AC-1, is favorable to improve its adsorption capacities for large molecules of adsorbates, as described in literatures [37,38].…”
