Statistical modeling of activated carbon production from spent mushroom compost
Şeyda Karadirek,Hikmet Okkay 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.63 No.-
Activated carbons were prepared from spent mushroom compost using H3PO4 as activating agent. The effects of temperature (°C), impregnant ratio (H3PO4/biomass) and time (min) were determined by using Response Surface Methodology. The micropore area is above 75% of the total surface area. The activated carbon which has the maximum adsorption capacity with the largest specific surface area (1419.108 m2/g) was produced at the experimental conditions T = 450 °C, IR = 3.5:1 g/g and t = 50 min. The maximum activated carbon yield (56.2%) was obtained at 350 °C with an impregnant ratio of 1.5:1 g/g for 30 min.
