Preparation of Activated Carbon from Lignin Obtained by Straw Pulping by Koh and K2co3 Chemical Activation
Activated carbon was prepared through chemical activation of lignin from a straw pulping precursor, using K2CO3 and KOH as chemical agents. To optimize the preparation method, the effect of the main process parameters (such as impregnation ratio, activation temperature and activation time) on the performance of the obtained activated carbon (expressed in terms of iodine number and yield of acti...
متن کاملPreparation of porous bio-char and activated carbon from rice husk by leaching ash and chemical activation
Preparation porous bio-char and activated carbon from rice husk char study has been conducted in this study. Rice husk char contains high amount silica that retards the porousness of bio-char. Porousness of rice husk char could be enhanced by removing the silica from char and applying heat at high temperature. Furthermore, the char is activated by using chemical activation under high temperatur...
متن کاملPreparation and Characterization of Activated Carbon from Lapsi (Choerospondias axillaris) Seed Stone by Chemical Activation with Potassium Hydroxide
Activated carbon (AC) was prepared from Lapsi seed stone by chemical activation with Potassium hydroxide at 400°C. The AC was characterized by pH, moisture content, Fourier transform-infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), methylene blue (MB) and iodine (I2) number. FT-IR spectra indicated the presence of various oxygen containing functional groups on the surface of AC...
متن کاملPreparation and Characterization of Activated Carbon Fibers from Liquefied Wood by ZnCl2 Activation
In this study, activated carbon fibers (ACFs) were prepared from liquefied wood by chemical activation with ZnCl2, with a particular focus on the effects of temperature and ZnCl2: liquefied wood-based fiber (LWF) ratio on yield, porous texture, and surface chemistry. The characterization and properties of these ACFs were investigated by nitrogen adsorption/desorption, Fourier transform infrared...
متن کاملPreparation of Activated Carbon from Pyrolyzed Rice Husk by Leaching out Ash Content after CO2 Activation
To prepare activated carbons with a high porosity and low ash content from pyrolyzed rice husk, the method of KOH or K2CO3 solution leaching after CO2 activation was investigated. The effects of KOH or K2CO3 concentration and leaching time on the yield, ash content, and textural properties of the activated carbon were studied, and the activated carbon prepared under the best conditions was char...
