Sorption properties of activated carbons obtained from corn cobs by chemical and physical activation
The paper presents results of a study on obtaining activated carbon from common corn cobs and on its use as adsorbent for removal of pollution from liquid and gas phases. The crushed precursor was… Expand
Comparison of physicochemical and sorption properties of activated carbons prepared by physical and chemical activation of cherry stones
Abstract Cherry stones were used as a precursor for the preparation of activated carbons by physical and chemical activation with CO 2 and KOH, respectively. The effect of pyrolysis temperature (500… Expand

A technology of obtaining active carbon from plum stones by chemical activation with KOH is described. The effect of carbonisation temperature as well as activation procedure on the textural… Expand
Activated carbons modified with sewage sludge derived phase and their application in the process of NO2 removal
Abstract Highly porous wood-based activated carbon was treated with species extracted from the surface of pyrolyzed sewage sludge. Their deposition on the external surface was visible by a change of… Expand
The influence of activation procedure on the physicochemical and sorption properties of activated carbons prepared from pistachio nutshells for removal of NO2/H2S gases and dyes
Abstract Pistachio nutshells were chosen as activated carbons precursor because current method of their disposal - combustion - is not profitable due to the low calorific value. Carbonaceous… Expand
Reactive adsorption of NO2 at dry conditions on sewage sludge-derived materials.
Composite inorganic-carbonaceous adsorbents were obtained by pyrolysis of sewage sludge at 500, 650, and 950 degrees C for various periods of time. They were used as media for reactive adsorption of… Expand
Effect of activation method on the physicochemical properties and NO2 removal abilities of sorbents obtained from plum stones (Prunus domestica)
Abstract Carbonaceous adsorbents from plum stones were obtained by physical and chemical activation and used as nitrogen dioxide adsorbents. The effect of activation procedure on the physicochemical… Expand
The effect of chemical activation method on properties of activated carbons obtained from pine cones
A method for obtaining carbonaceous adsorbents from pine cones by chemical activation with NaOH is described. Activated carbons were obtained by two methods of activation (physical mixing and… Expand
Hydrogen sulphide removal on carbonaceous adsorbents prepared from coffee industry waste materials
Abstract The sorption properties of chars and activated carbons obtained from coffee industry waste materials toward hydrogen sulphide are characterised. The effects of pyrolysis temperature and… Expand
Carbonaceous adsorbents prepared by physical activation of pine sawdust and their application for removal of NO2 in dry and wet conditions.
Carbonaceous adsorbents from sawdust pellets from coniferous trees (pines) were obtained by CO(2) activation and used as nitrogen dioxide adsorbents. Activation was performed at 800 degrees C for… Expand
