carbon dioxide is a major greenhouse gas that contributes to the global warming by more than %60. absorption has been widely used to treat high concentrations of co2 in synthesis gas production, hydrogen manufacturing, and natural gas processing. the most well established method to capture co2 is its removal by absorption into amine solutions in the presence of activators. in this research, co2...

Abstract Background In recent years, special attention has been focused on the use of natural adsorbents as an alternative to replace conventional adsorbents, based both environmental and economical points view. The study aimed produce absorbent (activated carbon) from two local agricultural wastes: mango seeds (MS) date stones (DS) their uses in removal contamination fluid nutrient. Chemical p...

this research was done in order to determine the basic criteria for “tehran oil refinery effluemt treatmentunit” to prove the feasibility of the application of powdered activated carbon in aeration zone of activated sludge system. the main stages of this research included: determination of qualitative and quantitative characteristics of raw wastewater preparation of two pilot scale units of act...

Carbon nanostructures are famous structures which are used in several industries such as separation, treatment, energy storage (i.e. methane and hydrogen storage), etc. A successful modeling of activated carbon preparation is very important in saving time and money. There are some attempts to achieve the appropriate theoretical modeling of activated carbon preparation but most of them were almo...

Carbon-based materials have become an indispensable component in a myriad of domestic and industrial applications. Most the carbon-based end-of-life products discussed this review end up landfills. Where recycling is available, it usually involves production lower-value products. The allotropic nature carbon has been analysed to identify novel that could be obtained from used products, which al...

During the last years our research group has been studying the use of industrial vegetable wastes as grape stalks and exhausted coffee to remove metals ions such as Ni(II), Cu(II), Pb(II), Zn(II), Cd(II) or Cr(VI) and Cr(III) in aqueous solution from the point of view to use these wastes as biosorbents in a low cost alternative to activated carbon for wastewater treatment. The optimal experimen...

the purpose of this study is the utilization of furfural residue for heating energy and activated carbon production. to evaluate the energy production of the residue, bulk density, melting point, and heating value were measured. furthermore, moisture, ash, volatile compounds, fixed carbon, lignin, and elements were determined. ash and volatile content average were measured at 15.4% and 68.9%, r...

Introduction Modification of the precursors or ready activated carbons permits getting materials of improved adsorption and catalytic properties or of specific acid-base or hydrophobic-hydrophilic character. Particularly promising are the activated carbons enriched in nitrogen because of wide possibilities of use of such materials. In particular, they can find applications related to protection...
