Removal of mercury from natural gas by a new activated

Jul 25, 2017 The raw material from olive stones was prepared by pyrolysis, chemical activation with phosphoric acid, and physical activation under steam. Two olive stone-based granular activated carbons were prepared: one with the virgin stones, while the other was impregnated with sulphur.

PDF CO 2 activation of olive stones carbonized under

It is well known that in chemical activation the effect of The aim of this work is to study the influence of phosphoric acid or zinc chloride is to restrict the formation pressure carbonization of olive stones prior to activation, of tar during carbonization, thus increasing the yield of the in order to provide a further understanding of the ...

Removal of Phenol and 4 Chlorophenol from Aqueous

The olive stones were collected from an olive plant discharge in the Sig area (west of Algeria), washed, dried overnight at 383 K and crushed in a Vierzen grinder. The particles were then soaked in 50% phosphoric acid solution for 3 h at 443 K. The residue was washed in 0.1 N hydrochloric

Effect of Different Olive Stone Particle Size on the Yield

This research was assessed the effect of different olive stone particle size on activated carbon production by KOH using the yield and surface area response. Three particle size ranges were examined, namely 1-2mm, 2-4.75 and the raw material in its original form.

Methanol Dehydration to Dimethyl Ether on Zr Loaded P

Activated carbons have been prepared by the chemical activation of olive stones with phosphoric acid and loaded with Zr. The addition of Zr to the phosphorus-containing activated carbons resulted in the formation of zirconium phosphate surface groups. Gas phase methanol dehydration has been studied …

Frontiers About the Role of Porosity and Surface

A parent activated carbon is prepared by chemical activation of olive stones with phosphoric acid at 500 C and impregnation weight ratio of 3:1. This carbon is thermal treated in inert atmosphere at 900 C, producing porosity shrinkage, loss of 20% of surface area and less oxidized phosphorus groups.
