Calorimetric study of activated carbons impregnated with CaCl2

Impregnated Carbons for the Adsorption of H2s and Mercaptans

Activated carbon has been used for many years for the adsorption of H2S and Mercaptans from natural gas streams, carbon dioxide, and sewage vents. It is widely thought that the carbon pore surface catalyses the oxidation of HzS to elemental sulfur and higher oxidized forms of su l fd2 . However, due to the poor loading capacities achieved at ambient conditions, most commercial activated carbon ...

Comparative Study of the Activated Carbons: Part-i:

It is found from literature that the activated carbon prepared from various raw materials are being examined and reported for more characteristics than prescribed under the relevant IS codes. However, some of the characteristics prescribed by the IS codes are not being examined by the earlier investigators. A database comprising the physico-chemical characteristics of the activated carbon prepa...

Study the Static Adsorption/Desorption of Formaldehyde on Activated Carbons

Microwave-assisted regeneration of activated carbons loaded with pharmaceuticals.

The purpose of this work was to explore the application of microwaves for the regeneration of activated carbons spent with salicylic acid, a metabolite of a common analgesic frequently found in wastewater from the pharmaceutical industry. The exhausted carbon was treated in a quartz reactor by microwave irradiation at 2450 MHz at different temperatures and atmospheres, the regeneration efficien...

Pyrolysis of Activated Carbons Exhausted with Organic Compounds

The regeneration of activated carbons used for the decontamination of water and wastewater polluted with organic compounds related to the pharmaceutical industry, has been studied in this work. To this end, the pyrolysis of exhausted activated carbons was performed in a quartz reactor. The influence of the pyrolysis of saturated activated carbons on their adsorptive capacities and porous struct...
