Gas Chromatographic Study of Specific Physisorption by Activated Carbons

CO2 adsorption by activated templated carbons.

Highly porous carbons have been prepared by the chemical activation of two mesoporous carbons obtained by using hexagonal- (SBA-15) and cubic (KIT-6)-ordered mesostructured silica as hard templates. These materials were investigated as sorbents for CO(2) capture. The activation process was carried out with KOH at different temperatures in the 600-800°C range. Textural characterization of these ...

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

Comparative characterization study of microporous carbons by HRTEM image analysis and gas adsorption.

The present work presents a useful comparison of micropore size distributions (MPSDs) obtained from gas adsorption and image analysis of high-resolution transmission electron micrographs. It is shown that the MPSD obtained for a chemical activated carbon is concordant with that obtained from CO2 adsorption. In addition, this technique has allowed us to obtain the MPSD of a carbon molecular siev...
