Microporosity in carbon blacks

Microporosity in carbon blacks

Microporous carbon blacks can be characterized by the same techniques as activated carbons, using the classical DR equation and comparison plots based on non-porous materials. The CO adsorption isotherm at 273 K, combined with 2 computer modelling, also leads to an assessment of microporosity. The results agree with independent techniques such as immersion calorimetry into liquids of variable m...

Microporosity Development in Coal-Based Carbon Foams

This paper presents a novel method of manufacturing carbon foams from coals with a bimodal porosity structure (macroand microporosity), by means of a carbonisation process at 450 or 475 °C that produces the carbon foam, followed by chemical activation with zinc chloride at 500 °C. The activation agent influences the development of macroporosity during the foaming step and gives rise to micropor...

The adsorption of 3,4-benzpyrene and pyrene by carbon blacks.

the previous paper it was reported that up to seven different aromatic polycyclic hydrocarbons, including 3,4-benzpyrene, were extracted with benzene from most carbon blacks made by the furnace process, but from no channel blacks (3). This difference cannot be explained on the basis of differences in raw materials. Soot formed in the laboratory from gas, which is similar to that used in the cha...
