Electrosorption on Activated Carbon Textile

Abstract

Technol. 22 (1999) 9 and the means of oxygen transport from the gas-phase into the bulk-phase are questions that still have to be answered in future investigations. ConclusionWithin the bounds of the investigated process-parameters (temperature, pressure, concentration), the application of transient process control is not advantageous to the chosen system:With this simple example we have shown that the introduction of a concentration-programmed-reduction method provides information about the potential of the application of transient process control. This can be achieved very quickly and at low cost at an early stage in the laboratory. Further investigations are necessary on different catalyst systems, e.g. on those used in the production processes of acrylonitrile, sulphuric acid, methacrylic acid, phthalic anhydride, malenic anhydride etc. The potential of application for transient process control should be examined closely with the aid of CPR.

Electrochemically enhanced adsorption of phenol on activated carbon fibers in basic aqueous solution

“…In this way, the 34% enhancement of adsorption capacity of activated carbon was observed. The investigations of electrochemically enhanced adsorption for other organics have also been done [19,[25][26][27][28]. The results indicated that polarization of such carbon surfaces in a suitable electrolyte could, to some extent, improve the adsorption of ions and polarizable organic pollutants.…”
