Effect of the thermal treatment of anthracite from the Gorlovo Basin on its adsorption characteristics

Resumo

Various versions of the activation of a small fraction of anthracite from the Gorlovo Basin (Novosibirsk oblast) were studied: treatment in atmospheres of air, air–steam mixture (100–400°C), and carbon dioxide (500–800°C). The adsorptive capacity of the activated samples for decane vapor was measured with the aid of a TEOM 1500 PMA gravimetric analyzer. The qualitative composition of functional groups on the surface of the processed samples and their influence on the static and dynamic adsorptive capacity characteristics were determined by temperature-programmed oxidation (TPO) combined with mass-spectrometric analysis.
