Formation of nanoporous carbon materials in conditions of thermocatalytic synthesis

A study of the volatile products formed in the process of thermocatalytic destruction of a hardwood and the carbonizates on its basis in the presence and absence of acidic (H3PO4) and alkaline (NaOH) activators was performed by thermogravimetry/mass spectrometry (TG/MS) method. Ranges of formation temperatures and the amount of water and the main gaseous products were determined. It is shown that, in the case of activation with alkali, the chemical composition and structure of the precursor have a pronounced effect on the process. Nanoporous carbon materials with high indices of the porous structure were obtained. (c) 2013 Elsevier B.V. All rights reserved.
