Abstract
Sodium carbonate is a material that is very good sorbent of carbon dioxide from the atmosphere, and it is a reason of it is increasing importance in environmental protection. In order to improve it is sorption characteristics, activation of Na2CO3 was performed by mechanochemical procedure and monitoring of changes during the relaxation time. This research is based on differential thermal analysis with thermogravimetry, in order to determine the changes that occurred on the activated samples during the relaxation period under controlled conditions. Sodium carbonate was activated for 2 and 7 minutes in a vibro mill, and then the activated samples were deposited in at room temperature and atmosphere of carbon dioxide at a humidity of 95% for 96h.
Highlights
Material activation process has widely been accepted method for an additional energy introduction to the system in order to stimulate a control reaction
Authors have investigated the enhanced capacitance of carbon nanotubes through chemical activation (Frackowiak et al 2002), preparation of fibrous porous materials by chemical activation (Yue et al 2002), the effect of mineral matter on the physical and chemical activation of low rank coal and biomass materials (Vamvuka et al 2006), and compering different chemical reactions (Lillo-Ródenas et al, 2003)
The absorbed amount of gasses is a function of a material activated degree (Djordjević et al, 2020). In this communication we presented a control a change of mass inactivated and activated sodium carbonate aged for 96 hours in three different environments: in vacuum, carbon dioxide and room conditions
Summary
Material activation process has widely been accepted method for an additional energy introduction to the system in order to stimulate a control reaction. In this communication we presented a control a change of mass inactivated and activated sodium carbonate aged for 96 hours (relaxation period) in three different environments: in vacuum, carbon dioxide and room conditions.
