"Low-temperature carbonatization of metal oxides";
Energy Procedia, 158 (2019), 4870 - 4881.



English abstract:
In the present work carbonatization of selected metal oxides was investigated at temperatures below 100°C and CO2 pressures of 1-55 bar (25°C) and 110 bar (60°C) by in-situ powder diffraction, as well as experiments in a pressure reactor. Moisture was confirmed to be a crucial requirement for any successful carbonatization, as under dry conditions always the initial metal oxide was recovered. Under the applied conditions a successful carbonatization of CaO, MnO, ZnO, CoO and PbO was achieved, highlighting,that although commonly studied at high temperatures, carbonatization of metal oxides can also be successfully operated in the presence of moisture with an elevated CO2 pressure as driving force.
