Topics in Catalysis Aims and scope Submit manuscript


The CO2 absorption properties of potassium-based TiO2 sorbents prepared by calcining at various temperatures from 300 to 700 °C under N2 and air were investigated in a fixed bed reactor at 60 °C. The CO2 capture capacity of the sorbent was changed dramatically depending on the structure of the sorbent, which was affected by calcination atmosphere, as well as calcination temperature.
