High-temperature CO sorption over LiSiO synthesized from diatomite: study of sorption heat and isotherm modeling.

The LiSiO seems to be an excellent sorbent for CO capture at post-combustion. Our work contributes to understanding the effect of the natural Algerian diatomite as a source of SiO in the synthesis of LiSiO for CO capture at high temperature. For this purpose, we use various molar % (stoichiometric and excess) of calcined natural diatomite and pure SiO.
