dc.description.abstract | Chemical-looping combustion (CLC) is an attractive process in CO2 capture, especially when solid
oxygen carriers are used in it. The main requirements for oxygen-transporting materials include appropriate
oxidation (in air) and reduction (in the presence of fuel) ability. In the paper a conceptual proposition for
CLC-related processes with the application of solid oxygen carriers oxidized in both air and CO2 atmosphere has
been presented. The possibility of the “looping” process on the same carriers using both CO2 and air atmosphere as
an oxidizing agent allows us to enrich the concept of CLC and related processes by proposing a cyclic
recirculation of the produced CO2 back to the installation. The oxidizing of solid oxygen carrier in a CO2
atmosphere is accompanied by CO emission from the plant. This toxic gas could be transformed into a useful
product in any chemical process. It is possible to combine the looping processes with manufacturing of any
appropriate morphological form of carbon in the cyclic CO disproportionation process. The combined process
could lead to a lower CO2 emissions to the environment. SrTiO3 doped by Cr (STO:Cr) and a mixture of
TiO2- and Ni-based compounds (TiO2-Ni) were investigated as oxygen transporting materials. The experiment
methodology based on thermogravimetric, diffraction and spectroscopic studies was shown. Thermogravimetric
(TGA) and Powder Diffraction (XRD) measurements were provided in-situ during a few cycles in a reducing
(Ar+3 % H2) and oxidizing environment. Moreover, the STO:Cr powders were characterized ex-situ by the X-ray
Photoelectron Spectroscopy (XPS) method. It was found that in tested conditions the cyclic process of the
investigated powders’ oxidation and reduction is possible. Satisfactory results considering the oxygen transport
capacity was obtained for the TiO2-Ni sample. | pl_PL |
