Research on the carbon deposition characteristics of the metal oxygen carrier
Abstract：TGA（Thermal Gravimetric Analysis） was used to research on Ni-based, Fe-based, Cu-based and Co-based prepared oxygen carriers, and the TG test curves reflect the carbon deposition characteristics of different prepared oxy- gen carriers and indicate that the Cu-based oxygen carrier can restrain carbon deposition to some extent. When com- bustion reaction of CO was conducted in the tube furnace, adopting the method of feeding water vapour into the furnace can avoid carbon deposition effectively. Finally, the XRD （X-Ray Diffraction） was used to scan the reaction product to evaluate the anti-carbon effect of the experiment. Compared with the no steam condition, it can be found that the char- acteristic peaks of carbon are disappeared on feeding steam condition, and carbon deposition controlled by the addition of steam is confirmed further.
