The CoO oxygen carriers were synthesized by sol-gel combustion synthesis method

and the reaction characteristics of CoO and Yangquan anthracite(YQ) and the kinetics were investigated through TG/DTG analysis. The results show that

the ignition temperature of the reaction between YQ coal and CoO was high

the volatile release characteristic index

flammability index and combustion characteristic index were small

indicating the combustion and burnout characteristics is not very good. The kinetic analysis indicates that

the reaction between the CoO and YQ coal belongs to Coats-Redfern model

and according to this model the activation energy and pre-exponential factor of the reaction are calculated respectively with different values of n. It founds that the activation energy is large and the pre-exponential factor is small

so the reaction is not easy to occur.
