alternative, oxy-fuel combustion is considered as a promising new approach for CO 2 capture. Oxy-fuel combustion technology involves the combustion of pulverized coal in a mixture of oxygen (as opposed to air) and recirculated flue gas (mainly CO 2 and H 2 O

Abstract  

Temperature programmed combustions (TPC) of Yang-Quan anthracite, Liao-Cheng lean coal and Li-Yan bituminous coal in oxy-fuel atmosphere were conducted in a thermogravimetric analyzer and characteristic parameters were deduced from the TG-DTG curves. The results showed that combustion got harder to progress as the coalification degree increasing. Within range of 40%, effect of heightening O2 concentration favored the combustion process, but beyond this zone, the effect leveled off. The model-fitting mathematical approach was used to evaluated the kinetic triplet (f (α), E, A) through Coats–Redfern method. The calculation showed that D 3-Jander was the proper reaction model and the evaluations of E and A validated the experimental results.

fossil fuels, so CO 2 capture and storage has been explored. Various methods, such as solvent absorption, adsorption, cryogenics, membranes, microbial, and denitrogenation (i.e., oxy-fuel combustion and chemical looping combustion) are used to capture
