Research progress on oxygen carrier in chemical-looping combustion of methane
The proportion of natural gas is increasing in the energy structure of China. Methane, the main component of natural gas,produces large amounts of CO and CO,2, in the combustion process. Chemical-looping combustion technology of methane is one of the important technologies for CO,2, capture, with the advantages of energy cascade utilization and NO,x, avoidance. While improving energy utilization rate, high purity CO,2, can be obtained, which is beneficial to the subsequent storage and transformation and utilization, and is of great significance to the implementation of the “double carbon” strategy of our country. The main factor affecting the chemicallooping combustion technology is oxygen carrier, so the choice of oxygen carrier is particularly important. The basic principle and characteristics of chemical-looping combustion technology were presented, and the research progress of nickel base, copper base, iron base, manganese base, composite metal and non-metallic oxygen carrier in chemical-looping combustion with methane as fuel was summarized. It is found that the reaction performance of oxygen carrier is mainly affected by its oxygen carrying capacity, reactivity and sintering resistance. At the same time, the future development prospect of oxygen carrier in chemical-looping combustion technology of methane is prospected.
