摘　　要：化学链催化燃烧是一种联合氧载体和催化剂实现低成本、高效率、低排放的燃烧技术。本文以铜矿石和负载SrTiO_(3)催化剂铜矿石为氧载体,以CH_(4)和平顶山煤为燃料,在流化床反应器中进行化学链催化燃烧实验,研究了不同工况下的反应性能。结果表明,负载SrTiO_(3)催化剂铜矿石氧载体在CH_(4)和平顶山煤的化学链催化燃烧过程中表现出更高的反应活性和抗积碳能力,能够有效提高CH_(4)和平顶山煤的转化率和CO_(2)选择性,同时具有良好的循环稳定性。本文的工作为利用铜矿石作为氧载体实现低成本、高效率、低排放的化学链催化燃烧提供了一种新思路和方法。Chemical looping catalytic combustion is a combustion technology that combines oxygen carriers and catalysts to achieve low-cost,high-efficiency,and low-emission combustion.In this paper,we use copper ore and copper ore loaded with SrTiO_(3) catalyst as oxygen carriers,and CH_(4) and Pingdingshan coal as fuels,to conduct Chemical looping catalytic combustion experiments in a fluidized bed reactor.We study the reaction performance under different conditions.The results show that the copper ore loaded with SrTiO_(3) catalyst exhibits higher reaction activity and anti-coking ability in the Chemical looping catalytic combustion process of CH_(4) and Pingdingshan coal,and can effectively improve the conversion rate and CO_(2) selectivity of CH_(4) and Pingdingshan coal,while maintaining good cyclic stability.This work provides a new idea and method for using copper ore as an oxygen carrier to achieve low-cost,high-efficiency,and low-emission Chemical looping catalytic combustion.
