摘要
化学链技术是一种清洁高效的新型技术。煤、石油焦、生物质等固体原料的化学链技术处于初步研发阶段。氧载体的研发、反应器的研制和工艺性验证试验是核心研究方向。双组分化学链氧解耦(CLOU)材料可以在反应条件下解离出气相氧,提高反应速率,是未来氧载体的研发方向。流化床燃料反应器反应速率高、易于放大,移动床燃料反应器原料转化率高、气体产物纯度高。这2种燃料反应器模式都将继续发展、完善,并会长期共存。催化气化技术可以提高焦炭的气化速率,有望解决固体原料转化率低、反应速率慢等难题,从而促进固体原料化学链技术的发展,而化学链部分氧化技术也有望发展成为先进的固体原料气化技术,并且拥有十分广阔的应用前景。
Chemical looping is a novel clean carbonaceous conversion technology. Chemical looping technology with coal, petroleum coke and biomass as solid feedstock is now at its early development stage. Oxygen carrier, reactor and processing demonstration are the three most important research topics. Chemical looping oxygen uncoupling （CLOU） materials with dual active components release gaseous oxygen at reaction temperature, increasing the rate of solid fuels, and thus is the direction of the promising oxygen carrier development. Fuel reactor is the key component for the design of a chemical looping system. Fluidized bed has the advantages of high reactivity and the ease to scale up, while moving bed is desirable given the high fuel conversion rate and gas purity. Further achievements are expected on both fluidized bed and moving bed, and they will exist as the two dominating modes for the fuel reactor operation. Catalytic gasification is likely to accelerate the development of solid-fueled chemical looping. Chemical partial oxidation technology also emerges as a novel gasification method with broad application.
