摘要:

生物质化学链气化(chemical looping gasification, CLG)为生物质能源的利用开辟了新途径,氧载体在CLG过程中具有重要作用,其性能是影响CLG反应过程的关键因素。本文重点阐述了CLG技术中氧载体的性能评价指标、类型、制备方法及其对CLG过程中产生焦油的影响。通过对比分析目前研究成果,指出Fe基氧载体在生物质CLG过程中应用最广泛,而Ni基氧载体具有较高的活性和较大的载氧能力,且对于CLG副产物焦油具有较高的催化转化效率。未来该领域研究的重点方向是开发高活性且环境友好的氧载体,推进CLG工艺的工业应用。本文为今后生物质CLG氧载体的开发与优化提供了借鉴。

Abstract:

Biomass chemical looping gasification (CLG) is a promising approach for the utilization of biomass energy. The oxygen carrier plays an important role in the CLG process, and its performance is the key factor affecting the CLG process. In this paper, the performance evaluation indexes, the types of oxygen carriers, preparation methods and their effects on tar yield in CLG technology were reviewed. Through analysis and comparison of current research results, it was pointed out that Fe carrier is the most widely used in the process of biomass CLG, and Ni carrier has higher activity, larger oxygen carrying capacity, and higher catalytic conversion efficiency for tar. Therefore, Ni carrier shows better application prospects. In the future, the key direction in this field is the development of highly active and environmental-friendly oxygen carriers, thus promoting the industrial application of CLG process.
