摘要：煤炭是我国能源安全的压舱石,煤气化作为煤炭清洁高效利用的核心技术对实现“碳达峰、碳中和”的战略目标具有重要作用。基于动态原位表征揭示煤气化反应机理并建立煤气化模型,对拓展煤炭和生物质等含碳物料作为气化原料的适用性,开发新型高效的气化技术有重要的理论指导价值。同时,煤灰的流动性质是影响气化炉长周期稳定运行的关键指标。本文详细综述了煤气化过程的动力学模型、热力学模型、床层模型以及煤灰流动性的预测模型,对比了各类模型的优缺点、适用的条件以及描述气化过程的性能,指出了不同方法建立的模型存在的问题,为气化过程的总包反应模型建立提供了理论指导,并针对煤气化过程反应模型未来的研究重点进行了展望。
Coal is the cornerstone of our energy security in China,and coal gasification,as a core technology for the clean and efficient utilization of coal,plays a crucial role in achieving the strategic goals of“peak carbon emissions”and“carbon neutrality”.Based on dynamic in-situ characterization to reveal the mechanism of coal gasification reactions and establish a coal gasification model has significant theoretical guidance value for expanding the applicability of carbon-containing materials such as coal and biomass as gasification feedstocks,and developing new efficient gasification technologies.Additionally,the flow properties of coal ash are a critical factor affecting the long-term stable operation of gasification furnaces.This paper provides a detailed review of the kinetics models,thermodynamics models,bed models,and predictive models for coal gasification processes.It compares the advantages and disadvantages of various models,their applicable conditions,and their abilities to describe gasification process performance.Furthermore,it identifies issues with the different methods used to establish models and offers prospects for future research focuses on reaction models in coal gasification processes.
