Progress on reaction models for coal gasification processes
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.
