无灰煤配煤炼焦对热塑性与焦炭质量的影响研究进展
Research progress on the influence of Hypercoal blending and coking on thermoplasticity and coke quality
摘要
Abstract
The preparation of Hypercoal by thermal extraction of low rank coal and its application to coal blending and coking are of great significance for the efficient utilization of low rank coal resources and the improvement of met-allurgical coke quality.Combined with the preparation principle of Hypercoal,the research progress on the applica-tion of Hypercoal in the field of coal blending and coking is summarized in terms of the influencing factors of Hyper-coal preparation,the influencing factors of the high thermoplasticity of Hypercoal,and the influence of Hypercoal co-king on the thermoplasticity of coking coal and the quality of coke.The results showed that the swelling effect of polar solvents,extraction temperature,thermal dissolution time and solid-liquid ratio all had an effect on the preparation of Hypercoal;in the extraction of Hypercoal,the solvent interacts with the coal and disperses the coal structure,which changes and reorganizes during pyrolysis,and the stronger swelling effect of polar solvents makes the coal structure more dispersed and the extraction effect better;the swelling effect of polar solvents,higher extraction tem-perature,proper thermolysis time and solid-liquid ratio can lead to the formation of a certain aromatic structure of the Hypercoal,which makes it have good thermoplasticity,but still requires further research on the structure of the Hy-percoal and the role of the mechanism in the coking process and its high thermoplasticity mechanism.When applied in the field of coal blending and coking,Hypercoal can effectively improve the thermoplasticity of coking coal,im-prove the carbonaceous structure,pore structure and optical texture of coke,and thus have a significant effect on the quality of coke.关键词
