为了突破山西焦化产业面临的优质炼焦煤资源紧缺、产能过剩、结构单一和产业链延伸不足的困境，对高硫炼焦煤资源进行高效转化利用实现降本增效，通过调整产品结构生产气化焦或民用洁净焦延伸产业链促进企业转型发展，具有重要的科学意义和应用价值。本项目基于煤热解挥发分中活性氢自由基可选择性活化诱导C-S键和原位供氢的前期研究，利用同步辐射原位热解装置、同步焦化装置和梯级焦炉试验装置准确获取炼焦煤热解过程中的动态信息，从“过程”角度关联煤质评价指标与焦炭质量指标；探究高硫煤配煤炼焦过程中煤种间的相互作用及其对配煤成焦和硫分变迁的影响，揭示抑制挥发分传质引起活性硫与新生半焦表面反应的有效途径；探究焦炭的反应性与其结构特征的内在关联。建立更为科学的炼焦煤特性评价体系，实现高硫焦煤配煤炼焦过程中硫分的定向调控，确定评价焦炭合理高效多元化利用的方法，为促进山西焦化企业的转型发展，提供基础理论指导和技术支撑。

In order to break through the pressing situations of the shortage of high quality coking coal, severe overcapacity and simple structure of coke production and limited extension of industrial chain, it is very important and has good application prospects to decrease coking cost and increase efficiency through improving the efficient utilization of high-sulfur coking coal and to promote the transformation and development of coking enterprises through adjusting the product structure and extending the production chain by producing gasification coke and domestic clean coke. Based on our previous work of the selective cleavage of C-S bond and in-situ hydrogen donation by active radicals from volatile matters, and using the synchrotron pyrolysis/coking systems and step-size coke test ovens, this project strives to investigate the underlying dynamic information during blended coal coking process and correlate the indices between coal properties and coke quality; to study the effects of interactions among different coking coals on coking ability and sulfur transformation behavior during blend coking of high sulfur coal, revealing the effective approach to restrict the surface interactions among active sulfur radicals and nascent coke; to investigate the inherent relationship between coke structure and reactivity. The outcomes of this project will establish a more scientific evaluation system of coal properties for coking, implement the directional regulation of sulfur during blend coking of high sulfur coal and determine the approaches of effective and diversified utilization of coke, which provide a fundamental theoretical guidance and technical support for the transformation and development of coking industry in Shanxi province.
