我国褐煤资源丰富，开发褐煤液化技术对我国的能源安全和褐煤资源的有效利用具有重要意义。本项目针对褐煤的工艺性质特点，在深入分析与充分认识以合成气作为氢源的含水褐煤液化化学过程的基础上，提出含水褐煤液化条件下CO与H2O和煤有机质的反应及其作用机制研究，凝练了与本项目技术开发关系十分密切的一个关键科学问题：本液化条件下CO发挥何种作用及怎样发挥作用等。为此，拟重点围绕以下三个方面的内容进行研究：本液化条件下CO与H2O发生变换反应产氢的机理；本液化条件下变换反应产生“氢”的活性及作用机制；本液化条件下CO与褐煤有机质结构的反应机理及其作用机制。这项研究有明显特色和创新性，不仅可深刻认识本液化条件下褐煤液化过程中CO的作用机制，丰富褐煤液化科学的有关内容，而且可为含水褐煤液化新工艺技术的进一步开发提供理论依据和重要数据。与本研究有关的前期工作为本项目顺利实施奠定了坚实基础。

Because of the abundance of lignite reserves in our country, developing liquefaction technologies is very significant for the energy security of our country and the efficient utilization of lignite resource. Based on deep considerations of the technical properties of lignite and the chemical processes of direct lignite liquefaction using syngas as hydrogen sources, the project proposed the study on the reactions of CO with H2O and coal organics and their action mechanisms during containing-water lignite liquefaction. Simultaneously, a key sientific problem which was closely related to the development of liquefaction technology, was proposed as follows: which roles can CO play under the liquefaction system? how does CO play the roles under the liquefaction system? Therefore, the main research contents are planned as follows: the production mechanisms of hydorgen from the shift reaction beween CO and H2O under the liquefaction conditons, the acitivities of produced hydrogen and its action mechanisms under the liquefaction conditons, and the reactions beween CO and coal organics and their action mechanisms under the liquefaction conditons . The study with distinctive characteristics and innovations not only can provide the deep understandings on the CO action mechanisms during the containing-water lignite liquefaction and enrich the relevant contents on the subject of lignite liquefaction, but also provide the theoretical basis and significant data for the further development of the containing-water lignite liquefaction technology under this system. The previously pertinent researches can make a firm foundation for the smooth implement of this project.
