The purposes of this project were to do fundamental researches for supporting the development of (A) new coal pretreatment methods, (B) in situ de-Nox/de-Sox methods, and c enhanced flue gas treatment methods. The developed technologies are for the utilization of low rank coals in power generation in the near future. The project was revised and/or modified through the internal assessment and evaluation by the steering committee. Main results obtained are (A) the developments of new coal pretreatment methods utilizing solvents, various forms of CaO particles, (B) the proposal of a new fluidized bed coal combustion concept and the development of de-Nox/de-Sox methods utilizing a macro porous CaO, and c de-Nox/de-Sox methods at room temperature utilizing an activated carbon fiber and the development of several new types of de-Nox/de-Sox sorbents. Furthermore, several methods were proposed for the measurement and removal of trace elements such as Hg and As. These outcomes will be surely utilized in the coal utilization technologies in the near future.Endeavor was also made to make public the outcome of this project. The final report was prepared in English, and all the presentations at the review meeting were also made in English. Four distinct researchers from abroad made plenary lectures at the review meeting and a panel discussion was made on the future development of clean coal technology and international cooperation. In March of this year a symposium called "Clean Coal Technology" was organized by the head investigator at 225^<th> national meeting of the American Chemistry to advertise the results of this project. Furthermore, the publication of a special issue of one of internationally prestigious journals, FUEL, is now in progress to make public the outcome of the symposium. These activities will help the outcome of this project to be utilized world wide.

该项目的目的是进行基础研究，以支持（A）新的煤预处理方法，（B）原位脱氮/脱硫方法和c增强烟气处理方法的开发。所开发的技术是为了在不久的将来利用低阶煤发电。通过指导委员会的内部评估和评价，对该项目进行了修订和/或修改。所获得的主要结果是（A）利用溶剂、各种形式的CaO颗粒的新的煤预处理方法的开发，（B）新的流化床煤燃烧概念的提出和利用大孔CaO的脱NOx/脱Sox方法的开发，以及c在室温下利用活性碳纤维的脱NOx/脱Sox方法和几种新型脱NOx/脱Sox吸附剂的开发。此外，还提出了几种测定和去除汞和砷等微量元素的方法。这些成果必将在不久的将来应用于煤炭利用技术中。奋进也被要求公开该项目的成果。最后报告以英文编写，审查会议上的所有发言也以英文进行。来自国外的四位研究人员在审查会议上作了全体演讲，并就洁净煤技术的未来发展和国际合作进行了小组讨论。今年3月，在美国化学第225届全国会议上，首席研究员组织了一个名为“洁净煤技术”的研讨会<th>，以宣传该项目的成果。此外，目前正在出版一份国际著名期刊《燃料》的特刊，以公布专题讨论会的成果。这些活动将有助于该项目的成果在全世界得到利用。
