【摘要】：CO_2是主要温室气体,其大量排放导致全球气候变暖,但同时也是一种重要的碳资源。我国工业化、城镇化的快速推进使得能源消耗日益上涨,如何使煤炭的高效清洁利用和减少CO_2排放已成为制约我国经济社会发展重要因素。若能将煤清洁高效转化与CO_2转化利用有效结合,实现碳资源的高效利用及碳循环,将具有非常重要的经济、社会和环境意义。本论文在分析CO_2排放现状与利用技术、煤气化技术理论及发展基础上,深入探讨用CO_2部分替代或者完全替代水蒸气作为气化剂的气流床粉煤加压煤气化理论,工艺技术以及工业应用的可行性和实践操作性。基于气流床粉煤加压气化技术,开展高浓度CO合成气制备技术及其中试装置的开发研究。对技术工艺进行设计与计算,对各单元工艺进行详细阐述,对主要设备进行了设计及计算,同时对工艺控制及联锁系统也进行了设计。气化装置设计投煤量10kg/h,设计温度1500℃,设计压力1.0MPa,完成了中试装置的建设,并对其运行作了预测。结合工艺、设备、控制方案的实用性及优化的可能性进行了评价和说明。该技术中试装置的开发为后续的工业化推进具有十分重要的推动作用。
[Abstract]:CO_2 is the main greenhouse gas, its emission causes global warming, but it is also an important carbon resource. With the rapid development of industrialization and urbanization in China, the energy consumption is increasing day by day. How to make the coal use efficiently and cleanly and reduce the CO_2 emission has become an important factor restricting the development of our country's economy and society. It will be of great economic, social and environmental significance if we can effectively combine clean and high efficiency coal conversion with CO_2 conversion, and realize the efficient utilization of carbon resources and carbon cycle. Based on the analysis of CO_2 emission status and utilization technology, coal gasification theory and development, this paper deeply discusses the theory of pressurized coal gasification with CO_2 partially replacing or completely replacing water vapor as gasification agent. Feasibility and practicability of process technology and industrial application. Based on the pressurized gasification of pulverized coal with airflow bed, the preparation technology of high concentration CO syngas and its pilot plant were developed. The technical process is designed and calculated, the process of each unit is described in detail, the main equipment is designed and calculated, and the process control and interlocking system is also designed. The pilot plant was constructed with 10 kg of coal per hour, design temperature of 1500 鈩，
