Development of System for Fixation and Capture of Carbon Dioxide

保护全球环境是21世纪最受关注的问题。高效地固定和捕获温室效应气体，特别是二氧化碳，可能是21世纪保护全球变暖和可持续发展的重要技术之一。我们开发了一种新的气体吸收捕集二氧化碳的方法，即利用沸石细颗粒形成雾状的冷凝膜法。本研究针对燃煤电厂、炼钢厂、水泥厂等作为二氧化碳集中固定源的电厂，提出了一种沸石细颗粒凝结水与二氧化碳气体固定的新方法。利用化学反应热，将含二氧化碳气体的凝结水经济地固化在碳酸钙生态块中，并通过实验明确了生态块在海水中的特性和有效性，以利用鱼滩。对垂直冷却管内的冷凝速率和气体吸收率进行了包括沸石雾形成速率在内的验证实验。并以某燃煤电站的排放数据为基础，对CO2捕集率和效率进行了仿真分析。

Protection of global environment is the gravest concern in the 21st century. High efficiency of fixation and capture of the greenhouse effect gas, especially Carbon Dioxide may be one of the important techniques for the protection of global warming and the sustainable development in the 21st century. We have developed a new capture method for Carbon Dioxide by gas absorption, that is the condensate film method by utilizing Zeolite fine particles with mist formation.In present research, a new fixation method for the condensate including Zeolite fine particles with Carbon Dioxide gas was proposed for aimed the power station with using coal fuel, the steelworks and/or the cement plant as a concentrated and fixed CO2 generation source. The condensate including Carbon Dioxide gas was solidified in eco-block of CaCO3 economically by utilizing the chemical reaction heat, and the characteristics and effectiveness of eco-block in seawater was experimentally clarified to make use of fishing banks.Its proof experiment was conducted with regard to the condensation rate and gas absorption rates in vertical cooling tube including Zeolite mist formation rate. And the simulation analyses were performed on the CO2 capture rate and efficiency on the basis of exhaust gas data from the coal fuel power station.
