Hybrid approaches for capture and catalytic recycling of carbon dioxide

二氧化碳被认为是全球气候变化的主要原因。所有人为CO2排放量中约有三分之一来自用于发电的化石燃料。此外，各种工业过程（炼油厂，水泥厂，钢铁部门和铝生产）每年向大气中排放大量的二氧化碳。在加拿大，CEPA（加拿大环境保护法）是推动公司减少温室气体排放的立法机构。CO2捕获和封存的概念最近在CO2减排方面引起了相当大的兴趣。CO2捕集的目的是从不同的气体混合物中分离出纯气体，以产生浓缩的气流，供封存或进一步使用。一个非常有趣和有效的替代CO2封存的化学回收是二氧化碳转化为有价值的产品，如二甲醚（DME）。

CO2 is considered to have a major contribution to the global climate change. About one third of all anthropogenic CO2 emissions come from fossil fuels used for energy generation. In addition, various industrial processes (oil refineries, cement works, iron & steel sector and aluminum production) annually emit huge amounts of CO2 into the atmosphere. In Canada, CEPA (Canadian Environmental Protection Act) is the legislative authority that pushes the companies to reduce their greenhouse gas production. The concept of CO2 capture and sequestration has recently attracted a considerable interest in the CO2 emissions reduction. The aim of CO2 capture is to separate the pure gas from different gaseous mixtures in order to produce a concentrated stream ready for sequestration or further use. A very interesting and efficient alternative to CO2 sequestration by chemical recycling is the carbon dioxide conversion into valuable products like dimethyl ether (DME).
