MAR2PROTECT Biomass-derived Carbons for the Separation of Fluorinated Gases DATASET

Fluorinated gases (F-gases) are widely used in the refrigeration industry and air conditioning equipment, being used as substitutes for ozone-depleting substances, since these compounds do not damage the atmospheric ozone layer, are non-toxic, and are not flammable. However, F-gases have high global warming potential, up to 23 000 times greater than carbon dioxide, and their atmospheric lifetime is up to 50 000 years. Then, small atmospheric concentrations of these gases can have large effects on global temperatures and on climate change. Hence, different legislations aim to combat their effect on the atmosphere, such as the EU regulation (No 517/2014) that targets to cut the emissions of these gases by 2/3 by 2030, compared to the levels of 2014. The aim of this work is to design, test, and validate climate-friendly processes, based on different Key Enabling Technologies (KETs), to separate and recover F-gases. These KETs are based on more efficient treatment systems, designed according to the principles of green chemistry, for the separation of the F-gases most used in air conditioning, commercial refrigeration, electrical circuit industry, thermal insulators, and electronic semiconductors at European level: R-134a - 1,1,1,2-tetrafluoroethane, R-32 – difluoromethane, R-125 – pentafluoroethane, SF6 – sulfur hexafluoride ) and nitrogen (N2). In this work, the adsorption of these gases was studied on 4 different biocarbons (CC-1:3H3PO4, CC-1:1H3PO4, CC-K2CO3 and CC-CO2). Then, this work contributes to reduce the environmental impact of these powerful greenhouse gases, answering one of the greatest current concerns of society, the environment, one central goal of EU Research.氟化气体（Fluorinated gases, F-gases）广泛应用于制冷行业与空调设备中，作为消耗臭氧层物质的替代品，因为此类化合物不会破坏大气臭氧层、无毒且不易燃。然而，氟化气体具有极高的全球变暖潜能，最高可达二氧化碳的23000倍，且其大气寿命长达50000年。因此，即使大气中此类气体的浓度较低，也会对全球气温及气候变化产生显著影响。 为此，多项立法旨在遏制其对大气的负面影响，例如欧盟第517/2014号法规，其目标是到2030年将此类气体的排放量较2014年水平削减三分之二。 本研究旨在基于多种关键使能技术（Key Enabling Technologies, KETs），设计、测试并验证气候友好型工艺，以实现氟化气体的分离与回收。这些关键使能技术依托遵循绿色化学原则构建的高效处理系统，用于分离欧洲地区空调、商用制冷、电路行业、热绝缘体及电子半导体领域最常用的氟化气体：R-134a（1,1,1,2-四氟乙烷）、R-32（二氟甲烷）、R-125（五氟乙烷）、SF6（六氟化硫）以及氮气（N2）。 本研究针对上述气体在4种不同生物炭（CC-1:3H3PO4、CC-1:1H3PO4、CC-K2CO3及CC-CO2）上的吸附行为展开了研究。本研究有助于降低这类强效温室气体的环境影响，回应了当前社会与环境领域最受关注的议题之一，同时契合欧盟研究的核心目标之一。
