Abstract
Description
本發明係關於二氧化碳淨化裝置,尤指一種能對低濃度的二氧化碳氣體進行光分解機制,以將二氧化碳轉化為可供後續利用之產物氣體的二氧化碳淨化裝置。The present invention relates to a carbon dioxide purification device, and more particularly to a carbon dioxide purification device capable of performing a photolysis mechanism on low-concentration carbon dioxide gas to convert carbon dioxide into product gas that can be subsequently utilized.
按,氣候變遷所造成的危機,一直是各國密切注意以及急欲解決的重大議題之一,隨著工業化的高速發展以及電力的需求上升,工廠、車輛甚至是火力發電廠等,都會產生大量的溫室氣體(如:二氧化碳),前述溫室氣體會攫住原應散發到太空中的熱量,使得原來的溫室效應更加強化,導致了地球平均溫度的上升,進而影響了氣候與環境(例如,沙漠化、改變降雨量等)。The crisis caused by climate change has always been one of the major issues that all countries have paid close attention to and are eager to resolve. With the rapid development of industrialization and the increase in demand for electricity, factories, vehicles and even thermal power plants will produce a large amount of greenhouse gases (such as carbon dioxide). The aforementioned greenhouse gases will capture the heat that should have been dissipated into space, making the original greenhouse effect more enhanced, leading to an increase in the average temperature of the earth, which in turn affects the climate and environment (for example, desertification, changes in rainfall, etc.).
承上,目前自大氣中去除或降低溫室氣體的方法,大致如下: (1) 物理變化:透過凝結或降雨的方式,以消除大氣中的水蒸氣; (2) 大氣中的化學反應:透過天然存在的羥自由基(·OH)與甲烷氧化反應,以降解為二氧化碳與水蒸氣; (3) 大氣與地球的部分組成間的物理作用:大氣中的溫室氣體混合至海洋中; (4) 大氣地球的部分組成間的化學作用:二氧化碳透過植物的光合作用,而形成氧氣; (5) 光化學變化(photochemical change)。 As mentioned above, the current methods of removing or reducing greenhouse gases from the atmosphere are roughly as follows: (1) Physical changes: removing water vapor from the atmosphere through condensation or rainfall; (2) Chemical reactions in the atmosphere: degrading into carbon dioxide and water vapor through the oxidation reaction of naturally occurring hydroxyl radicals (·OH) and methane; (3) Physical interactions between the atmosphere and some components of the earth: greenhouse gases in the atmosphere are mixed into the ocean; (4) Chemical interactions between some components of the atmosphere and the earth: carbon dioxide is converted into oxygen through photosynthesis of plants; (5) Photochemical changes.
然而,藉由自然界的作用去除或降低溫室氣體,顯然趕不上人為增加溫室氣體的速度,研究指出截至 2021 年為止,地球的大氣中,二氧化碳濃度比工業化前水平高出近50%。有鑑於此,部分業者開始嘗試利用二氧化碳來產生其他產物,藉此達到降低二氧化碳濃度的效果,同時還能得到足以作為它用(如:燃料)的其他產物。舉例而言,中國第CN113797866號專利案,係公開了一種無揮發性有機物(VOC)排放的內循環式有機合成反應櫃,其係能夠對VOC進行吸附和降解,以得到降解氣體,其中,前述降解氣體包含較多的二氧化碳,之後,將降解氣體通入二氧化碳濃縮器分離濃縮,以形成濃縮氣體,再將前述濃縮氣體通入二氧化碳電催化反應器中進行電還原反應,最終生成甲醇與甲酸。或者,中國第101428223號專利案,其能夠將二氧化碳水溶液進行光催化還原,以形成甲酸、甲醛與氫氣。However, the removal or reduction of greenhouse gases by natural processes cannot keep up with the rate of man-made greenhouse gas increases. Studies have shown that as of 2021, the concentration of carbon dioxide in the Earth's atmosphere is nearly 50% higher than the pre-industrial level. In view of this, some companies have begun to try to use carbon dioxide to produce other products, thereby achieving the effect of reducing carbon dioxide concentrations, while also obtaining other products that can be used for other purposes (such as fuel). For example, Chinese Patent No. CN113797866 discloses an internal circulation organic synthesis reactor without volatile organic compounds (VOC) emission, which can adsorb and degrade VOC to obtain degraded gas, wherein the degraded gas contains more carbon dioxide, and then the degraded gas is passed into a carbon dioxide concentrator for separation and concentration to form concentrated gas, and then the concentrated gas is passed into a carbon dioxide electrocatalytic reactor for electroreduction reaction to finally generate methanol and formic acid. Alternatively, Chinese Patent No. 101428223 can photocatalytically reduce a carbon dioxide aqueous solution to form formic acid, formaldehyde and hydrogen.
惟,現有以物理方式(如:活性碳、沸石、金屬氧化物或金屬碳化物等)或化學方式(如:氨水、碳酸鹽溶液、鹼金屬溶液等)處理二氧化碳的技術,大多是針對工廠廢氣中的高濃度二氧化碳(二氧化碳約佔氣體體積3%含量以上),但是,前述方式並不適合用於僅有低濃度二氧化碳的一般大氣(二氧化碳約佔一般大氣體積之350至450ppm)或其他氣體源,因此,如何有效解決前述問題,即為本發明之相關業者的重要課題。However, the existing technologies for treating carbon dioxide by physical means (such as activated carbon, zeolite, metal oxides or metal carbides, etc.) or chemical means (such as ammonia water, carbonate solution, alkaline metal solution, etc.) are mostly aimed at high-concentration carbon dioxide in factory exhaust gas (carbon dioxide accounts for about 3% or more of the gas volume). However, the above methods are not suitable for general atmosphere with only low concentration of carbon dioxide (carbon dioxide accounts for about 350 to 450 ppm of the general atmosphere volume) or other gas sources. Therefore, how to effectively solve the above problems is an important issue for the relevant industry of the present invention.
有鑑於前述習知的問題,申請人秉持精益求精的研究精神,在經過長久的努力研究與實驗後,終於研發出本發明之一種二氧化碳淨化系統,其中,光分解的機制係光照射至光觸媒組合物,透過光觸媒組合物催化產生電子或電洞激化,進而達到分解二氧化碳的功能。In view of the above-mentioned known problems, the applicant has adhered to the spirit of continuous improvement in research and, after long-term research and experiments, finally developed a carbon dioxide purification system of the present invention, in which the mechanism of photodecomposition is that light irradiates the photocatalyst composition, and the photocatalyst composition catalyzes the generation of electrons or holes to be excited, thereby achieving the function of decomposing carbon dioxide.
