一氧化碳、甲烷、二氧化碳是高纯气体产品中普遍控制的杂质，通常采用气相色谱法进行测定。使用热传导鉴定器、氦离子化鉴定器、质谱鉴定器、氧化锆鉴定器等均可给出良好的测定结果，但是，目前常用、经济的，应属火焰离子化鉴定器。

二氧化碳甲烷化技术不但在碳资源的循环利用和环境保护方面具有十分积极的意义,而且在其他许多方面具有重要的实际应用价值,如在制备氨、合成气和纯氢过程中少量CO2和CO的脱除；潜水艇、航天器舱室内二氧化碳的去除和氧气再生；气相色谱法分析中检测符合国家标准的高纯性气体以及研究植物光合作用等；尤其在焦炉气、褐煤合成代用天然气方面,受到学术界和产业界的高度关注,成为煤化工发展的重要方向。与一氧化碳相比,二氧化碳甲烷化反应具有较低的活化能,较低的反应温度及较高的选择性,同时在热力学和动力学上要比其他CO2催化加氢反应更加有利,由于反应体系简单也常作为理论研究加氢催化剂的探针反应。实现CO2甲烷化反应的核心是催化剂,在二氧化碳甲烷化催化剂体系中,镍基催化剂价格相对低廉,来源广泛,且活性较高,选择性好,得到人们广泛研究。

Application of methane reformer on Agilent 7890B
Application of methane reformer on Agilent 7890B Details:

Carbon monoxide, methane, and carbon dioxide are generally controlled impurities in high-purity gas products, and they are usually determined by gas chromatography. The use of heat conduction identifiers, helium ionization identifiers, mass spectrometry identifiers, zirconia identifiers, etc. can give good measurement results. However, the most commonly used and most economical at present should be the flame ionization identifier.

Carbon dioxide methanation technology not only has a very positive significance in the recycling of carbon resources and environmental protection, but also has important practical application value in many other aspects, such as the production of a small amount of CO2 and CO in the process of preparing ammonia, synthesis gas and pure hydrogen. Removal; carbon dioxide removal and oxygen regeneration in submarines and spacecraft cabins; detection of high-purity permanent gases that meet national standards in gas chromatography analysis; research on plant photosynthesis, etc.; especially in coke oven gas, lignite synthetic substitute natural gas , Has received great attention from the academic and industrial circles, and has become an important direction for the development of coal chemical industry. Compared with carbon monoxide, carbon dioxide methanation reaction has lower activation energy, lower reaction temperature and higher selectivity. At the same time, it is more advantageous than other CO2 catalytic hydrogenation reactions in terms of thermodynamics and kinetics, due to the simple reaction system It is also often used as a probe reaction for theoretical research on hydrogenation catalysts. The core of the CO2 methanation reaction is the catalyst. In the carbon dioxide methanation catalyst system, the nickel-based catalyst is relatively inexpensive, has a wide range of sources, and has high activity and good selectivity. It has been widely studied.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. developed the 2021 new HH-CH4-GC portable methane converter successfully combined with Agilent 7890B gas chromatograph to determine trace carbon monoxide and carbon dioxide, with high column efficiency, good separation, and satisfactory results.
