在石油化工和催化反應(yīng)中，低碳烴中一氧化碳、二氧化碳(CO、CO₂)的分析經(jīng)常被人們所關(guān)注，它直接反映烴被氧化的程度，無論為了提高反應(yīng)產(chǎn)率、計(jì)算選擇性，還是進(jìn)行物料恒算，都必須準(zhǔn)確計(jì)量CO、CO₂。要從大量烴中檢測出微量的CO、CO₂(＞幾十ppm)，可以采用氣相色譜多柱切換系統(tǒng)，排除烴、氧的干擾，在通用的熱導(dǎo)池檢測器(TCD)上檢測。若要從大量烴中檢測出痕量的CO、CO₂(＜幾十個ppm-ppb>，則需將已分離的CO、CO₂分別轉(zhuǎn)化為甲烷和水，在高靈敏度的氫火焰檢測器(FID)上檢測。

工業(yè)上檢測低碳烴中痕量CO、CO₂成熟的流程是日本島津公司的GC-S161乙烯、丙烯中微量CO、CO₂分析系統(tǒng)，基于FID的氣相色譜GC-14BPF，采用4個閥、14根色譜柱、2個轉(zhuǎn)化器和2個FID檢測器聯(lián)用的雙流路流程，調(diào)試十分復(fù)雜。不僅阻力很難匹配，而且常常不知道CO、CO₂在哪根柱子，以很難調(diào)試。

滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，根據(jù)安捷倫氣相色譜儀的特點(diǎn)，量身定制的甲烷轉(zhuǎn)化爐，效率高，體積小，安裝簡單方便，實(shí)用性強(qiáng)，一般實(shí)驗(yàn)室人員即可完成安裝，出峰快，峰型對稱，CO，甲烷和二氧化碳得到分析分離，結(jié)果準(zhǔn)確。

Methane reformer for Agilent gas chromatograph
Methane reformer for Agilent gas chromatograph Details:

In petrochemical and catalytic reactions, the analysis of carbon monoxide and carbon dioxide (CO, CO2) in low-carbon hydrocarbons is often paid attention to. It directly reflects the degree of hydrocarbon oxidation, whether it is to increase the reaction yield, calculate the selectivity, or perform For constant calculation of materials, CO and CO2 must be accurately measured. To detect trace amounts of CO and CO2 (> tens of ppm) from a large amount of hydrocarbons, a gas chromatographic multi-column switching system can be used to eliminate the interference of hydrocarbons and oxygen and detect on a general thermal conductivity cell detector (TCD). To detect trace amounts of CO and CO2 (< dozens of ppm-ppb> from a large amount of hydrocarbons), the separated CO and CO2 must be converted into methane and water respectively. The high-sensitivity hydrogen flame detector (FID ) On the test.

The industrially mature process for detecting trace CO and CO2 in low-carbon hydrocarbons is the GC-S161 ethylene and propylene trace CO and CO2 analysis system of Shimadzu Corporation of Japan, and the gas chromatography GC-14BPF based on FID, which uses 4 valves, 14 The dual-flow process (see Figure 1) with a chromatographic column, 2 converters and 2 FID detectors combined is very complicated. Not only is it difficult to match the resistance, but it is also difficult to debug which column the CO and CO2 are.



Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., according to the characteristics of Agilent gas chromatograph, tailor-made methane converter, high efficiency, small size, simple and convenient installation, and strong practicability. General laboratory personnel can complete the installation. The peak is fast, the peak shape is symmetrical, CO, methane and carbon dioxide are analyzed and separated, and the results are accurate and reliable.
