聚丙烯裝置生產(chǎn)中對丙烯原料中一氧化碳、二氧化碳含量控制較為嚴格,特別是使用茂金屬催化劑后,對丙烯中的一氧化碳、二氧化碳含量要求提升到uL/m~3級,而目前所用的分析方法GB/T 3394-2009《工業(yè)用乙烯、丙烯中微量一氧化碳、二氧化碳和乙炔的測定氣相色譜法》最低檢出限只能達到mL/m~3級,完全不能適應目前更高的要求;
浩瀚色譜（山東）應用技術(shù)開發(fā)有限公司通過對分析方法實驗條件的改造優(yōu)化,以及試驗摸索,建立了可檢測丙烯中微量一氧化碳、二氧化碳分析方法,結(jié)果表明:經(jīng)優(yōu)化后的方法測定丙烯中一氧化碳與二氧化碳最低檢出限分別可達5uL/m~3與18uL/m~3,方法3次重復測定被測組分的相對標準偏差均小于12.85%,數(shù)據(jù)的精密度良好,可滿足聚丙烯裝置試用茂金屬催化劑對丙烯檢測的技術(shù)要求。

The content of carbon monoxide and carbon dioxide in propylene feedstock is strictly controlled in the production of polypropylene plant, especially after the use of metallocene catalyst, the requirement for carbon monoxide and carbon dioxide in propylene is raised to the level of uL/m~3, while the minimum detection limit of the currently used analytical method GB/T 3394-2009 "Determination of trace carbon monoxide, carbon dioxide and acetylene in ethylene and propylene for industrial use by gas chromatography" can only reach the level of mL/m~3, It is completely unable to meet the current higher requirements;
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established an analytical method that can detect trace carbon monoxide and carbon dioxide in propylene through the transformation and optimization of the experimental conditions of the analytical method and experimental exploration. The results show that the minimum detection limit of carbon monoxide and carbon dioxide in propylene can reach 5uL/m3 and 18uL/m3 respectively by the optimized method, and the relative standard deviation of the three repeated determinations of the tested components is less than 12.85%, The precision of the data is good, which can meet the technical requirements for propylene detection by using metallocene catalyst in polypropylene plant.
The conversion efficiency of HH-790CH4-GC methane conversion furnace is gao, which is simple to install, portable, small and exquisite, and integrates heating, gas path, sample injection, temperature control, and column separation system; It can be extended to 2D/multi-dimension, blowback and cutting systems.
