HH-790CH4甲烷转化炉

甲烷化转化炉主要用于气相色谱分析气体样品中微量的一氧化碳、二氧化碳。如电力变压器油溶解气体分析；化肥合成氨生产中、高纯氢、高纯氮、高纯氧、高纯氦、高纯氩等气体中的一氧化碳、二氧化碳的杂质分析；还可用于空气分离产品离线检测、高纯气体厂家质量控制及其他用途等。
甲烷化转化炉采用高效镍催化剂，采用氢作载气或氮作载气柱后加氢的方式，把不能被氢火焰离子化检测器检测的微量CO和CO₂转化为CH₄。我公司自制的催化剂具有转化效率高，加热块死体积小，温场均匀，对分析各种高纯气体中微量CO、CH₄、CO₂具有非常高的检测灵敏度，最小检测浓度≤0.1ppm。

Methane conversion furnace is mainly used for gas chromatography analysis of gas samples of trace amounts of carbon monoxide, carbon dioxide. Such as power transformer oil dissolved gas analysis; chemical fertilizer ammonia production, high purity hydrogen, high purity nitrogen, high purity oxygen, high purity helium, high purity argon and other gases in carbon monoxide, carbon dioxide impurities; High purity gas manufacturers quality control and other uses.
Methane conversion furnace using high-efficiency nickel catalyst, hydrogen as carrier gas or nitrogen as carrier gas column after hydrogenation, can not be hydrogen flame ionization detector detection of trace CO and CO2 into CH4. Our homemade catalyst has high conversion efficiency, small dead volume and uniform temperature field. It has very high detection sensitivity for the analysis of trace CO, CH4 and CO2 in high purity gases. The minimum detection concentration is less than 0.1ppm.
