摘要
在高温条件下将重整催化剂在高纯氧气流中氧化为二氧化硫,采用高精度的二氧化硫选择性非色散红外检测器测量二氧化硫的浓度。在优化条件下,用该方法测定重整催化剂中含量的检出限范围变大,精密度和准确度提高。该方法灵敏度高,测定结果准确可靠,可广泛应用于重整催化剂中硫含量的测定。
Under the condition of high temperature reforming catalystin is oxidized to sulfur dioxide at high oxygen and the concentration of sulfur dioxide was determined with selective high precision non-dispersive infrared detector Under optimized conditions, detection limit range is increased, accuracy and precision is improved. The method is sensitive, accurate and reliable and can be widely applied to the determination for sulfur content of reforming catalyst.
