建立了采用高频红外碳硫仪测定流化床触体样品中碳含量的方法。通过向流化床触体样品中加入纯铁、锡粒和钨粒助熔剂，促进样品中的碳完全燃烧，采用高频红外碳硫仪测定燃烧生成的CO2的特征吸收峰的强度变化，通过朗伯-比尔定律间接测定样品中的碳含量。研究了样品用量、助熔剂的种类及用量对测试结果的影响。结果表明，在样品加入量为0．1 g、纯铁助熔剂0．2 g、锡助熔剂0．15 g、钨助熔剂1．5 g条件下，测试流化床4个床层高度触体样品的碳含量，测定结果的相对标准偏差均小于3%，加标回收率达到101．6%。该方法操作简单易行，适合于对流化床触体进行中控质量检测。

This paper describes a method for determining the content of carbon in fluidized bed tested by a high-frequency infrared carbon and sulfur analyzer. Results indicated that iron, tin or tungsten flux would promote the complete combustion of the sample, and the generated complete combustion of carbon. The high-frequency infrared carbon and sulfur analyzer measured the characteristic absorption peak intensity of carbon dioxide by Lambert-Beer law to give the carbon content of the sample. Experiments show that when the sample is added with 0. 1 g, iron flux 0. 2 g, tin flux 0. 15 g and tungsten flux at 1. 5 g, tested four RSDs of the sam-ple from different bed heights of the fluidized bed were less than 3%, spiked recovery rate of 101 . 6 %. The method is accurate and simple, suitable for ongoing quality control of silica fume in fluidized bed.
