增碳剂硫含量检测方法的对比分析

Comparison and Analysis of Test Methods for Sulfur Content of Carburetant

介绍了增碳剂硫含量检测的标准方法，简述了艾氏卡法、高温燃烧法和库仑法的测试原理和优缺点，用不同方法测试并对比了石墨、无烟煤和焦炭标样的硫含量。验证结果表明，艾氏卡法准确度高、重复性好，而高温燃烧法和库仑法操作便捷，适用于日常大批量增碳剂硫含量的分析。

The standard test methods for sulfur content of carburetant were introduced, and the testing principle of Eschka method, high temperature combustion method and Kulun method and their advantages and disadvantages were described briefly. The standard samples, such as graphite, anthracite coal and coke were tested and compared by different methods. The results show that the Eschka method has high accuracy and good repeatability, and the high temperature combustion method and Kulun method with convenient operation are suitable for sulfur content of mass carburetant in daily testing.
