GB/T 31196-2014

This standard specifies the laboratory test method for evaluating the catalytic activity of sulfur exhaust hydrogenation catalysts, which are used to convert residual sulfur compounds in tail gas from sulfur recovery units. It is applied in the chemical and petrochemical industries, particularly for quality control and performance assessment of catalysts used in Claus process tail gas treatment. The method provides a standardized procedure for comparing catalyst activity under controlled conditions, ensuring consistent performance in industrial desulfurization applications.
