ST-64B Activated carbon penetration sulfur capacity tester

ST-64B activated carbon penetration capacity testing device is developed in accordance with the national standard GB/T7702.14-2008 "Test methods for coal based granular activated carbon - Determination of sulfur capacity". It is suitable for testing the penetration capacity of coal based granular activated carbon, as well as for testing the penetration capacity of other types of activated carbon.

Experimental principle:

The test sample is burned in a purified air flow at a high temperature of 1050 ℃, and various forms of sulfur in the coal are decomposed and carried to the electrolysis cell by the air flow to combine with water to generate H2SO3. Due to its disruption of the dynamic equilibrium of the original iodine iodine ion pairs in the electrolysis cell, the instrument immediately outputs a current to electrolyze potassium iodide solution to generate iodine, in order to restore the original dynamic equilibrium, which is the Coulomb titration in GB/T214-1996. The amount of current consumed to restore the original dynamic equilibrium is related to the sulfur decomposed during combustion in the laboratory sample, which can be measured and calculated by a microprocessor
