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
