Titanium dioxide type sulfur recovery catalyst
Physical properties test methods
1 Scope
This standard specifies the tight bulk density, particle radial crush resistance, wear rate, and specific surface area of titanium dioxide-based sulfur recovery catalysts.
Determination of pore volume and average pore radius.
This standard applies to the Claus sulfur recovery process with hydrogen sulfide acid gas as the raw material, and sulfur dioxide with titanium dioxide as the main active component.
Catalyst.

3 samples
3.1 Laboratory samples
Acquired according to the provisions of GB/T 6678.
3.2 Samples
Take an appropriate amount of laboratory sample and use a test sieve with an aperture of φ2.0mm (according to R40/3 series in GB/T 6003.1) to remove dust and debris.
Grain, ready for use.
4 Determination of tight bulk density
4.1 Stacking of Samples
Place an appropriate amount of sample in an electric blast oven, dry at 120°C±5°C for 2 hours, and then place in a desiccator to cool to room temperature.
Divide the sample into several parts, and add 1000mL graduated cylinders in order. After each addition, shake the cylinder up and down several times until the sample is in the cylinder.
The internal position does not change to vibration, and the operation is repeated until the amount of the tapped sample is 500 mL.
4.2 Weighing of Samples
The mass of the 1000 mL graduated cylinder, the mass of the 500 mL sample and the graduated cylinder were weighed to the nearest 0.1 g.
4.3 Calculation of Tight Density
The tight bulk density, ρ, is expressed in grams per milliliter (g/mL) and is calculated according to equation (1).
ρ=
M2-m1
