Granular activated carbon coal quality test methods for desulfurization and denitrification
Part 4. desulfurization value
1 Scope
GB/T 30202 provisions of this part of the measurement principle desulphurization and denitrification granular activated carbon from coal (hereinafter referred to as active coke) desulfurization value,
Procedures and results of calculation content determination.
This section applies to the determination of Activated Coke values.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Desulfurization value desulfurizationvalue
After Under certain conditions, the activity per unit mass of coke sulfur dioxide adsorption, desorption mass high-temperature sulfur dioxide.
3 Principle of Measurement
After pretreatment of the sample, the adsorption of sulfur dioxide, water vapor, oxygen and nitrogen mixed gas under certain conditions, when the sulfur dioxide absorption saturation
Attached, which leads to nitrogen desorption, based on the amount of sulfur dioxide desorbed calculated value desulfurization active coke.
