Appendix

Test Method for Equilibrium Moisture of Coke

1. Scope

The document herein (the "Document") stipulates the test method for equilibrium moisture of coke.

The document applies to metallurgical coke.

2. Cited rules and standards

The contents of the following documents constitute indispensable provisions of the Document through normative references within the text. For dated referenced documents, only the version corresponding to that date shall be applied to the Document; for undated referenced documents, the latest versions (including all the amendments) shall be applied to the Document.

GB/T 1997 Coke-sampling and Preparation of Samples

GB/T 2001 Coke-Determination of Proximate Analysis

3. Summary of the Method

After coke reaches saturated water absorption, it is dried at a temperature of (60±5) °C under standard atmospheric pressure for 4 hours. A specified mass of the dried coke sample is then weighed and dried to constant mass in an air stream at a temperature of (175±5) °C. The equilibrium moisture is calculated based on the mass loss of the sample after drying.

4. Experimental Instruments, Equipment, and Materials

4.1 Drying Oven

Equipped with automatic temperature control and blast device, capable of maintaining temperatures within the range of (60±5) °C and (175±5) °C, featuring gas inlet/outlet ports and sufficient ventilation volume, and capable of performing air exchange at least 5 times per hour

4.2 Industrial Balance

Sensitivity: 0.1 g

4.3 Shallow Tray

Made of heat-resistant and corrosion-resistant materials such as enamel, stainless steel, galvanized iron, or aluminum, with capacity capable of holding 500g of the sample, and the load per unit area not exceeding 1g/cm³

5. Experimental Procedures for Equilibrium Moisture

5.1 Collect a coke sample of no less than 5kg pursuant to the specifications in GB/T 1997. Immerse the entire coke in water and let it stand for 24 hours. Take out the coke and drain for 1 minute through a wire mesh basket.

5.2 Place the drained sample into a shallow tray and transfer to a drying oven that is pre-blasted and preheated to (60±5) °C. Dry the sample under air-blast condition for 4 hours.

5.3 Take out the dried coke sample and prepare a test sample of less than 13 mm pursuant to the specifications in GB/T 1997. Quickly weigh (500±10) g (accurate to 0.1 g) of the 13 mm sample in a pre-dried and weighed shallow tray and spread it evenly in the shallow tray.

5.4 Place the shallow tray containing the sample in a drying oven that has been pre-blasted and preheated to (175±5)°C. Dry the sample under air-blast condition for 1 hour.

5.5 Remove the tray, cool for 5 minutes, and weigh the sample accurate to 0.1 g.

5.6 Conduct inspection drying for 10 minutes each time until the difference in mass between two consecutive samples does not exceed 1g or the mass increases. Use the final mass for calculation. If there is a weight increase, the mass before the weight increase shall be used as the basis for calculation.

6. Calculation Results

6.1 Equilibrium moisture shall be calculated using formula (1):

·····················(1)

Where:

Mf means the equilibrium moisture of the coke, %;

m means the mass of the sample, in grams (g);

m1 means the mass of the sample after drying, in grams (g).

6.2 The test result shall be the arithmetic mean of the two test results.

6.3 Precision: The repeatability and reproducibility of equilibrium moisture determination shall not exceed the values specified in Table 1.
