Sample weight: no less than 2kg

Industrial analysis implements complied with GB/T2121991 of Coal

Sample Industrial Analysis Method

Air Tightness Inspection

Air inflation

Filling Helium to system, pressure is higher than the highest pressure 1MPa of Isothermal Adsorption Experiment. System temperature adjusted to the reservoir temperature. Continuous observation for the system seal condition, if it’s good, to the next experiment.

Free Space Volume Measurement

Temperature

System temperature is adjusted to reservoir temperature

Inflation

Open the cylinder; inflate the gas to system, adjust standard pressure valve, and then close the standard room valve

Data Acquisition

Open the valve of standard room and sample cylinder collect the data after the balance of pressure, do the volume experiment twice, allowable error is ±0.1cm³, calculate the coal volume and get the blank

Isothermal Adsorption Experiment

Experiment Pressure determination

The highest experimental pressure is set up to 1.2 times of reservoir pressure, minimum pressure is 8MPa

Experiment Pressure Spot Distribution

Highest Pressure<8MPa, choose 6 experiment spots; Highest Pressure between 8MPa-12MPa, choose 7 experiment spots; Highest Pressure <12MPa, choose 8 experiment spots

Inflation

Open regulated valve and standard room valve, inflate methane to system, and adjust the standard room pressure to ideal pressure.

Data acquisition

After get the ideal pressure and stable temperature, start the data collection of the isothermal adsorption experiment program

Time of Adsorption Balance Determination

No less than 12 hours at least

Repeating Step 3 -5, until the end of experiment of last pressure spot

Data Processing

The calculation of coal sample volume and free space volume

The design formulas of coal volume as follows:

VS- Coal sample volume, units of measurement (cm³);

P1- Balanced pressure, units of measurement (MPa);

P2- Initial pressure of reference cylinder, units of measurement (MPa);

P3- Initial pressure of sample cylinder, units of measurement (MPa);

T1- Balanced temperature, units of measurement (K);

T2- Initial temperature of reference cylinder, units of measurement (K);

T3- Initial temperature of sample cylinder units of measurement (K);

V1- System total volume units of measurement (cm³);

V2- Reference cylinder volume units of measurement (cm³);

V3- Sample cylinder volume units of measurement (cm³);

Z1- Gas compression factor under the balance condition, dimensionless

Z2- Initial gas compression factor of reference cylinder, dimensionless

Z3- Initial gas compression factor of sample cylinder, dimensionless

After getting the coal sample volume, calculate the free space volume of sample cylinder. Free Space Volume refers to the sum of various volumes that coal particle space after the coal sample put into the sample cylinder, micro-flow gap of internal coal particle size, the remaining free space of sample cylinder, and connection tube and internal space volume. Calculation formulas of free space volume as follows:

Vf- Free space volume, unit of measurement (cm³)

V0- Total volume of sample cylinder, unit of measurement (cm³);

Vs- Coal sample volume, unit of measurement (cm³);

Z3- sample cylinder initial gas compressed factor, dimensionless

Calculation the absorption capacity of each pressure spot

According to balance pressure and temperature of reference cylinder and sample cylinder, calculate adsorption capacity of different pressure spot Formulas as follows

PV=nZRT

P-Gas pressure, unit of measurement (MPa)

V- Gas volume, unit of measurement (cm³);

n- Gas mole number, unit of measurement (mol)

Z- Gas compressor factor, dimensionless

R- Molar gas constant, unit of measurement (U·mol-1·K-1)

T- Thermodynamic temperature unit of measurement (K)

Respectively obtain the gas mole number of inner sample cylinder before pressure spot balance and after balance, the gas mole number of sample cylinder (N2), mole number of coal sample adsorption of gas (ni)

Ni=n1-n2

ni- Gas mole number, unit of measurement (mol)

N1- Sample cylinder‘s gas mole quantity after balance, unit of measurement (mol).

N2- Sample cylinder‘s gas mole quantity after balance,, unit of measurement (mol).

Adsorption gas volume of each pressure spot

VI=ni * 22.4 * 1000

The gas volume of each pressure spot adsorption:

V adsorption=V i/ c

V-adsorption- Adsorption capacity, unit of measurement (cm³/g)

-total volume of adsorption gas, unit of measurement (cm³/g)

-coal sample weight, unit of measurement (g)
