  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)
