DDBSP: Vapor Phase Adsorption Package

This package contains both the DDB data bank for vapor phase adsorption data (DDB-ADS) as well as suitable software for storage, visualization, correlation, prediction, ... of both single and multi-component adsorption. The figure below shows a graphical representations of the adsorption isotherms of CO2 on silica gel at different temperatures:

 

For single component adsorption, the following models are included for single data set regression:

  • Freundlich-Isotherm
  • Langmuir-Isotherm
  • Brunauer-Emmett-Teller-Isotherm
  • Mixed-Langmuir-Freundlich-Isotherm
  • Toth-Isotherm
  • Statistical combined Langmuir-Isotherm
  • Modified Langmuir-Isotherm for SSTM
  • Virial-Isotherm-Equation (SPD)
  • Vacancy Solution Model
  • Dubinin-Astakhov-Isotherm for MI/RAST

Two different models allow the correlation of multicomponent adsorption:

  • Real Adsorbed Solution Theory
  • Modified Stat. Thermodyn. Model

In addition, several models are included for the prediction of multicomponent adsorption:

  • Ideal Adsorbed Solution Theory
  • Wilson - Vacancy Solution Model
  • F-H - Vacancy Solution Model
  • Multiphase IAST
  • Multiphase RAST
  • Predictive RAST
  • Vacancy Solution Model
  • Simplified Binary Model
