This dataset contains data and MATLAB scripts that are required for description of thermodynamic functions of 46 zeolites using Einstein-Planck functions sum and CpFit program developed in Laboratory of Chemical Thermodynamics, Lomonosov Moscow State University, Russia. Folders contents: 1) cpfit_data -- Database files for CpFit program. Contains experimental data points taken from literature, virtual points, parameters optimization settings and optimized parameters of thermodynamic models. 2) matlab -- Additive model MATLAB scripts. Contains implementation of the additive composition dependent model, i.e. scripts for generation of input datasets, optimization of model parameters and calculations using optimized model parameters. 3) tables -- Tabulated thermodynamic for zeolites. All values of Cp, S and H are in J/(mol*K), J/(mol*K) and J/mol respectively.
