Mathematical Modeling of Heat and Mass Transfer in the Drying of Granules Used as a Support for a Nickel Catalyst

“…The equation for the sorption polytherm obtained by experimental data processing (5) The equations of state for the vapor and gas components (6) Fick's diffusion law (7) Darcy's law (8) Dalton's law for calculating the intensity of phase transitions (9) Antoine's equation for determining the saturated vapor pressure at a given temperature (10) The initial and boundary conditions (11) (12) It should be noted that the important feature of the model is the application of original formulas for calculating time-varying local diffusion coefficients for a liquid a m and the values of phase transition criterion ε in Eqs. ( 1) and ( 2).…”

“…The objective of this study is to investigate the development of non-steady-state fields for moisture content, temperature, and pressure of a vapor-gas phase as a function of the parameters of a drying agent in order to determine the most effective operating conditions for the convective drying of the chosen support. Predicting the result of heat treatment of the moist granules of a support, which makes it possible to assess the reliability of a chemical process, has been performed using mathematical modeling techniques and principles [4,5].…”
