Thermodynamic and kinetic investigations of the SrBr2 hydration and dehydration reactions for thermochemical energy storage and heat transformation

Adsorption behavior of H2O on the strontium bromide surface: first-principles and molecular dynamics calculations

“…The relationship between different water vapor pressures and adsorption was investigated in laboratory tests. 36 Thus, we set the pressure range to 0–100 kPa. It can be seen that with the increase of the water vapor pressure, the adsorption amount augments rapidly and gradually approach to the equilibrium state.…”

Solar-thermal energy conversion prediction of building envelope using thermochemical sorbent based on established reaction kinetics

“…where (ρc)eff =(1−θ) (ρcp)s +θ (ρcp)a, and the effective thermal conductivity of the reactive bed λeff = (1−θ) λs + θ λa, where θ is the porosity, λs and λa are the thermal conductivity of the composite sorbent and air, respectively, and reac q is the reaction energy source [14]:…”

“…Many salt hydrates such as SrBr2•6H2O [14], CaCl2•2H2O [15], MgCl2•6H2O [16], K2CO3•1.5H2O [17], and MgSO4•7H2O [18] seem to provide attractive opportunities due to their theoretically high ESDs (1-3 GJ/m 3 ). However, their inherent drawbacks, e.g., the easy deliquescence of CaCl2 and the poor re-hydration ability of MgSO4 severely limit practical applications.…”

“…Because the tests are performed at the fixed temperature, the coefficient is constant and therefore, the dependence h(p) vs. k should be as linear as possible. This is the criterion for the choice of the power function, the general form of which is [14]:…”

Experimental and Numerical Validation of the One-Process Modeling Approach for the Hydration of K2CO3 Particles

“…Furthermore, the Arrhenius-f (α) model does not shed any light on the influence of morphologic variables, as these are lumped in the pre-exponential factor A. In the literature, a pressure ratio term is added to the Arrhenius-f (α) model to account for the anhydroushydrated equilibrium pressure, and the partial water vapor pressure [30,33,[36][37][38]. The pressure term is given by…”
