Özet
Propagation dynamics of mass fronts in two different chemical processes: adsorption with first-order reaction in the fluid phase and exsorption (simultaneous extraction and sorption) with lean gas is described by a common partial differential equation. Mathematically, the common partial differential equation describes fixed-bed adsorption with first-order loss to fluid phase. The general analytical solution to this partial differential equation is adopted from the literature. The solution can be obtained via the method-of-characteristics technique after making local sorption-equilibrium approximation. Starting with this general analytical solution, particular analytical solutions for various types of adsorption isotherms are obtained. The effects of concentration dependence of different adsorption isotherms, loss-term coefficient, and magnitude of feed concentration on propagation dynamics of mass fronts are presented.
