Kinetic and Thermodynamic Study of the Wet Desulfurization Reaction of ZnO Sorbents at High Temperatures

Hot gas conditioning is a remarkable stage for decreasing typical and harsh contaminants of syngas produced in the biomass gasification process. Downstream containing hydrogen sulphide (H2S) can significantly deteriorate fuel stream conversion reactors cell systems. Thus, an effective cleaning required to remove critical streams that endanger whole pathway toward In this work, we studied H2S capture from biofuel by using kinetic deactivation model analyze effect operating conditions on adsorption performance. Furthermore, particle sorbent influence other reactions, such as methane reforming water shift (WGS), were also evaluated. Breakthrough curves plotted fitted following first-order linearized perform both capacity thermodynamic analysis. Moreover, was through breakthrough curve simulation. By Arrhenius Eyring–Polanyi expressions, it possible calculate activation energy some parameters transition state theory. Finally, mathematical analysis performed obtain diffusion coefficient (D) reaction constant (k¯0) within ZnO particles, considering spherical geometry.
