Porous reactor
WebFeb 2, 2024 · This manuscript presents a simplified method of modeling fixed-bed reactors based on the porous medium. The proposed method primarily allows the necessity of precisely mapping the internal structure of the bed—which usually is done using real object imaging techniques (like X-ray tomography) or numerical methods (like discrete element … WebAn important class of reactors found in the solution mining, geothermal, and petroleum industries are porous dissolution reactors. These reactors are analogous to chromatographic reactors except that parts of the porous media are dissolved by the reacting fluid flowing through it. Single and multiple reaction fronts can develop in the …
