Porous reactor
WebWhen porous Ni-Cr plate was used, gradual oxidation of the catalyst occurred due to the air purging of the reactor in shut-down process, leading to degradation of the reactor performance. Compared with Ni-Cr catalyst, Ni-Al alloy had higher oxidation resistance and comparable activity toward methane and propane reforming. 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 …
