催化剂颗粒形状对甲烷水蒸气重整反应的影响及工业反应器模拟

摘要

Methane steam reforming (MSR) is the most widely used technology for hydrogen production in industry now, where the shape of catalyst particles and the reactor operating conditions greatly influence the reactor performance and the product composition. Firstly, the present study investigated the effect of catalyst shape (sphere, cylinder and ring) on the MSR using a diffusion-reaction model on the particle scale. The effectiveness factors of shaped catalysts followed the sequence:cylinder
