A study of the heat transfer characteristics of novel Ni‐foam structured catalysts
Tóm tắt
Highly exothermic reactions require catalyst beds with good heat transfer characteristics. Novel Ni‐foam structured catalysts have significant heat transfer efficiency compared with traditional packed beds, which is very suitable for the highly exothermic methanation reaction. The present work reports an experimental study of steady‐state heat transfer behaviour of a gas flowing through a fixed bed packed with Ni‐foam structured catalyst under various operation conditions. Experiments were carried out in a dedicated tubular reactor with inlet air temperature ranging from 160 to 200 °C, heating pipe temperature inside the fixed bed ranging from 400 to 500 °C, and air flow rate ranging from 4.0 to 6.0 Nm3/h. Effective radial conductivity (
