Preparation of an Anodic Alumina-Supported Ni Catalyst and Development of a Catalytic Plate Reformer for the Steam Reforming of Methane

A plate-type Al/Fe–Cr alloy/Al-clad substrate was used to prepare a sandwich-structured anodic alumina catalyst by anodization, post-modification treatment, and metal loading. The as-prepared utilized in the design of catalytic plate reactor for methane steam reforming reaction, 3D model developed simulate performance tube-type box-type reformers. experimental results preparation clad materials showed that hydrothermal treatment subsequent high-temperature calcination transformed amorphous skeletal conventional layer into γ-alumina, significantly increased its specific surface area. Simulation temperature difference between channel wall center gas phase thin-walled only 30% particulate catalyst, indicating potential advantages terms heat transfer energy saving. When length-to-diameter ratio (or length-to-width ratio) reaction is small height large, insufficient transverse mass backmixing are two major factors affecting reformer performance. For channels, 10~35, diameter 5~20 represent favorable choices. In contrast, channel, should be set 2~4 2~5 mm, respectively. Additionally, number inlet ports has significant effect on performance, distribution state provided close ideal state.
