Abstract

A novel microreactor with a structured catalyst was proposed. The structured catalyst has micro partition (MP), which functions as a catalyst support. The MP has fins on the plate with holes and consists of aluminum, and it was loaded into the tube. To demonstrate the influence of MP on reactivity, the methanol conversion for steam reforming was measured. First, the methanol conversion of the MP and MP with flatten fins on the surface (i.e., plate-like structure) catalysts were compared. The MP-structured catalyst demonstrated higher reactivity for methanol than the conventional plate-like catalyst. It was also shown that direction of fins must be taken into account for improving the reactivity. The influence of MP on reaction rate constant was analyzed and compared with the plate-type catalyst. Moreover, a simulation was carried out to determine the steady-state flow behavior. It was found that the streamlines went through the holes only when the holes were aligned behind the fins against the stream. This behavior corresponded with the experimental result that directions of fins are important for improving the reactivity.
