Isopropanol - Acetone - Hydrogen Chemical heat pump (IAH-CHP) is a system that enhances both energy grade and energy storage. The acetone hydrogenation reactor is an important part of the isopropanol-acetone-hydrogen chemical heat pump system. It has a significant impact on the performance of the isopropanol-acetone-hydrogen chemical heat pump system. In this paper, the foam metal reactor for the acetone hydrogenation reaction to enhance the reaction of acetone hydrogenation efficiency and energy efficiency. First, a model of acetone hydrogenated foam metal reactor was established, and then the performance of foam metal reactor and particle filled reactor was studied by simulation. The results show that for slow reaction such as acetone hydrogenation, the performance of the foam metal reactor is better than that of the particle-filled reactor in consideration of the wall heat transfer. The main reason is the foam metal reactor has good wall heat transfer characteristics and low pressure drop.
