摘　　要：异丙醇-丙酮-氢气化学热泵(IAH-CHP)是一种可同时提升能量品位与实现能量存储的系统。丙酮加氢反应器是异丙醇-丙酮-氢气化学热泵系统的重要组成部分。它对异丙醇-丙酮-氢气化学热泵系统的性能具有重要的影响。本文将泡沫金属反应器用于实现丙酮加氢反应,以提升丙酮加氢的反应效率与能量利用效率。首先建立丙酮加氢泡沫金属反应器的模型,然后通过模拟计算对泡沫金属反应器与颗粒填充反应器的性能进行了研究。研究结果表明:对于丙酮加氢等慢速反应,考虑壁面传热时,泡沫金属反应器的性能优于颗粒填充反应器。主要原因为泡沫金属反应器具有好的壁面传热特性与低的压降。Isopropanol-acetone-hydrogen chemical heat pump（IAH-CHP） is a system which can simultaneously achieves the upgrade of energy level and the energy storage.Acetone hydrogenation reactor is one of the most important parts of IAH-CHP and has a decisive influence on the performance of IAH-CHP.In this work,the metal foam reactor is introduced for acetone hydrogenation to improve its reaction and energy utilization performances.A detailed reactor model of metal foam reactors is built for slow reactions using acetone hydrogenation as an example.The superiorities of metal foam reactors to particles-packed reactors are numerically studied.Good wall heat transfer characteristic and low pressure drop make metal foam reactors for acetone hydrogenation over amorphous Raney nickel catalyst superior to particles-packed reactors in performance.
