Reaction heat removal/supply is a key issue in the development of intensified compact reactors for non-adiabatic catalytic processes. In this work, using the exothermal Fischer-Tropsch synthesis as a critical case, we show the possibility to boost the heat transfer performances of a packed-POCS (Periodic Open Cellular Structure) reactor by adding an outer metallic thermally connected skin to the conductive cellular internals. To this aim, the performances of a highly active Co/Pt/Al₂O₃ catalyst, packed in the form of 300 μm particles into the metallic structure 3D-printed in AlSi7Mg0.6, are assessed at industrially relevant operating conditions and compared with those of the same catalyst particles packed into the same POCS printed without the skin. Outstanding performances (CO conversion in excess of 80 %) are reached with flat axial and radial temperature profiles along the catalytic bed, in line with the excellent temperature control enabled by the conductive POCS. The presence of the skin strongly decreases the overall external temperature difference thanks to the enhanced thermal contact between the reactor wall and the ordered cellular structure, which governs the wall heat transfer. Accordingly, thanks to the presence of the skin, the temperature profile inside the reactor can be controlled much more effectively, thus enabling new operating windows that are not commonly accessible.

反应热去除/供应是开发用于非绝热催化过程的强化紧凑型反应器的关键问题。在这项工作中，使用放热费托合成作为关键案例，我们展示了通过将外部金属热连接皮肤添加到导电蜂窝结构来提高填充 POCS（周期性开放蜂窝结构）反应器的传热性能的可能性。内件。为此，高活性 Co/Pt/Al ₂ O _{3 的性能}以 300 μm 颗粒的形式填充到 AlSi7Mg0.6 中 3D 打印的金属结构中的催化剂，在工业相关的操作条件下进行评估，并与填充到相同 POCS 中且没有表皮打印的相同催化剂颗粒进行比较。沿着催化床的平坦轴向和径向温度曲线实现了出色的性能（CO 转化率超过 80%），这与导电 POCS 实现的出色温度控制相一致。由于反应器壁与控制壁传热的有序蜂窝结构之间增强的热接触，表皮的存在大大降低了整体外部温差。因此，由于表皮的存在，可以更有效地控制反应器内的温度分布，
