The energy transition requires an extensive employment of gas-solid catalytic chemical reactors to support the long-term energy storage. Many renewable resources are decentralised, so that the feedstock for the energy conversion facilities is limited. New reactor technologies will be needed to ensure the efficient conversion of renewable resources in smaller scale than the state-of-the-art processes. Process intensification is a key in this direction, fulfilling the desired conversion efficiency, miniaturization of the process units and integration with the existent facilities. This paper analyses the key aspects of process intensification to be considered and implemented in the development of chemical reactors for the energy transition. The intensification strategies should follow three main directions: miniaturization of the process units, enhanced process efficiency and high reactor flexibility. An effective tackling of these directions is challenging for the standard packed-bed reaction technology, but many alternative and promising options are available. An efficient utilization of reaction engineering principles in the design of the new processes can successfully open the way to the optimal equipment selection for each specific application. Hence, a rationally based, but creative selection of the available technologies will be an essential step in the successful implementation of chemical technology in the energy transition.

能源转型需要广泛使用气固催化化学反应器来支持长期储能。许多可再生资源是分散的，因此能源转换设施的原料是有限的。将需要新的反应堆技术来确保可再生资源的有效转化，其规模小于最先进的工艺。工艺强化是这个方向的关键，实现所需的转换效率、工艺单元的小型化以及与现有设施的集成。本文分析了在开发用于能源转型的化学反应器中要考虑和实施的过程强化的关键方面。集约化战略应遵循三个主要方向：工艺单元的小型化，提高工艺效率和高反应器灵活性。对于标准填充床反应技术而言，有效解决这些方向具有挑战性，但有许多替代和有希望的选择可用。在新工艺设计中有效利用反应工程原理可以成功地为每个特定应用的最佳设备选择开辟道路。因此，对可用技术进行合理但创造性的选择将是在能源转型中成功实施化学技术的重要步骤。在新工艺设计中有效利用反应工程原理可以成功地为每个特定应用的最佳设备选择开辟道路。因此，对可用技术进行合理但创造性的选择将是在能源转型中成功实施化学技术的重要步骤。在新工艺设计中有效利用反应工程原理可以成功地为每个特定应用的最佳设备选择开辟道路。因此，对可用技术进行合理但创造性的选择将是在能源转型中成功实施化学技术的重要步骤。
