在传统反应器中进行的具有快速本征动力学的放热反应通常受到传热的限制。这会导致热点的形成，影响复杂反应的产物分布，并可能导致反应器失控。微结构反应器（MSR）已成功用于此类反应，提高了温度控制和安全性。尽管不同的 MSR 概念已应用于各种工艺，但文献中对一般设计标准的讨论仍然很少。在这篇综述中，描述了传统单注射 MSR 中的温度管理。详细讨论了反应器安全性和稳定性以及混合的作用等重要问题。随后，介绍了多次注射反应器的概念，并提出了一个用于研究温度分布的简化模型。最后，强调了多次注射 MSR 设计中的优点和关键问题。
The exothermic reactions with fast intrinsic kinetics when carried out in conventional reactors are often limited by heat transfer. This results in the formation of hot spots, which affects product distribution of complex reactions and may lead to reactor runaway. Microstructured reactors (MSR) have been successfully used for this type of reaction, gaining increased temperature control and enhanced safety. Although different MSR concepts have been applied to various processes, the general design criteria are still poorly discussed in the literature. In this review, temperature management in conventional single injection MSR is described. The important issues, such as reactor safety and stability, along with the role of mixing, are discussed in detail. Subsequently, the multi-injection reactor concept is introduced and a simplified model developed to investigate the temperature profile is presented. Finally, the benefits and critical issues in the design of multi-injection MSR are highlighted.
