反应精馏是一种将化学反应和精馏过程集成在一台设备中的高效过程强化技术。当使用固体催化剂时，该过程也称为催化蒸馏。RD技术具有许多关键优势，例如减少资本投资和显著节能，因为它可以超越平衡限制，简化复杂过程，提高产品选择性，并提高分离效率。然而，RD还受到热力学要求（与挥发性差异和反应热有关）、调整反应和蒸馏操作条件的需要以及活性、选择性和足够寿命的催化剂的可用性的限制。本文首次对新型集成反应蒸馏技术进行了概述和深入了解，这些技术将联合收割机研发原理与其他强化蒸馏技术相结合，分隔壁塔（DWC）、循环蒸馏、HiGee蒸馏、热集成蒸馏塔（HIDiC）以及膜、微波或超声辅助蒸馏--这些技术可能导致新工艺和应用的开发。
Reactive distillation (RD) is an efficient process intensification technique that integrates chemical reaction and distillation in a single apparatus. The process is also known as catalytic distillation when a solid catalyst is used. RD technology has many key advantages such as reduced capital investment and significant energy savings, as it can surpass equilibrium limitations, simplify complex processes, increase product selectivity, and improve separation efficiency. However, RD is also constrained by thermodynamic requirements (related to volatility differences and heat of reaction), the need to align the reaction and distillation operating conditions, and the availability of catalysts that are active, selective, and with sufficient longevity. This paper is the first to provide an overview and insights into novel integrated reactive distillation technologies that combine RD principles with other intensified distillation technologies-e.g., dividing-wall column (DWC), cyclic distillation, HiGee distillation, heat-integrated distillation column (HIDiC), and membrane-, microwave-, or ultrasound-assisted distillation-potentially leading to the development of new processes and applications.
