摘　　要：电磁感应加热技术作为一种通过吸收电磁能直接转换为热能的非直接接触式加热技术,热量直接在磁性材料上迅速感应产生,无需加热整个反应器,改善了能量传递效率和高散热现象。因此,电磁感应加热为高温化学过程供了独特的解决方案,以克服使用传统加热方法时带来的加热/冷却速率缓慢、加热不均匀、低能效等问题。本文首先简述了电磁感应加热技术的加热机制以及相关的测量方法,重点介绍了电磁感应加热过程中能量效率的评估,进而总结了采用电磁感应加热技术用于高温催化反应的研究进展。最后,提出了对未来电磁感应加热技术应用于工业化过程的展望。Electromagnetic induction heating(EIH)is a non-contacting heating technology that directly absorbs and converts electromagnetic energy into heat.Heat is rapidly induced on magnetic materials without the need to heat the whole reactor,which improves energy transfer efficiency and reduces heat dissipation.Therefore,EIH provides a unique solution for high-temperature chemical processes of slow heating/cooling rate,uneven heating and low energy efficiency.This article briefly described the heating mechanism and related measurement methods of EIH,focusing on the energy efficiency evaluation.Then we summarized the research advances of EIH for high-temperature catalytic reactions.Finally,the prospect of the industrialization of EIH in the future was put forward.
