摘要

甲醇蒸汽重整制氢在移动氢能源供应和分布式发电领域具有广阔的应用潜力。采用电磁感应加热技术能使反应器实现快速热响应。与外部加热或内部电加热相比可大大缩短启动时间，有望提升甲醇蒸汽重整制氢反应器的效率和性能。建立了电磁感应加热甲醇蒸汽重整制氢反应器的二维轴对称模型，并探究了感应线圈结构参数、激励条件和反应物入口条件变化对反应器出口温度和制氢性能的影响。结果表明，通过调节线圈激励电流和激励频率可实现对反应器的快速加热。线圈匝数越多、间距越小且线圈距离反应器越近，则磁场强度越强，反应器出口温度越高。减小反应物入口流速、提高进口温度和水蒸气与甲醇物质的量之比都有利于甲醇转化率的提高。在水蒸气与甲醇物质的量之比为1.1、进口温度为420 K、入口流速为0.05 m/s，线圈匝数为7匝、线圈间距为4.0 mm、激励频率为25 kHz和激励电流为120 A条件下，反应器出口温度能迅速达到572 K，甲醇转化率达到99.6%。

Abstract

Hydrogen production by methanol steam reforming has broad application potential in the field of mobile hydrogen energy supply and distributed power generation. Electromagnetic induction heating technology can make the reactor achieve fast thermal response. Compared with external heating or internal electric heating

the start-up time is greatly reduced

which is expected to improve the efficiency and performance of the methanol steam reforming hydrogen production reactor. A two-dimensional axisymmetric model of methanol steam reforming hydrogen production reactor with electromagnetic induction heating was established

and the effects of induction coil structure parameters

excitation conditions and reactant inlet conditions on the reactor outlet temperature and hydrogen production performance were investigated. The results show that the reactor can be heated up quickly by adjusting the coil excitation current and excitation frequency. The more numbers of coil turns

the smaller the pitch and the closer the width of the coil from the wall

the stronger the magnetic field intensity and the higher the reactor outlet temperature. Reducing the inlet flow rate of reactant

increasing the inlet temperature of reactant and the steam-to-methanol ratio are all beneficial to methanol conversion. Under the conditions of the molar ratio of water vapor to methanol of 1.1

the inlet temperature of 420 K

the inlet flow velocity of 0.05 m/s

the coil turn number of 7

the coil distance of 4.0 mm

with the excitation frequency of 25 kHz and the excitation current of 120 A

the reactor outlet temperature can rapidly reach 572 K

and the methanol conversion rate achieves 99.6%.
