| 摘要:随着世界能源问题的日益加重,氢能作为一种高效清洁能源,对燃料电池的研究尤为重要。本文研究二甲醚的水蒸汽重整制氢过程,设计了一种带有隔热套、瓦片式加热通道和催化反应床的重整反应器。实验研究了反应气体温度、水蒸汽与二甲醚的摩尔比和反应器结构参数对二甲醚转化率、H2产率、反应器出口H2和C02含量的影响。建立了反应器的数学模型和功率模型,并利用COMSOL软件对其仿真。模拟结果显示了二甲醚水蒸汽重整制氢过程中的各组分质量分布、以及不同温度、不同水醚摩尔比下二甲醚转化率和制氢率情况。这些模拟结果提供了有用的数据,从而推动微型催化重整床反应器的设计和运行。 |
| Abstract:With the increasing energy problems in the world, hydrogen energy, as a kind of efficient and clean energy, is particularly important for the research of fuel cell.In this paper, the process of hydrogen production by steam reforming of dimethyl ether is studied. A reforming reactor with heat insulation jacket, tile heating channel and catalytic reaction bed is designed.The effects of temperature of reaction gas, molar ratio of water vapor to dimethyl ether and reactor structure parameters on the conversion rate of dimethyl ether, the yield of H2, and the content of H2 and C02 at the reactor outlet were studied experimentally.The mathematical model and power model of the reactor were established, and the COMSOL software was used to simulate the reactor.The simulation results show the mass distribution of each component, the conversion rate of dimethyl ether and the hydrogen productionrate under different temperature and water ether molar ratio.These simulation results provide useful data to promote the design and operation of micro catalytic reforming bed reactor. |
