Abstract

The invention discloses a self-heating type reactor used for hydrogen production by reforming and filled with a high-temperature phase-change material. The self-heating type reactor used for hydrogen production by reforming is formed by sequentially laminating an upper cover plate provided with a methanol steam reforming reactant inlet pipe and a methanol catalytic combustion reactant inlet pipe on the upper surface, a graphite washer, an upper evaporation plate, a graphite washer, a lower evaporation plate, a graphite washer, a methanol reforming heat absorbing plate for hydrogen production filled with the high-temperature phase-change material on the lower surface, a sealing plate, a graphite washer, a methanol catalytic combustion plate filled with the high-temperature phase-change material on the lower surface, a graphite washer and a lower cover plate provided with a reformed gas outlet pipe and a combustion tail gas outlet pipe on the lower surface from top to bottom. The heat stability of a self-heating reactor is effectively improved by means of latent heat of phase change of the high-temperature phase-change material, the temperature gradient in the reactor and the temperature fluctuation of the reactor during working are reduced, catalyst activity reduction and peeling caused by overheating of the reactor are inhibited, and the heat efficiency and the methanol conversion rate of the reactor are improved.

Description

technical field [0001] The invention relates to a micro-reactor for hydrogen production by reforming alcohols, in particular to an autothermal reforming hydrogen production reactor filled with high-temperature phase change materials. [0002] technical background [0003] With the development of human society, the demand for energy is increasing day by day. The depletion of fossil fuel reserves and the continuous aggravation of environmental pollution make it urgent for human beings to find a clean and renewable energy source. [0004] Hydrogen energy has attracted widespread attention as a clean energy source. However, hydrogen has a low energy density and is difficult to store. The problem of hydrogen storage in mobile applications seriously hinders the application of proton exchange membrane fuel cells in mobile applications such as hydrogen vehicles. The on-site hydrogen reforming technology of methanol steam provides an effective solution to the hydrogen supply proble...
