Self-heating type reactor used for hydrogen production by reforming and filled with high-temperature phase-change material

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.
