Hydrogen production reactor for carrying out autothermal reforming hydrogen production employing car exhaust waste heat

Abstract

The invention discloses a hydrogen production reactor for carrying out autothermal reforming hydrogen production employing car exhaust waste heat. The hydrogen production reactor comprises a tail gas inlet pipe, a vaporization unit, a reaction unit, a heat exchange unit and a tail gas outlet pipe which are sequentially connected, wherein the heat exchange unit comprises an outer barrel, an inner barrel, an upper end plate and a lower end plate; the upper end plate and the lower end plate are block off two ends of the outer barrel and the inner barrel; a tail gas flow channel, a reforming gas flow channel and a liquid hydrocarbon material flow channel liquid hydrocarbon fuel flow channel are arranged inside the heat exchange unit; the vaporization unit comprises an outer barrel, and an upper end plate and a lower end plate block off two ends of the outer barrel; a liquid hydrocarbon fuel delivery pipe, a liquid hydrocarbon fuel flow channel and a tail gas flow channel are arranged inside the vaporization unit; the reaction unit comprises an outer barrel, an inner barrel, an upper end plate and a lower end plate; the upper end plate and the lower end plate are blocked at two ends of the outer barrel and the inner barrel; a reaction cavity, a liquid hydrocarbon fuel delivery pipe and a tail gas flow channel are arranged inside the reaction unit. The hydrogen production reactor has the advantage that the utilization rate of automotive fuel is improved.

Description

technical field [0001] The invention relates to a reactor for reforming hydrocarbon fuels to produce hydrogen, in particular to a hydrogen production reactor for autothermal reforming hydrogen production by utilizing waste heat of automobile tail gas. Background technique [0002] Against the backdrop of increasingly scarce energy resources and accelerated global warming, a global consensus has been reached on reducing the environmental pollution caused by automobile exhaust and reducing the excessive dependence of automobiles on oil. In response to the above problems, today's automobiles are mainly developed in two aspects. On the one hand, energy-saving and new energy vehicles are vigorously developed, mainly including hybrid vehicles, pure electric vehicles and fuel cell vehicles. On the other hand, while vigorously developing new energy vehicles, it is also equally important to continuously optimize and improve the structure and fuel economy performance of traditional in...
