Embodiment 1

[0061] Target 2.2 L / min Hydrogen

[0062] Catalytic steam reactor temperature 360°C

[0063] Water / Methanol Molecular Number Ratio 1.8

[0064] 73%H 2 , 25% CO 2 , 0.9% CO

[0065] Estimated Processed Concentration Data

[0066] H 2 >99%, CO 2 <90ppm, CO<14ppm

Embodiment 2

[0068] Target 5.0 L / min Hydrogen

[0069] Catalytic steam reactor temperature 440°C

[0070] Water / Methanol Molecular Number Ratio 1.78

[0071] 74%H 2 , 24% CO 2 , 0.8% CO

[0072] Estimated processed concentration data

[0073] h 2 >99%, CO 2 <50ppm, CO<10ppm

[0074] The concentration of pure hydrogen can be separated from 76% to 99.999995%.

[0075] The hydrogen fuel supply system for internal combustion engines of the present invention can be used directly on existing internal combustion engines because it can quickly separate hydrogen from the mixed gas of methanol and water vapor, using gasoline cylinders as methanol storage tanks. After combining other units, it can directly supply the fuel required by the internal combustion engine, which can avoid the inconvenience and danger of installing a hydrogen storage tank for the traditional internal combustion engine that uses hydrogen, and improve the efficiency of the internal combustion engine.

Abstract

This invention is a hydrogen supply system for internal-combustion engine, especially a quick hydrogen generation for the fuel to an internal-combustion engine and as a subsidiary fuel to gasoline to improve the environmental protection ability to present internal-combustion engine. The system comprises vapor generator, a methanol injector, a spark heater, a catalytic reactor, a hydrogen separation unit, a heat management unit, a three-step controller, a CO oxidation unit and battery set. Inject a mix of vapor and methanol into the spark heater then go through the catalytic reactor to generate hydrogen. By this method, hydrogen could be obtained quickly without additional hydrogen storage tanks.

Description

technical field [0001] The present invention relates to a hydrogen fuel supply system for internal combustion engines, in particular to a hydrogen separation system that separates hydrogen from methanol and supplies it to various power engines as an energy source, so that it can be used as an auxiliary fuel for gasoline and provided for existing internal combustion engines to improve environmental protection effect. Background technique [0002] At present, with the development of science and technology and the extensive use of resources, air pollution has become a thorny problem that people have to face and improve, and related products for the purpose of environmental protection are also coming out one after another. Among the products that cause environmental pollution is the exhaust gas emitted by automobiles. Although some people have invented electricity and solar energy one after another in order to replace gasoline, they have not been popularized due to immature rese...
