In numerous new forms of energy, Hydrogen Energy will become the 21 century optimal energy.This is because when burning the coal of identical weight, gasoline and hydrogen, the energy that hydrogen produces is maximum, and the product of its burning is water, does not have lime-ash and waste gas, does not pollute the environment; And coal and oil combustion generate is carbon dioxide and sulfur dioxide, greenhouse effects and acid rain can be produced respectively.Coal and reserves are limited, and hydrogen is mainly stored in water, and after burning, unique product is also water, can produce hydrogen continuously, be finished never.
Hydrogen is a kind of colourless gas.One gram of Hydrogen Energy of burning discharges your heat of 142 kilojoules, is 3 times of gasoline caloric value.The weight of hydrogen is light especially, and it is all lighter than gasoline, natural gas, kerosene many, and thus carrying, transport conveniently, is the most suitable fuel of the high-speed flight such as space flight, the aviation vehicles.Hydrogen can burn in oxygen, and the temperature of hydrogen flame can up to 2500 DEG C, and thus people commonly use hydrogen cutting or weldable steel iron material.
In the Nature, the distribution of hydrogen is very extensive.Water is exactly large " warehouse " of hydrogen, wherein contains the hydrogen of 11%.There is the hydrogen of 1.5% earth Rio; All contain hydrogen in oil, coal, natural gas, animal and plant body etc.The main body of hydrogen exists with the form of compound water, and earth surface about 70% is covered for water, and very greatly, therefore can say, hydrogen is the energy of " inexhaustible, nexhaustible " to moisture storage capacity.If can with suitable method preparing hydrogen from water, so hydrogen also will be the energy that a kind of price is quite cheap.
Having many uses of hydrogen, applicability is strong.It can not only be used as fuel, and metal hydride has the function that chemical energy, heat energy and mechanical energy change mutually.Such as, hydrogen storage metal has to inhale hydrogen heat release and absorb heat puts the ability of hydrogen, heat storage can be got up, use as heating in room and air-conditioning.
Hydrogen, as gaseous fuel, is first used on automobile.In May, 1976, the U.S. develops a kind of automobile making fuel with hydrogen; Afterwards, Japan also succeeded in developing a kind of take liquified hydrogen as the automobile of fuel; In the latter stage seventies, the Mercedes of front Germany tests hydrogen, and they have only used five kg of hydrogen, just makes running car 110 kilometers.
With hydrogen as motor vehicle fuel, not only totally, easily start at low temperatures, and little to the corrosiveness of engine, the service life of engine can be extended.Because hydrogen and air can Homogeneous phase mixing, vaporizer used on general automobile can be saved completely, thus the structure of existing automobile can be simplified.More interestingly, if add in the oil 4% hydrogen.Use it as automobile engine fuel, just can fuel-economizing 40%, and without the need to doing great improvement to petrol engine.
Hydrogen is easy to become liquid under certain pressure and temperature, thus that it is all very convenient by iron flask car, on-highway tractor or ship transportation.Liquid hydrogen both can be used as the fuel of automobile, aircraft, also can be used as the fuel of rocket, guided missile.The U.S. is flown to the Apollo Personnel investigation Program of the moon " Long March carrier rocket that number spaceship and China launch a man-made satellite., all make fuel with liquified hydrogen.
In addition, use hydrogen-hydrogen fuel cell Hydrogen Energy directly can also be changed into electric energy, make utilizing of Hydrogen Energy more convenient.At present, this fuel cell is used on spaceship and submarine, and effect is pretty good.Certainly, because cost is higher, be also difficult to generally use for the moment.
The annual production of hydrogen is about 3,600 ten thousand tons in the world now, and wherein the overwhelming majority is produced from oil, coal and natural gas, and this must consume fossil fuel natively very in short supply; Separately have the hydrogen of 4% to be produce by the method for brine electrolysis, but the electric energy consumed is too many, does not calculate very much, therefore, people are trying to explore research hydrogen manufacturing new method.And the energy consumption in Chemical Manufacture can be reduced with methyl alcohol, water reformation hydrogen production and reduce costs, be expected to substitute and be called as the technique of " water electrolysis hydrogen production " of electricity-eating tiger, utilize advanced methanol vapor to reform--pressure swing adsorption making pure hydrogen and be rich in CO
2mist, through further post processing, hydrogen and carbon dioxide gas can be obtained simultaneously.
Methyl alcohol and steam pass through catalyst under certain temperature, pressure condition, under the effect of catalyst, the transformationreation of methanol decomposition reaction and carbon monoxide occurs, generates hydrogen and carbon dioxide, this is the gas solid catalytic reaction system of component more than, many reactions.Reactional equation is as follows:
CH
3OH→CO+2H
2(1)
H
2O+CO→CO
2+H
2(2)

The H that reforming reaction generates
2and CO

2be separated, obtain high-purity hydrogen.The power consumption of pressure swing adsorption method is high, equipment large, and is not suitable for the preparation of small-scale hydrogen.
Beneficial effect of the present invention is: the rich hydrogen oven that the present invention proposes, and can reduce the pollution because barbecue produces, be convenient to again roast out of doors.The hydrogen producer volume of hydrogen manufacturing oven of the present invention is little, and be easy to carry, hydrogen conversion is high, safety and environmental protection.
In addition, the rich hydrogen oven of the present invention without the need to the step of purifying hydrogen of hydrogen, after reformation hydrogen production, directly by hydrogen for oven, preparation efficiency is higher, and conversion ratio is also effectively promoted, and improves the effective rate of utilization to resource simultaneously.
