Technical field
The utility model belongs to technical field of hydrogen preparation, relates to a kind of hydrogen producer, relates in particular to a kind of hydrogen producer that needs low-power machine; Simultaneously, the utility model also relates to the hydrogen production process of above-mentioned hydrogen producer.
Background technology
In numerous new forms of energy, Hydrogen Energy will become the optimal energy of 21 century.This be because, under the situation of coal, gasoline and hydrogen of burning identical weight, the most energy that hydrogen produces, and its incendiary product is water, do not have lime-ash and waste gas, do not pollute the environment; And coal and oil combustion generate is carbonic acid gas and sulfurous gas, can produce Greenhouse effect and acid rain respectively.Coal and reserves are limited, and hydrogen mainly is stored in the water, and the unique product in burning back also is a water, can produce hydrogen continuously, uses up never.
Hydrogen is a kind of colourless gas.Burning one gram Hydrogen Energy discharges your heat of 142 kilojoules, is 3 times of gasoline thermal value.The weight of hydrogen is light especially, and it has all gently been howed than gasoline, Sweet natural gas, kerosene, thereby carries, transports conveniently, is the only fuel of the high-speed flight vehicles such as space flight, aviation.Hydrogen can burn in oxygen, and the temperature of hydrogen flame can be up to 2500 ℃, thereby people's hydrogen cutting commonly used or weldsteel iron material.
In the Nature, the distribution of hydrogen is very extensive.Water is exactly big " warehouse " of hydrogen, wherein contains 11% hydrogen.There is 1.5% hydrogen the earth Rio; All contain hydrogen in the oil, coal, Sweet natural gas, animal and plant body etc.The main body of hydrogen is that the form with compound water exists, and earth surface about 70% is covered by water, and moisture storage capacity is very big, therefore we can say that hydrogen is the energy of " inexhaustible, nexhaustible ".If can from water, produce hydrogen with suitable method, hydrogen also will be the quite cheap energy of a kind of price so.
Having many uses of hydrogen, suitability is strong.It can not only be used as fuel, and metal hydride has the function that chemical energy, heat energy and mechanical energy are changed each other.For example, hydrogen storage metal has inhales hydrogen heat release and the ability of absorbing heat and putting hydrogen, can heat be stored, and uses as heating and air-conditioning in the room.
Hydrogen at first is used on the automobile as geseous fuel.In May, 1976, the U.S. develops a kind of automobile of making fuel with hydrogen; Afterwards, Japan also to succeed in developing a kind of be the automobile of fuel with the liquid hydrogen; In the latter stage seventies, the Mercedes of preceding Germany tests hydrogen, and they have only used five kg of hydrogen, has just made running car 110 kilometers.
, not only clean with hydrogen as automobile fuel, start easily at low temperatures, and little the corrosive nature of mover, can prolong the work-ing life of mover.Because hydrogen and air can uniform mixing, can save vaporizer used on the general automobile fully, thereby can simplify the structure that has automobile now.More interesting is to need only the hydrogen of adding 4% in gasoline.Use it as motor car engine fuel, but just fuel-economizing 40%, and need not petrol engine is done great improvement.
Hydrogen is easy to become liquid under certain pressure and temperature, thereby it is all very convenient with 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 fly to Apollo Personnel investigation Program of the moon of the U.S. " Long March launch vehicle that number spaceship and China launch a man-made satellite., all make fuel with liquid hydrogen.
In addition, use hydrogen-hydrogen fuel cell directly to change into electric energy to Hydrogen Energy, make utilizing of Hydrogen Energy more convenient.At present, this fuel cell has obtained using on spaceship and undersea boat, and effect is pretty good.Certainly, because cost is higher, also be difficult to generally use for the moment.
The YO of hydrogen is about 3,600 ten thousand tons in the world now, and wherein the overwhelming majority is produced from oil, coal and Sweet natural gas, and this must consume original just mineral fuel very in short supply; The hydrogen that other has 4% is to produce with the method for brine electrolysis, but the electric energy that consumes is too many, does not calculate very much, and therefore, people are trying to explore to study the hydrogen manufacturing novel method.And can reduce the energy consumption in the Chemical Manufacture and reduce cost with methyl alcohol, water reformation hydrogen production, be expected to substitute the technology of " water electrolysis hydrogen production " that be called as electricity-eating tiger, utilize advanced methanol vapor to reform---pressure swing adsorption is produced pure hydrogen and is rich in CO
2Mixed gas, through further aftertreatment, can obtain hydrogen and carbon dioxide gas simultaneously.
Methyl alcohol and water vapour pass through catalyzer under certain temperature, pressure condition; Under the effect of catalyzer; The transformationreation of methanol decomposition reaction and carbon monoxide takes place, generate hydrogen and carbonic acid gas, this is the gas solid catalytic reaction system of component more than, many reactions.Reactional equation is following:
CH
3OH→CO+2H

H
2O+CO→CO
2+H
2 (2)
CH
3OH+H
2O→CO

2 (3)
The H that reforming reaction generates
2And CO
2, pass through pressure swing adsorption process (PSA) or palladium membrane sepn again with H
2And CO
2Separate, obtain high-purity hydrogen.The power consumption of pressure swing adsorption process is high, equipment is big, and is not suitable for small-scale Preparation of Hydrogen.
In addition, existing hydrogen producing apparatus needs powerful motor in order to let device start, and more than 3000KW (as shown in Figure 1) usually, only motor just need take a large amount of spaces, and the equipment that makes can't miniaturized, and movability is also very poor.
