Description
Technical field
The invention belongs to technical field of hydrogen preparation, relate to a kind of equipment preparing hydrogen, particularly relate to one and utilize first
Alcohol water prepares the equipment of hydrogen.
Background technology
In numerous new forms of energy, Hydrogen Energy will become the 21 century optimal energy.This is because, identical heavy in burning
In the case of coal, gasoline and the hydrogen of amount, the energy that hydrogen produces is most, and the product of its burning is water, do not have lime-ash and
Waste gas, does not pollutes the environment；And coal and oil combustion generate is carbon dioxide and sulfur dioxide, greenhouse effect can be produced respectively
And acid rain.Coal and reserves are limited, and hydrogen is mainly stored in water, and after burning, unique product is also water, can be in a steady stream
It is constantly be generated hydrogen, is finished never.
Hydrogen is a kind of colourless gas.One gram of Hydrogen Energy of burning discharges your heat of 142 kilojoules, is the 3 of gasoline caloric value
Times.The weight of hydrogen is particularly lightweight, and it is all gently more than gasoline, natural gas, kerosene, thus carries, transports conveniently, is space flight, aviation
Deng the most suitable fuel of the high-speed flight vehicles.Hydrogen can burn in oxygen, and the temperature of hydrogen flame may be up to 2500 DEG C,
Thus people commonly use hydrogen cutting or welding ferrous materials.
In the Nature, the distribution of hydrogen is the most extensive.Water is exactly big " warehouse " of hydrogen, wherein contains the hydrogen of 11%.In earth
There are about the hydrogen of 1.5%；All contain hydrogen in oil, coal, natural gas, animal and plant body etc..The main body of hydrogen is with the shape of compound water
Formula exists, and earth surface about 70% is covered by water, moisture storage capacity very greatly, accordingly, it can be said that hydrogen be " inexhaustible, use it
Inexhaustible " the energy.If can be with suitable method preparing hydrogen from water, then hydrogen also will be the comparatively inexpensive energy of a kind of price
Source.
Having many uses of hydrogen, the suitability is strong.It can not only be used as fuel, and metal hydride has chemical energy, heat energy
The function mutually changed with mechanical energy.Such as, hydrogen storage metal has inhales hydrogen heat release and the ability putting hydrogen of absorbing heat, can be by heat storage
Get up, use as heating and air-conditioning in room.
Hydrogen, as gaseous fuel, is first used on automobile.In May, 1976, the U.S. develops one and makees fuel with hydrogen
Automobile；Later, Japan also succeeded in developing a kind of automobile with liquified hydrogen as fuel；The latter stage seventies, running quickly of front Germany
Hydrogen is tested by motor corporation of speeding, and they have only used five kg of hydrogen, just make running car 110 kilometers.
With hydrogen as motor vehicle fuel, the most totally, the most easily start, and little to the corrosiveness of electromotor,
The service life of electromotor can be extended.Owing to hydrogen can uniformly mix with air, can save on general automobile used completely
Carburator, thus the structure of existing automobile can be simplified.More interestingly, as long as adding the hydrogen of 4% in the oil.With
It is as automobile engine fuel, so that it may fuel-economizing 40%, and without petrol engine being made great improvement.
Hydrogen certain pressure and at a temperature of easily become liquid, thus by it with iron flask car, on-highway tractor or wheel
Ship Transportation is the most very convenient.The hydrogen of liquid both can be used as the fuel of automobile, aircraft, it is possible to as rocket, the fuel of guided missile.The U.S. flies
Toward the Apollo Personnel investigation Program of the moon " Long March carrier rocket that number spacecraft and China launch a man-made satellite. is all to make fuel with liquified hydrogen
's.
It addition, use hydrogen hydrogen fuel cell Hydrogen Energy can also be directly translated into electric energy, the utilization making Hydrogen Energy is the most square
Just.At present, this fuel cell is used in spacecraft and submarine, and effect is pretty good.Certainly, due to cost relatively
Height, is also difficult to commonly use for the moment.
The annual production of hydrogen is about 36,000,000 tons the most in the world, is wherein mostly from oil, coal and natural gas
Producing, this must consume fossil fuel the most in short supply；The hydrogen separately having 4% is to produce by the method for electrolysis water, but
The electric energy consumed is too many, does not calculates, and therefore, people are trying to explore to study hydrogen manufacturing new method.And reform with methanol, water and make
Hydrogen can reduce the energy consumption in Chemical Manufacture and reduce cost, is expected to substitute the work of " water electrolysis hydrogen production " that be referred to as electricity-eating tiger
Skill, utilizes advanced methanol vapor to reform--pressure swing adsorption making pure hydrogen and rich in CO2Mixed gas, through entering one
The post processing of step, can obtain hydrogen and carbon dioxide gas simultaneously.
By catalyst, under the effect of catalyst, first is there is in methanol and steam under certain temperature, pressure condition
Alcohol cracking reaction and the transformationreation of carbon monoxide, generate hydrogen and carbon dioxide, and this is that component more than, the gas-solid of many reactions are urged
Change response system.Reactional equation is as follows:
CH3OH→CO+2H2 (1)
H2O+CO→CO2+H2 (2)
CH3OH+H2O→CO2+3H2 (3)
The H that reforming reaction generates2And CO2, then through palladium membrance separation by H2And CO2Separate, obtain high-purity hydrogen.Transformation is inhaled
The power consumption of attached method is high, equipment is big, and is not suitable for small-scale hydrogen and prepares.
Additionally, existing hydrogen producer is higher due to the temperature of waste gas, it usually needs arrange the discharge of waste gas output channel useless
Gas.The setting of waste gas output channel not only adds the volume of equipment, the most portable, has the risk scalding people simultaneously.
In view of this, nowadays in the urgent need to designing a kind of new hydrogen producer, in order to overcome the above-mentioned of existing hydrogen producer
Defect.
