Description
Technical field:
The present invention relates to Technology for Production Hydrogen from Methanol fields, are especially a kind of small-sized automatically controlled double heat source alcohols hydrogen production from catalytic pyrolysis
Application method on device and its liquid fuel within automobile.
Background technique:
Hydrogen is current most light molecule, it exists in a manner of compound in nature.It can be discharged when hydrogen is with oxygen chemical combination
Big energy out.Hydrogen is easy to uniformly mix with air, and inflammability limit is 4.1~75%, and maximum flame propagation velocity is
291cm/s, maximum flame propagation velocity are 7.72 times of gasoline.Use hydrogen and gasoline, diesel oil, natural gas mixed, meeting band
Carry out the improvement that economy, dynamic property and engine distribute performance, the burning velocity of reason hydrogen is fast, and crude fuel mixes certain proportion
Hydrogen after, the rapid combustion period of fuel can be greatly shortened, increase efficiency of combustion.After hydrogen is added especially in diesel engine, by
Very wide (4.1~75%) in the inflammability limit of hydrogen, internal cylinder temperature once reaches its ignition temperature, hydrogen just ignition.
Since the flame propagation velocity of hydrogen is more faster than diesel oil, one combust of diesel oil is pushed, improves cylinder endogenous fire flame propagation velocity,
Fuel faster burns, and shortens diesel engine rapid combustion period.In this period, due to increased flame speeds, the fuel of consumption is also than original
It is next more, decline the combustion mixture concentration of ormal combustion period, reduce the quantity of diesel oil under anoxia condition, reduce gas oil pyrolysis, produces
The factor of raw free carbon.Ormal combustion period shortens, and destroys the condition of soot (PM2.5) formation, can significantly reduce diesel oil hair
The particulate emission of motivation.Suitable incorporation hydrogen, the characteristic that diesel engine can be kept original may also reach up no particulate matter
Discharge.Currently, the hydrogen production process majority of the prior art uses alcohols cracking hydrogen production method, such as methanol or ethyl alcohol, they be carbon,
The compound of hydrogen, oxygen can resolve into hydrogen (H in the case where heating, decompression, catalysis2) and carbon monoxide (CO).
The Authorization Notice No. that the applicant has applied is that the patent of invention of CN1111647C discloses a kind of reduction diesel oil hair
The method and its smoke purification equipment of motivation soot are mainly characterized by the confession using Vehicular exhaust and low-voltage electric heating
Heat makes alcohols catalytic pyrolysis obtain hydrogen (H2) and carbon monoxide (CO), so as to economy, diesel oil is easily greatly lowered
Engine soot generation reaches low-carbon cigarette, or even without soot emissions, and reduces NO simultaneouslyxDischarge.
However pass through constantly practice for many years, it has been found that there are two defects for the smoke purification equipment: 1, entering alcohol
The contact area of the catalyst in motor exhaust and reaction chamber in class cracking reaction room is fewer, i.e. the heat-absorbent surface of catalyst
Product is smaller, to reduce the utilization rate of engine tail gas heat quantity；2, the methanol for carrying out catalytic pyrolysis is needed in original device is
Work by methanol pump in methanol tank from being quantitatively pumped into methanol decomposition reaction chamber, since quantity of methyl alcohol is not to supply as needed
Give, therefore the ability of catalyst is not fully utilized, can not preferably guard catalyst, eventually lead to shortening catalyst
Service life.
At the same time, it has been found that original reduce engine soot generation method there is also following two defects: 1, it is known that
Combustion position of the engine in starting heating, idle running is very poor, and discharge amount is big, and original method only passes through a pressure balance
Tank and a solenoid valve are by the hydrogen of former smoke purification equipment and carbon monoxide exhaust outlet and motor intake manifold manifold entrance
Place's connection, the volume very little of pressure balancing tank only serve the effect that pressure is balanced when air inlet, do not store hydrogen substantially, therefore should
Method is unable to improve combustion position of the engine in starting heating, idle running；2, original method by hydrogen and carbon monoxide only
It is introduced at motor intake manifold manifold entrance, therefore enters the hydrogen and an oxygen at each cylinder inlet manifold inlet valve of engine
Changing carbon sendout, there are biggish differences.
