Description
Technical field
It is technical in preparing hydrogen by reforming methanol that the present invention relates to a kind of preparation methods of igniter catalyst and igniter catalyst
Using in particular to a kind of igniter catalyst and its preparation method and application of hydrogen quick catalysis igniting.
Background technique
Currently, there are many fuel gas sparking mode in industrial application, aerospace applications and life production application,
It is mostly based on the mode of electric ignition (electrically heated rod or electricity sparking) formula or precious metal catalyst igniting.Electric sparking mode technology maturation,
And reliability is higher, but needs to configure electric energy of the corresponding power supply for starting ignition, service life and number are limited.Noble metal
Catalytic ignition mode initially starts from platinum filament, and development later is platinum powder, and development was noble metal composite later, and noble metal is adhered to
On catalyst carrier (such as aluminium oxide, silica etc.), used as igniter catalyst.The mode of electric ignition has electrically heated rod
(heater igniter) and electricity sparking (spark igniter) two ways；In addition, an if maintenance flare (pilot
Flame), without electricity sparking.Certainly maintaining flare, igniting still needs electric ignition for the first time.
Under normal circumstances, hydrogen and oxygen react required temperature at 500 DEG C or more, and hydrogen molecule is due in height at this time
The intermolecular probability for occurring freely to collide is increased under the conditions of temperature, shows higher-energy state, so as to which oxygen occurs with oxygen
Change reaction.But in the presence of a catalyst, the activation energy of hydrogen oxygen composite reaction reduces, so that hydrogen molecule is in lower energy
Also recombination reaction can occur with oxygen under state.When i.e. hydrogen is by adsorption of metal ions, hydrogen atom is activated, and is adsorbed on gold
Hydrogen atom or hydrogen ion on category ion further react with oxygen under the conditions of relatively mild.Based on principles above, urge
Change igniting to be widely used.
Usual carried noble metal igniter catalyst technology of preparing uses infusion process, coating process and chemical deposition, colloid
The technologies such as method, however the technologies such as chemical deposition, colloid method preparation process is complicated, is not easy to mass production, is relatively suitable for real
Room is tested, coating process is suitable for doing film class, and infusion process is suitable for various situations, and by a relatively simple, is suitable for batch production.
The invention patent based on the above reasons and the optimization of our company's independent research preparing hydrogen by reforming methanol technology, devises one
Kind is using the method for simply preparing igniter catalyst.This method is prepared for a kind of efficient hydrogen by allotment bullion content
Igniter catalyst, and it is technical that the catalyst is used for preparing hydrogen by reforming methanol.

Afterwards, it is placed in insulating box, insulating box initial temperature is set as 80-150 DEG C, dries 1-2 hour, then set calorstat temperature to
It 250-350 DEG C, is cooled to room temperature after activating 3-5 hour to get required Hydrogen Ignition catalyst is arrived.
Preferably, the drying and roasting activation cooling of the step (6) is to be put into Intermediate Catalyst in air dry oven first
At 80-150 DEG C, dry 1-2 hour, then 250-350 DEG C is set by calorstat temperature, it is cooled to after activating 3-5 hour
Room temperature to get arrive required Hydrogen Ignition catalyst.
Preferably, by the coating number of regulating step (5) make noble metal content be 0.1wt%-0.5wt% or
0.5wt%-1wt%.
Preferably, the noble metal in the step (1) is platinum or palladium.
Another aspect of the present invention, the catalyst include active component, combustion adjuvant, dispersing agent and carrier；The activity

Metaplasia produces preparation；And igniter catalyst igniting is lasted a long time compared with electric ignition, for active component noble metal itself, is urged
Agent is placed on above combustion furnace, is only done igniting and is used；Burning after igniting carries out below catalyst, catalyst own temperature
500 DEG C are not exceeded, no life span；Drying can quickly slough Intermediate Catalyst surface free water at 80-150 DEG C, intermediate
Catalytic inner moisture is also migrated from inner aperture to macropore, is finally migrated to surface, is sloughed, while internal active component also can
With water translocation to Intermediate Catalyst surface.The reason of roasting at 250-350 DEG C, selecting this temperature section is: 1) roasting removes
H2O.Al2O3Volatilizable component NH in middle combination water and ammonium salt3；2) roasting can be such that active component has at this temperature
Stable catalytic activity simultaneously maintains certain crystal particle size；If 3) maturing temperature is excessively high, active group distribution may result in
Raw sintering phenomenon causes catalyst inactivation or catalytic performance to decline.The selection reason of calcining time is following two points: 1) roasting
Time is short: water and volatilizable component NH are combined in catalyst3Remove insufficient, active component is unstable, and catalyst performance is unstable
It is fixed；2) appropriate calcining time to combine water and volatilizable component NH in catalyst3Sufficiently, catalyst activity component reaches for removal
Stable state, catalyst performance stabilised.
