Description
Technical field
A kind of methanation reaction device is the utility model is related to, particularly a kind of rotation material filling type methanation reaction device
Methanator.
Background technology
Due to the energy general layout that China is " rich coal, oil-poor, few gas ", in order to meet the growing consumption of domestic natural gas
Demand, in addition to inlet natural gas, also to strengthen conversion of the natural gas from other resources, wherein from carbonaceous material（Such as coal, biology
Matter and coke etc.）It is a main gas source to be gasificated into synthesis gas and natural gas is made through methanation reaction again, secondly also
There is the auxiliary product of coke --- coke-stove gas is also an important channel for producing natural gas.With CO, CO2And H2Deng for mainly
Other sources of the gas such as synthesis gas, coke-stove gas, methanol purge gas and blast furnace gas of composition（Hereinafter referred to as unstripped gas herein）Original
Material gas produces the process of natural gas, must all pass through methanation reaction.
Methanation reaction is the strong exothermal reaction of volume-diminished, and the adiabatic temperature rise of every 1% CO conversions is about 72 in gas
DEG C, every 1% CO2The adiabatic temperature rise of conversion is about 60 DEG C, therefore need to remove heat caused by methanation reaction in time, is otherwise flown
Temperature will cause catalyst storehouse to inactivate and damage equipment, or even the normal production of the influence that causes the accident, and therefore, control the reaction of methanation

It carries out isolation insulation, causes equipment heavier, and the high-temperature water vapor generated in addition by methanation reaction has to refractory material
Corrosion function, periodic maintenance and replacing to refractory material are wasted time and energy.Methanation isotherm formula fixed bed is typically at about 450 DEG C
Use, though being not required to carry out isolation insulation using refractory material, catalyst storehouse loadings are few, and device structure is complicated, manufacturing cost
Height, and the later stage be not easy repair and maintenance.In addition, methanation fixed bed reactors are because of the easy skewness of gas, local methanation reaction
Acutely, local temperature runaway can cause catalyst storehouse to inactivate and damage equipment, therefore fixed bed reactors amplification is difficult, it is difficult to be applicable
The large-scale methanation reaction for producing Natural Gas Projects.
