Description
Technical field
Present invention relates particularly to a kind of ethylene glycol hydrogenation reactor.
Background technology
It is an important channel prepared by ethylene glycol that oxalic acid, which is hydrogenated to ethylene glycol, in the process of ethylene glycol hydrogenation reaction
In, coking phenomenon can be produced, caused coking material can be attached to the surface of catalyst, cause the failure of catalyst, coking material meeting
Catalyst is mutually bonded together, a tabular block is formed, hinders the smooth diffusion of unstripped gas, influences the reaction effect of unstripped gas
Rate.With increasing for coking material, more catalyst lose activity, the reaction efficiency continuous decrease of unstripped gas, when unstripped gas
When will to a certain extent under reaction efficiency, it is necessary to more catalyst changeout, to ensure the operational efficiency of equipment.
Coking phenomenon in hydrogenation process has become a key factor for restricting hydrogenation reaction efficiency, in order to subtract
Catalyst is changed to the sheet of rule by few catalyst failure phenomenon caused by coking, people by strip, and by catalyst
Shrinkage factor be changed to 3% or so by 20% or so, change the shape and shrinkage factor of catalyst, to reduce coking phenomenon have it is certain
Effect, but the generation of coking phenomenon can not be hindered, coking phenomenon there is no effective solution method at present.
When the coking phenomenon in reactor reaches a timing, it is necessary to whole replacings are carried out to the catalyst in reactor,
The replacing of catalyst not only needs to consume substantial amounts of manpower, and because the operating space in reactor is limited, changes urge every time
Agent is required to longer time, in addition, every time with catalyst changeout when, can all lose a certain amount of catalyst.Catalyst is more
Change and loss that catalyst change is can all affect to the service efficiency and product cost of reactor.
Therefore in the case where coking phenomenon can not be fully solved, how to improve the replacing efficiency of catalyst and reduce replacing
When catalyst loss turn into one problem of industry.
The content of the invention
For improve catalyst replacing efficiency, and on this basis reduce catalyst change when consumption, the application propose
A kind of reactor, the reactor are provided with radial direction frame component in dismountable, make due to Causes of Coking and during more catalyst changeout,
Without being changed to whole catalyst, only the catalyst for being formed in part with coking material is changed, reduced therefrom

In the present invention, a synthesis gas air inlet tube assembly is specially provided with to substitute current radial air inlet pipe, and this sets
A cocatalyst chamber for being used for loading catalyst is put, when the present invention works, in the cocatalyst chamber and major catalyst
Catalyst is filled with chamber, the unstripped gas entered from synthesis gas inlet tube is reacted in cocatalyst chamber first, then
Carried out in major catalyst chamber is entered, during the course of the reaction, coking phenomenon is only occurred in cocatalyst chamber and will slowly urged
Pore plugging between agent, coking is existing to be not present in major catalyst chamber., will after reactor runs to setting time
Synthesis gas air inlet tube assembly is taken out by synthesis gas inlet tube, and the catalyst in cocatalyst chamber is changed, then will be complete
Synthesis gas air inlet tube assembly into catalyst change is installed in shell by synthesis gas inlet tube, continues to produce.Using
After the present invention, the reason for coking phenomenon is only occurred in cocatalyst chamber be probably due to：When unstripped gas is having just enter into auxiliary catalysis
When in agent chamber, because the concentration of reactant in unstripped gas is higher, the motive force of reaction is larger, is drastically released in course of reaction a large amount of
Heat, this make it that the reaction temperature in cocatalyst chamber is too high, and analysis carbon coking phenomenon occurs in organic moiety in part material,
After unstripped gas is entered in major catalyst chamber, unstripped gas is rapidly diffused into whole major catalyst chamber, makes the concentration of reactant
Rapid to reduce, reaction temperature is returned in normal range (NR), analysis carbon coking phenomenon no longer occurs.Coking phenomenon in cocatalyst chamber
After reaching to a certain degree, you can to the catalyst change in cocatalyst chamber in synthesis gas air inlet tube assembly, at this moment due to sponsoring
Catalyst in agent chamber is still in normal condition, without changing.Catalyst carries out multiple in synthesis gas air inlet tube assembly
After replacing, the catalyst in major catalyst chamber is changed again after reaching the replacing construction of setting.According to different unstripped gas
Concentration, it is necessary to which the coking situation to the catalyst in cocatalyst chamber is tested, to determine specific replacing construction.
Due to reducing the replacing number of whole catalyst, the catalyst in cocatalyst chamber is only changed, due to auxiliary catalysis
The amount of catalyst in agent chamber only accounts for the less ratio of whole catalyst amount, therefore can reduce due to coking and caused catalyst
Replacing amount, simultaneously because reducing the replacing amount of catalyst, decrease the consumption of catalyst.
Due to mainly being changed to the catalyst in cocatalyst chamber, and it is that synthesis gas air inlet tube assembly is being taken out into shell
Changed after body, it is possible thereby to be effectively reduced the replacing construction of catalyst, be especially provided with synthesis gas air inlet pipe group
