Abstract
A kind of preparation method of carrier provided by the invention and liquid phase antichlor comprising it, including the preparation method of carrier is to mix carrier substrate, pore creating material and binder, molding cures 6-18h at 20-40 DEG C of temperature；Roasting, obtains dechlorination agent carrier.After antichlor carrier impregnation is in active component, roasted to get to liquid phase antichlor.Liquid phase antichlor prepared by the present invention not only increases the mechanical strength of antichlor, and effectively raises the amount of processing raw material in the antichlor unit interval, and then improves the flux of antichlor.
Description
Technical field
The invention belongs to dechlorination technology fields, and in particular to a kind of preparation method of dechlorination agent carrier and the liquid phase comprising it
Antichlor.
Background technology
With the continuous development of petrochemical technology, the production process of petrochemicals is as reformed, adding hydrogen, cracking
Deng, and other chemical products manufacturing technologies such as hydrogen manufacturing, polymerization and carbonylation synthesis butanol, ethylene epoxy second
Energy-efficient new catalyst is all gradually used in alkane, ethylene glycol, low pressure methanol synthesis etc..But new catalyst pair
Raw material impurity content requires harshness than traditional catalyst, wherein more stringent requirements are proposed to chlorinity.On the other hand, with stone
The in poor quality increasingly of oily raw material and make being continuously increased for chlorine impurity content in raw material, and can cause seriously containing a large amount of chlorine impurity
Equipment corrosion, influence the stable operation of equipment.So most important to raw material dechlorination.The chlorosity of currently used antichlor exists
6-25%, universal grain size is in 3-5mm.Its preparation process mostly be will prepare carrier raw material mixed with active component after, be molded,
Antichlor is made after roasting, such preparation process can cause active component being unevenly distributed on carrier, and then influence de-
The dechlorination effect of chlorine agent.There is also the low problem of flux that dechlorination speed is antichlor slowly, this makes existing antichlor simultaneously
It is small in unit interval processing material quantity to obtain antichlor, and then extends the time of entire production technology, greatly increases and is manufactured into
This.Although the mechanical strength of current antichlor meets the standard (50N/cm) of the Ministry of Chemical Industry, is using in 30-100N/cm
In the process, especially when processing material quantity is larger, antichlor is easy crushing or argillization, and then greatly reduces the de- of antichlor
Chlorine effect.
Chinese patent CN1209355A discloses the preparation method of macropore alumina supporter, uses Aci-Jel solvent to quasi-
Boehmite carries out after peptization and peptization be 40-95 DEG C in temperature at cure 0.3-15h, after extruded moulding, with containing ammonium ion
Alkali compounds handled, it is dry and and roasting, obtain the macropore alumina supporter.Above-mentioned patent improves carrier
Mechanical strength, be that it can reach 150-250N/cm, specific surface area is also in 145-165m2/g.But to quasi- thin in above-mentioned patent
Diaspore has carried out acid-sol processing then and has carried out alkali process, however either acid-sol processing or alkali process, not only
The pore passage structure that carrier surface will be destroyed, reduces its specific surface area, reduces the ability of its load active component, and through acid and
Carrier after alkali process will produce a large amount of pollution exhaust gas in roasting process, cause great pollution to environment, and carry
Bronsted lowry acids and bases bronsted lowry on body surface face can not be removed all in roasting process, and the acid or alkali that remain on carrier can reduce carrier
The performance of the active component of upper load.The maturing process in above-mentioned patent is carried out before carrier is molded simultaneously, due to curing
Journey is the process of a deep reaction, and being cured before being molded can make powder viscosity become larger, and increases carrier and is molded difficulty, and also can shadow
Ring carrier intensity after molding.And the problem that patent disclosed above is uneven to the Active components distribution of antichlor and flux is low
There is no solutions.
Invention content
The technical problem to be solved in the present invention is to overcome that existing antichlor dechlorination rate is slow, Active components distribution is uneven
And the problem that mechanical strength is low, to provide, a kind of flux is high, active constituent is evenly distributed and the carrier of high mechanical strength
Preparation method and liquid phase antichlor comprising it.
For this purpose, technical solution used by the present invention realizes above-mentioned purpose is as follows：
A kind of preparation method of dechlorination agent carrier, includes the following steps：
(1) carrier substrate, pore creating material and binder are mixed, molding obtains support precursor；
(2) by the support precursor at 20-40 DEG C of temperature, 6-18h is cured；
(3) support precursor after curing is roasted, the dechlorination agent carrier is obtained.
Preferably, in the preparation method, in the step (1), the pore creating material is carbon dust, starch, sesbania powder
One or more of with cane sugar powder.
Preferably, in the preparation method, in the step (1), the carrier substrate is aluminium oxide, aluminium hydroxide
One or more of with boehmite.
Preferably, in the preparation method, in the step (1), the binder is in CMC, Aluminum sol and water
One or more.
Preferably, in the preparation method, in the step (3), the temperature of the roasting is 300-600 DEG C, when
Between be 2-4h.
Preferably, in the preparation method, the carrier substrate, the pore creating material and the binder mass ratio
For：(50-80)：(1-10)：(5-40).
Preferably, in the preparation method, in the step (1), the grain size of the support precursor is 3-6mm,
Shape is spherical shape.
A kind of liquid phase antichlor, including the dechlorination agent carrier and the activearm that is supported on the dechlorination agent carrier
Point, the active component is selected from one or more of the oxide of IA, IIA and IIB, and the active component accounts for the antichlor
The 10-25% of gross mass.
Preferably, in the liquid phase antichlor, the active component is the oxide of potassium.
A method of the antichlor is prepared, is included the following steps：
The solution for preparing one or more of soluble-salt containing IA, IIA and IIB, by any institutes of claim 1-7
The antichlor carrier impregnation stated is dry in the solution, and roasting obtains the liquid phase antichlor；
Wherein, the temperature of the drying is 50-120 DEG C；
The calcination temperature is 200-700 DEG C, time 2-4h.
Technical solution of the present invention has the following advantages that：
1. the present invention provides a kind of preparation methods of dechlorination agent carrier, it is preferred that emphasis is first by carrier substrate, pore creating material and
After binder mixed-forming, using being roasted after the step of curing, make to be formed inside carrier substrate during curing
According to stable structure, and then the mechanical strength of carrier is greatly improved after being roasted, and is omitted in the present invention
The step of acid-sol processing and alkali process, technique is not only simplified, cost has been saved, avoided acid-sol and handle and alkali process
After carrier, carrier a large amount of polluted gas is discharged in roasting process and the problem of, and be effectively improved dechlorination agent carrier
With the binding ability of active component, and then the amount of the carrier loaded active component of antichlor is increased, to improve by above-mentioned de-
