Description
Technical field
The present invention relates to remove the cleanser of volatile oxidn, belong to atmospheric pollution and purify neck
Territory, is specifically used for adsorbing MTP(preparing propylene from methanol) volatile oxidn is clean in tail gas
Agent and preparation method thereof.
Background technology
Global Oil resource is the deficientest, can constantly rise by crude oil extraction cost.It is former with crude oil
The propylene monomer of material is affected by cost and remains high, and new MTP technique is to be former with coal
Material produces the technique of propylene monomer, has reached good balance in terms of cost benefit.And China
Being again big coal country, coal resources relative abundance is more beneficial for new MTP technique propylene monomer
Production.Dopant species and quantity in the polymerization-grade propylene monomer that conventional petroleum route technique produces
Being relatively fixed, the polymerization-grade propylene monomer that MTP Coal Chemical Industry process route produces, owing to it is former
Material is methanol or dimethyl ether so that introduce substantial amounts of volatile oxidation in its propylene monomer produced
Thing impurity.Along with China becomes the first in the world big polypropylene manufacturing country and country of consumption, gather at propylene
In conjunction process, deep-processing process and laboratory analysis process, MTP technique the propylene produced
In tail gas, volatile oxidn produces safely threat to surrounding people, the most also environment is produced dirt
Dye.
Material benzenemethanol and the dimethyl ether of new MTP technique are relatively low to the toxicity of human body, but
Other volatile oxidn particularly aldehydes being converted into by it has severe toxicity to human body.With formaldehyde
As a example by, it is the gas of colourless irritant abnormal smells from the patient under usual state, 0.06 × 10-6mg/m3
During concentration, child just can cause asthma.0.1 × 10-6mg/m3During concentration, just can produce different
Taste and sense of discomfort.0.6 × 10-6mg/m3During concentration, just can stimulate eyes and throat, concentration
Vomiting and even pulmonary edema of panting is produced time higher.Reach 30 × 10-6mg/m3During concentration, people
Dead immediately.Therefore national environmental standard, the formaldehyde gas maximum permissible concentration in environment is
0.05×10-6mg/m3。
At present, the devolatility oxide process that domestic and international MTP tail gas uses mainly has wet type
Method and dry process, the oxide in gas is transferred in liquid phase by gas-liquid exchange by damp process,
Having the oxide removal capacity that comparison is high, the oxide in gas is inhaled by dry process by gas-solid exchange
It is attached in cleanser, has the oxide removal precision that comparison is high.Oxygen compound in damp process deolefination
United States Patent (USP) US4814517 of patent such as UOP (UOP), just using
Methanol in butane liquid phase separation C4 alkene and dimethyl ether.Oxygen compound in dry process deolefination
Patent such as Chinese patent CN101884905A disclose a kind of alkali metals modified 4A, 5A,
The method of ZSM-5 molecular sieve adsorption cleaning hydrocarbon material flow.The cleanser of oxide removal is applied
Depollution of environment field is owing to requiring oxide removal precision the highest, and domestic also do not have patent report.
