L'agent de décoloration de gazole décrit par l'invention présente une courte période de production et un faible coût.

La 1ere phrase en gras indique que c'est tout de même assez complexe chimiquement...
L'acide chlorhydrique sert à quoi?

Et le formaldéhyde ça se trouve où? (à part dans les meubles ikea? ) ?

La méthode de filtration multiple me semble bien laborieuse si on veut des volumes conséquents...une décoloration aux UV est bien plus facile et performante ! On avait un autre sujet là dessus...

[Christophe]

Une méthode chimique trouvée plus haut dans un brevet..de 3 pages avec les revendications ! Ca devrait être assez simple donc pour les motivés à mettre en œuvre : acide chloridrique et formladehyde !

Description

A kind of diesel decoloring agent and preparation method thereof and decoloration process Technical field The invention belongs to the decolorising agent field of oil product deep processing, be specifically related to a kind of efficient diesel decoloring agent, and preparation Method and decoloration process.

Background technology

Crude quality owing to being exploited is relatively low, containing heterocyclic compound in the diesel oil that refining produces, and olefin(e) compound etc. Unstable material, it causes the stability of diesel oil poor, after placing a period of time, its color burn blackening, affect the quality of oil product, And in use equipment and environment are worked the mischief, therefore improve diesel oil colourity and stability becomes most important.
In the research of diesel decoloration, CN 101311250A discloses the discoloration method of a kind of physical absorption, its decolorising agent by FeCl3、ZnCl2、AlCl3、 CuCl2, activated carbon, the composition such as kieselguhr, decolorising agent and diesel oil mix and blend at a certain temperature Decolour.CN 101475829A discloses a kind of high-efficiency decolorant, and its decolorising agent is mixed by a certain percentage by sulphuric acid and formaldehyde Composition, joins decolorising agent and carries out oxidative decoloration in diesel oil.CN 101735850A discloses a kind of diesel oil decolorized refining agent, Its refining agent is by CuO, ZnO, CuCl2、ZnCl2、CuSO4、ZnSO4Composition, joins decolorising agent in diesel oil, stirring and adsorbing, arrives Reach the purpose of decolouring.CN 101798520A discloses one and adds chloroazotic acid, cation exchange resin, peroxide in diesel oil successively Change hydrogen, the method adding heat decoloring.CN 104194820A announces one and is sequentially added into sulphuric acid, dehydrated alcohol, furfural in diesel oil The method of decolouring.
In above-mentioned diesel decoloration method, there is sulphuric acid relatively big to the corrosivity of equipment, slag yield is higher, extractant price Height, adds that thermal energy consumption is big, the high deficiency of processing cost.

Summary of the invention
It is an object of the invention to open a kind of efficient diesel decoloring agent and preparation method thereof and decoloration process, production technology letter Single, easy to use.It is added to refine in the black diesel obtained, decolouring can be reached, improve the purpose of stability.
A kind of diesel decoloring agent, it is characterised in that by 5%～15% sodium silicate, 2%～8% triethanolamine, 2%～8% 2 sub-second Base triamine, 1%～5%N, N-bis-(3-aminopropyl) lauryl amine, 1%～10% p-phenylenediamine, 2%～10% sodium hydroxide, remaining Amount water composition.
The preparation method of described diesel decoloring agent is: under agitation, successively by 5%～15% sodium silicate, 2%～8% 3 Ethanolamine, 2%～8% diethylenetriamines, 1%～5%N, N-bis-(3-aminopropyl) lauryl amine, 1%～10% p-phenylenediamine, 2%～10% sodium hydroxide is slowly added in excess water, temperature 30 DEG C～95 DEG C, is incubated 2h～5h, i.e. obtains this diesel decoloration Agent.
The decoloration process of described diesel decoloring agent is: add the pre-place that percentage by weight is 1%～5% in diesel oil to be decoloured Reason agent, stands after stirring reaction 5 min～40min, is filtrated to get supernatant and the black dregs of fat, adds then up and treat in clear liquid The decolorising agent of decolouring diesel oil percentage by weight 0.05%～0.5%, stands after stirring reaction 5 min～30min decolouring, is filtrated to get Oil product after decolouring, the black dregs of fat that the dregs of fat this filtered and pretreatment filtration obtain send hydrogenation plant to enter after washing Row reclaims refining.
Described pretreating agent by 70%～95% hydrochloric acid, 5%～30% formaldehyde form.
The present invention compared with prior art, has an advantage in that: the diesel decoloring agent preparation technology of the present invention is simple, produces week Phase is short, low cost, uses it for black diesel decoloration, and its decoloring reaction speed is fast, loss pollution-free, low, the black oil obtained Slag, after washing, is sent to hydrogenation plant and carries out reclaiming refining, and the diesel oil response rate is more than 98%.The diesel decoloring agent of the present invention is raw The product cycle is short, low cost.

Ce n'est pas vraiment prévu pour ça, mais il parait que ça fonctionne.
A essayer ...

[Christophe]

Je poste ça là, le Nord est actuellement victime d’une sévère pénurie de carburants :



Vous savez ce qu’il vous reste à faire si vous avez du mazout

[phil59]

Le litre de rouge est dans les 1.50€, donc pas très grosse différence avec le Go, actuellement.

Quand il y avait 50% d'écart, oui.

Ce n'était pas un secret, dans le temps, les agriculteurs, qui filtraient dans la terre, le rouge ....

[Christophe]

Il n'est pas question de commander du fioul rouge pour le décolorer mais d'en prélever dans sa cuve dans un contexte de pénurie...

[Macro]

Vous pourrez le decolorer autant que vous voudrez(ca c'est facile) le tracant restera ...et en cas de controle de douane (surtout toi Christophe a la frontiere belge) c'est jackpot ...

[Christophe]

Je suis pas en pénurie moi !

[sicetaitsimple]

le tracant restera ...et en cas de controle de douane (surtout toi Christophe a la frontiere belge) c'est jackpot ...

Je ne suis pas concerné (voiture essence), mais je me suis toujours demandé si ce genre de contrôle était en pratique effectué fréquemment sur des véhicules particuliers?
