The summary in English:

The invention discloses a diesel oil de-coloring agent as well as a preparation method and a de-coloring process thereof. The de-coloring agent is prepared from sodium silicate, triethanolamine, diethylenetriamine, N, N-di (3-aminopropyl) dodecylamine, p-phenylenediamine, sodium hydroxide and water. The de-coloring agent has a simple preparation process and is used for de-coloring diesel oil, and a used pre-treatment agent is composed of hydrochloric acid and formaldehyde. The diesel oil de-coloring agent disclosed by the invention is simple in preparation process, short in production period and low in cost and is used for de-coloring black diesel oil; a de-coloring reaction has a rapid speed, no pollution and low loss; and after obtained black oil dreg is washed with water, the black oil dreg is conveyed into a hydrogenation device so as to be recycled and refined, and the recovery rate of the diesel oil is 98% or more. The diesel oil de-coloring agent disclosed by the invention is short in production period and low in cost.

Public chat https://worldwide.espacenet.com/publica ... KC=A&FT=D# we can translate the summary into French:

The invention relates to a bleaching agent for diesel fuel as well as a method of preparation and a method of bleaching thereof. The bleaching agent is prepared from sodium silicate, triethanolamine, diethylenetriamine, N, N-di (3-aminopropyl) dodecylamine, p-phenylenediamine, sodium hydroxide and water. The bleaching agent has a simple preparation process and is used to bleach diesel oil, and a pretreatment agent used is composed of hydrochloric acid and formaldehyde. The diesel fuel bleaching agent described by the invention is a simple preparation process, a short production period and a low cost, and it is used to bleach black diesel fuel. a discoloration reaction at a rapid rate, no pollution and low losses; and after washing the black oil residue obtained with water, it is transferred to a hydrogenation device in order to be recycled and refined, and the recovery rate of diesel fuel is 98% or more. The diesel bleaching agent described by the invention has a short production period and low cost.


The first sentence in bold indicates that it is still quite complex chemically ...
What is hydrochloric acid used for?

And where is formaldehyde located? (apart from ikea furniture? : Mrgreen: )?

The multiple filtration method seems very laborious to me if you want large volumes...UV bleaching is much easier and more efficient! We had another topic on that...

Description

A kind of diesel decolorizing agent and preparation method thereof and decoloration process Technical field The invention belongs to the decolorizing 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 color and stability becomes most important.
In the research of diesel decoloration, CN 101311250A discloses the discoloration method of a kind of physical absorption, its decolorizing agent by FeCl3、ZnCl2、AlCl3、 CuCl2, activated carbon, the composition such as kieselguhr, decolorizing 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 sulfuric 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 decolorizing 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 on e and is sequentially added into sulfuric acid, dehydrated alcohol, furfural in diesel oil The method of decolouring.
In above-mentioned diesel decoloration method, there is sulfuric 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, decoloring can be reached, improve the purpose of stability.
A kind of diesel decoloring agent, it is characterized 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, ie 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 decolored 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 decolorizing 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%.

A liter of red is around 1.50€, so not a big difference with the Go, currently.

When there was a 50% difference, yes.

It was not a secret, in the old days, the farmers, who filtered in the earth, the red ....

It is not a question of ordering red fuel oil to discolor it but of taking some from your tank in a context of shortage... : Mrgreen:

You can bleach it as much as you want (that's easy) the tracer will remain ... and in case of customs control (especially you Christophe at the Belgian border) it's jackpot ...

I am not concerned (petrol car), but I have always wondered if this kind of control was in practice carried out frequently on particular vehicles?
