Problems solved by technology

[0012] Dispersions known today do not always meet all criteria
They may have, for example, good dispersibility but insufficient stability, especially when they are introduced into fuels containing fatty acid methyl ester fuels or other easily oxidizable plant sources
These dispersions may be sufficiently stable but may be catalytically active at too high a metal concentration to be economically desirable
However, as pointed out earlier, so these dispersions should have limited influence on the operation of fuel nozzles, leading in particular to limited contamination of the latter, even in the presence of biofuel-containing fuels or further metal-containing fuels
Further the presence of FBC in the fuel may lead to a reduction in the oxidation resistance of the fuel, especially when it contains biofuels

Embodiment 1

[0361] Example 1: Preparation of Dispersion

[0362] Dispersion 1A

[0363] Preparation of iron precursor solution

[0364] 1L solution was prepared in the following way: 576g Fe(NO 3 ) 3 with 99.4g FeCl 2 ,4H 2 O mix. The mixture was supplemented with distilled water to obtain 1 L of solution. The final concentration of this solution of iron precursor is 1.5mol.L -1 Fe.

[0365] Preparation of aqueous soda solution

[0366] 6mol.L -1 The NaOH solution was prepared in the following manner: 240 g of soda flakes were diluted in distilled water to obtain 1 L of solution.

[0367] In a 1L reactor equipped with a stirring system, the bottom of the kettle includes 400mL of 3mol.L -1 NaNO 3 solution. Adjust the pH of the solution to 11 with a few drops of 6 mol / L soda. Precipitate formation was achieved by simultaneously adding the previously prepared iron precursor solution and soda solution. The addition flow rate of these reactants was adjusted so as to keep t...

Abstract

The present invention relates to a composition comprising an additive in the form of an organic dispersion of iron particles in crystalline form for aiding particle filter regeneration and a detergent comprising a quaternary ammonium salt.

Description

technical field [0001] The present invention relates to the combination of an organic dispersion of iron particles and a detergent in a composition used as a fuel additive for internal combustion engines. Background technique [0002] During the combustion of fuel, especially diesel oil (gas oil) in an engine, carbonaceous products tend to form carbonaceous particles, which will be referred to as "soot" in the following specification, and soot is said to be harmful to the environment and health are harmful. Technologies that can reduce these soot emissions have been studied for a long time. [0003] A satisfactory solution consists in introducing a particle filter (or PF in the following) into the discharge pipe, capable of trapping soot in its passage to allow the gas to escape without any soot. When a certain amount of accumulated soot is obtained in the PF, the soot is burned to clear the passage of the PF. This step of regenerating the PF is usually carried out at a t...
