Embodiment 1
[0027] Present embodiment provides a kind of regeneration agent of three-way catalytic converter of gasoline vehicle, is made up of following raw material by mass percentage:
[0028] Chlorine-containing solvent 0.006~0.03%
[0029] Hydrogen peroxide 0.01~0.04%
[0030] Methanol solvent 99.96~99.954%
[0031] Among them, methanol adopts a methanol solvent with a concentration of 99.99%; the solvent containing chlorine elements can use chlorine-containing compounds, specifically hydrogen chloride, dichloropropane, dichloroethane, carbon tetrachloride and other chlorine-containing compounds. A sort of;
[0032] The hydrogen chloride and hydrogen peroxide in the above raw materials are added into the methanol solvent and mixed to obtain the regeneration agent for the three-way catalytic converter of gasoline vehicles.
[0033] The working principle of the regenerant is: after the regenerant enters the combustion chamber from the engine intake pipe for combustion, a high-temper...
Embodiment 2
[0036] The present embodiment provides a method for regenerating a three-way catalytic converter of a gasoline vehicle, which is a method for regenerating the three-way catalytic converter of a gasoline vehicle using the regenerant given in Example 1 above, the method comprising:
[0037] Adopt the regeneration agent that above-mentioned embodiment 1 provides, the regeneration agent is joined in the engine combustion chamber by the vacuum tube on the automobile engine intake manifold;
[0038] After the regenerant is burned in the engine, a high-temperature oxidation environment containing chloride ions is established in the exhaust system, and the high-temperature oxidation environment is used to remove poisons such as carbon deposits and sulfur-phosphorus chemical complexes covered on the three-way catalyst in the three-way catalyst;
[0039] For the three-way catalyst deactivated due to chlorine loss and crystal grain aggregation, the regenerant can disperse the aggregated a...
Embodiment 3
[0044] In this embodiment, the regeneration agent provided in the embodiment of the present invention is described to regenerate the three-way catalytic converter of the Jetta closed-loop EFI gasoline vehicle with the three-way catalytic converter installed:
[0045] The formula of used regeneration agent is, each raw material is by mass percentage:
[0046] Hydrogen chloride 0.01%
[0047] Hydrogen peroxide 0.02%
[0048] Methanol solvent 99.97%.
[0049] Use the Jetta closed-loop EFI gasoline car with a three-way catalytic converter installed, insert the hollow needle end of the infusion set into the rubber intake vacuum tube of the car engine, and input the regenerant of the above-mentioned formula of 750 milliliters (add the methanol solvent of hydrogen chloride and hydrogen peroxide) The regeneration agent formed), the engine runs at a speed of 1500 rpm, and the regeneration agent is sucked into the combustion chamber of the engine by the effect of atmospheric pressure,...
