Problems solved by technology

[0004] For now, the problems that need to be further solved in the research of regenerative filters are: lowering the regeneration temperature and further reducing the energy required for regeneration
[0005] The research on additives for the regeneration of engine exhaust particulate traps is not long, mainly concentrated in some foreign companies such as INNOSPEC, PEUGEOT and INFINEUM, while domestic research on this aspect is basically blank

Abstract

The invention relates to a regenerated additive for a tail gas discharging particle collecting device of an engine of a diesel vehicle and a preparation thereof. The additive consists of different metallic compounds with two or more than two of La, Fe, Mn, a solvent and other assistant components. An iron compound is ferrocene with oil-solubility and a derivative thereof, accounting for 0.5-5.0 wt% of the additive; a manganese compound is manganese naphthenate and manganese acetate, accounting for 0.5-5.0 wt% of the additive; a lanthanide compound is lanthanum nitrate, accounting for 0.0-2.0 wt% of the additive; the other assistant components comprise 2, 6-ditert-butyl-ethyl phenol, accounting for 0.0-0.5 wt% of the additive; the solvent is alkylbenzene, long-chain alkane, short-chain aliphatic alcohol and a little of diesel fuel, and is used for completing the rest weight of the additive. The invention has the advantages that firstly, the regeneration temperature of the particle colleting device is obviously reduced after adding the additive, and the regeneration temperature is already close to the tail gas discharging temperature of the diesel engine; and secondly, the additive is effectively regenerated under the temperature of discharging gas of the diesel vehicle to reduce the energy consumption.

Description

technical field [0001] The invention relates to an additive used for regeneration of a diesel vehicle engine tail gas emission particle trapping device and a preparation method thereof. Background technique [0002] As countries around the world pay more and more attention to environmental pollution, more and more attention is being paid to pollution control, including the control of vehicle exhaust emissions. In order to eliminate particulate matter (particle material) emissions during the use of diesel vehicles, it is necessary to install a particulate filter behind the engine. The particulate trap consists of a particulate filter and a regeneration unit. The particulate filter traps the solid carbon particles in the exhaust of the diesel engine and the soot that absorbs the soluble organic components through the filter medium (filter element) with extremely small pores, thereby reducing the emission of particles. [0003] The particulate filter has a high filtration eff...
