Description
Technical field
The present invention relates to the biological scavenging solution preparation method of a kind of automobile three-way catalysts carbon distribution being convenient to store, belong to biological environmental production field.
Background technology
Ternary catalyzing unit poison deactivation and blocking are the most FAQs of current environment-protective motor.Each system of environment-protective motor is all around ensureing this central task of ternary catalyzing unit transformation efficiency to greatest extent, ternary catalyzing unit is once poison deactivation and blocking, transformation efficiency is just without collateral security, environment-protective motor just cannot normally work, and therefore ternary catalyzing unit maintenance problem is the central task of environment-protective motor maintenance.
Carbon distribution be engine in the course of the work, the material of a kind of deadlocked shape that unsaturated olefin and colloid produce at high operating temperatures in fuel oil.Cause ternary catalyzing unit to lose efficacy for coking deactivation because carbon deposit covers three-way catalyst and coatingsurface, cover carbon distribution a kind of mixture containing multiple elements such as carbon, hydrogen, sulphur, nitrogen, oxygen, heavy metals often of coatingsurface, coking deactivation is the one of the main reasons causing ternary catalyzing unit to lose efficacy at present.
The organic solvent that the many employings of existing ternary catalyzing unit clean-out system are a large amount of, while decarbonizing poor effect, produces detrimentally affect to operator and environment.Therefore biological species clean-out system becomes good research direction, but the biologically active substance very easily inactivation in biological species clean-out system, therefore, needs to adopt suitable method to make clean-out system not easy in inactivation and be convenient to store.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of just with storage, easy to use, utilize that biologically active substance is degraded, the biological scavenging solution of the automobile three-way catalysts carbon distribution of decarbonizing.
For solving above technical problem, the technical solution used in the present invention is the biological scavenging solution preparation method of a kind of automobile three-way catalysts carbon distribution being convenient to store, and comprises the following steps:
