Description
Technical field
The utility model is related to recycle zinc technical field, belong to a kind of device recycling zinc from dead catalyst containing zinc.
Background technology
In petroleum industry production, zinc system catalyst is one of most common catalyst, is widely used in low-temp low-pressure
Synthesizing methanol, synthesis ammonia and acetic acid second it is dilute synthesis it is medium.It is in addition this kind of since the usage amount of zinc system catalyst is very huge
Catalyst service life is shorter, causes the dead catalyst quantity being displaced very huge, and in the dead catalyst being displaced
Rich in a large amount of metallic zinc.Metal zinc recovering in dead catalyst is come out, dirt of the dead catalyst to environment can be not only reduced
Dye, and metallic zinc is allow to be recycled recycling.
The method of tradition recycling Metals from Spent Catalysts zinc is the acid-hatching of young eggs, and dead catalyst is mainly immersed in by this method
In acid solution, the metallic element in dead catalyst is leached by acid solution, is then separated by solid-liquid separation, evaporation calcining finally extracts useless
Zinc in catalyst.But in such method, since other most of metals in dead catalyst also are soluble in acid solution so that
Metallic element type is various in obtained leaching liquid, such as copper, iron, zinc, magnesium, aluminium, calcium, causes later separation purifying zinc process non-
It is often complicated.
It is, thus, sought for a kind of low cost, high benefit and leaching the good zinc extractive technique device of selectivity to solve
State problem.
