Ternary catalytic resource treatment background introduction:
Ternary catalysis is a kind of catalyst composed of platinum,
palladium and rhodium, which has been widely used in automobile
exhaust treatment. However, the recycling rate of these precious
metals is not high, resulting in resource waste and environmental
pollution problems.
Three-way catalytic recovery scheme:
1. Catalyst separation The waste ternary catalyst is separated and
the part containing precious metals is recovered. This step
requires separation using chemical methods. 2. Extraction of
precious metals
The separated parts containing precious metals are extracted.
Platinum, palladium and rhodium can be extracted by electrolysis,
reduction and other methods. 3. Secondary use
The extracted precious metals are re-added to the newly produced
three-way catalyst. This can reduce production costs and reduce the
consumption of natural resources.
Process flow:
Equipment Overview:
Equipment 1: DC plasma arc furnace; Equipment 2: AC melting arc
furnace;
It is mainly used for the melting treatment of ternary catalysts or
slag containing precious metals, using arc to heat the precious
metal catalyst or slag to the melting temperature, by adding
silica, limestone, ferrosilicon, etc., to maximize the recovery of
precious metals.
1. Saving resources: By recycling the precious metals in the
ternary catalyst and slag, it can be reduced
Less consumption of natural resources. 2. Reduce costs: secondary
use of extracted precious metals can reduce production costs. 3.
Reduce pollution: Recycling precious metals in waste catalysts can
reduce environmental pollution
Dye.
