Recovery of precious metal catalysts
Catalysts occupy an extremely important position in the modern chemical industry. According to statistics, about 80% to 85% of chemical production processes use catalysts to accelerate the reaction rate and increase production efficiency. However, expensive spent catalysts increase the cost of enterprises, and filter recycling. Inactivated spent catalysts have become inevitable, especially the recovery and reuse of metal catalysts is considerable.
Magnetic particles such as nickel, chromium, molybdenum, iron, and platinum are often present in the catalyst. Magnetic and non-magnetic particles can be separated by selective adsorption of a permanent magnet/electromagnetic filter, and the separation and design can be controlled by the design and adjustment of the magnetic field. The average particle size of the magnetic particles. The recovery of weak magnetic catalysts such as platinum and chromium is more suitable for electromagnetic filters. The electromagnetic filter has higher magnetic strength and can recover more than 1 um of impurities.
Successful Case
The user is a chemical company and needs to reform the original Raney nickel catalyst recovery process. Raney nickel has magnetic permeability and uses an electromagnetic filter. The recovery rate of the catalyst is more than 98% after field operation test.
