The Secret of Green Tokyo Olympics

The Tokyo Olympic Games, held one year late, have made many sports fans look forward to it for a long time, and the materials used to implement the principle of 3R hosting the Olympic Games are even more refreshing. Such as p polyurethane weightlifting equipment, running track, recycled plastic podium, etc. The green organic synthesis of these materials is inseparable from catalytic hydrogenation technology. Precious metal catalysts with high catalytic activity are generally used in catalytic hydrogenation technology, such as palladium carbon catalyst and Raney® nickel catalyst, which is the largest investment in hydrogenation unit.

On the one hand, the separation of catalyst after reaction is closely related to product quality. On the other hand, the recovery and reuse of precious metal catalyst can also save a lot of production costs for enterprises. Therefore, it is particularly critical to select a catalyst filtration and separation system with excellent performance.

For example, the new catalyst filtration and separation system designed and manufactured by Shinkai uses sintered metal filters as precision filter elements, which ensure 100% catalyst filtration and interception.

To obtain high-quality porous metal filters, Shinkai monitored the whole production process. And the excellent filtration equipment designed and manufactured by Shinkai is very suitable for the complete separation of various precious metal catalysts from mother liquor in fine chemical production. The filter’s process is simple to operate, easy to maintain, high temperature or solvents or corrosion resistance, with better strength, high precision, and can provide reliable and long-lasting filtration capabilities. In addition, Shinkai can design a filtration system to meet the continuous automatic production requirements of product filtration, catalyst application and withdrawal according to the service conditions and special requirements.

Shinkai’s new catalyst filtration and separation system has been successfully applied in the following production processes:

1. Dyes
C acid, 6-Chloro-m-toluidine-4-sulfonic acid, 3-amino-6-chlorotoluene-4-sulfonic acid, 5-amino-2-chlorotoluene-4-sulfonic acid, etc.;
