Description

Technical Field

[0001] The utility model relates to the technical field of precious metal catalysts, in particular to a jacketed reaction device for precious metal catalysts. Background Art

[0002] Precious metal catalysts are precious metal materials that can change the rate of chemical reactions without participating in the final reaction products. Almost all precious metals can be used as catalysts, but commonly used ones are platinum, palladium, rhodium, silver, ruthenium, etc. Among them, platinum and rhodium are the most widely used. Their electron orbits are not filled, and reactants are easily adsorbed on the surface with moderate strength, which is conducive to the formation of intermediate "active compounds" and has high catalytic activity. At the same time, they also have comprehensive excellent properties such as high temperature resistance, oxidation resistance, and corrosion resistance, making them the most important catalyst materials.

[0003] Chinese Patent: Circulating Reflux Precious Metal Catalyst Reactor, Authorization Announcement No.: CN205635724U, Authorization Announcement Date: October 12, 2016, the solution circulation method is used instead of mechanical stirring or pneumatic stirring to improve the leaching rate of the precious metal catalyst material and the uniformity of the leaching. However, there is a problem that the production is usually fixed in one position during work. When the precious metal catalyst is produced, it is discharged through the discharge valve. When the solution leaks from the valve, the ground will be polluted, which will then cause the solution to be wasted, thereby increasing the production cost. Utility Model Content
