Latest Patents

Younian Cao holds a patent for a method for the replacement of phosgene synthesis column catalyst. This invention discloses a method of quickly desorbing phosgene from a catalyst in a phosgene synthesizing tower when the catalyst is replaced. The process involves purging easily-desorbed phosgene with nitrogen gas, followed by ammonia gas, which reacts with the hardly-desorbed phosgene. The method ensures that the phosgene content at the outlet of the synthesizing tower is below 0.5 ppm. This innovation significantly reduces the time required for purging, decreases nitrogen gas consumption, and enhances operational safety.
