Latest Patents

Tiejun Chen holds a patent for a method of extracting vanadium from shale. This method involves several steps: first, grinding the shale into fine powders and mixing it with an additive in a mass ratio of 1:0.04-0.12. The mixture is then heated to a temperature between 850 and 950°C at a heating rate of 5-9°C/min, followed by baking for 30 to 90 minutes. The next steps include immersing the product in water and acid to yield two solutions, which are combined for ion exchange adsorption using a styrene-divinylbenzene based macroporous anion-exchange resin. Finally, the process concludes with desorption, purification, and precipitation to yield poly ammonium vanadate, which is calcined at a temperature between 450 and 530°C for 20 to 50 minutes to produce VO. Tiejun Chen has 1 patent to his name.
