Latest Patents

The supplied information lists one patent for Shen Gen Zhang: “Reduction and harmless method for recycling heavy metal waste.” The method processes heavy metal waste gypsum through smelting-flux preparation, lead smelting, fuming, and geopolymeric gelling. It directs sulfur-dioxide-containing smoke to an acid-making system, sends heavy-metal-bearing dust to a dedicated treatment system, and returns fuming dust to lead smelting. Secondary waste gypsum from acid production is recycled into smelting-flux preparation. The process aims to produce sulfuric acid and geopolymer material while reducing and treating the waste.

Career Highlights

Zhang’s listed patent focuses on integrating waste treatment with resource recovery. The described process connects several industrial stages to manage emissions and by-products while converting waste gypsum into useful outputs. The supplied data identifies the University of Science and Technology Beijing as his affiliated organization.

Collaborations

The supplied information names Bin Guo and De An Pan as Zhang’s coworkers. It does not specify their roles in the patent or the nature of their collaboration.

Conclusion

Shen Gen Zhang’s listed invention presents an integrated approach to reducing and treating heavy metal waste gypsum while recovering sulfuric acid and geopolymer material.
