Title: Yingshuo Wang and a Continuous Hydrothermal Method for Potassium Humate Fertilizer

Introduction

Yingshuo Wang is an inventor associated with China University of Petroleum (East China) in Qingdao, China. His listed patent concerns a process for producing potassium humate fertilizer from potassium feldspar using continuous high-pressure hydrothermal treatment.

Latest Patents

Wang is associated with 1 patent: “Production Method for Preparing Potassium Humate Fertilizer from Potassium Feldspar Through Continuous High-Pressure Hydrothermal Method.” The disclosure describes wet grinding potassium feldspar into a slurry, followed by hydrothermal reaction, flash evaporation, and filter pressing. It then uses the resulting materials to prepare humic-acid-modified potassium and silicon-calcium fertilizers.

In the process, high-pressure tubular hydrothermal treatment and tower-type delayed reactions produce potassium aluminosilicate and potassium silicate. The alkaline potassium aluminosilicate residue is combined with humic acid, modified, granulated, and dried to make a humic-acid-coated slow-release potassium fertilizer. The potassium silicate filtrate is causticized with lime to produce potassium hydroxide solution, which is recycled into the wet-grinding stage. Alkaline calcium silicate is also combined with humic acid and processed into a coated slow-release silicon-calcium fertilizer.

Career Highlights

The patent presents an integrated approach to processing potassium feldspar into fertilizer products. Its described steps include recycling potassium hydroxide solution and producing both potassium fertilizer and silicon-calcium fertilizer from the reaction outputs.

Collaborations

Wang’s listed coworkers include Yuanyu Tian and Yiliang Tian. The supplied information does not specify their individual roles in the patent or the project.

Conclusion

Yingshuo Wang’s listed invention focuses on continuous hydrothermal processing of potassium feldspar to produce humic-acid-modified fertilizers and recycle potassium hydroxide within the process.
