Title: Qing Liu and an Advanced Catalyst for Landfill Leachate Treatment.

Introduction

Qing Liu is an inventor associated with Nanjing, China. Her work includes a patent for a catalyst designed to improve the treatment of landfill leachate and the removal of carbon- and nitrogen-based pollutants.

Latest Patents

Liu is associated with 1 patent: “Method for Preparing Amorphous Silica-Alumina Encapsulated Metal Oxide Catalyst and Application Thereof.” The invention describes preparing a catalyst by placing silica-alumina precursors inside the tunnels of a monometallic or bimetallic complex, followed by heat treatment.

The resulting catalyst is designed to disperse acidic sites and oxygen vacancies, provide a broad pore-size range, and support efficient mass transfer. These properties can improve cracking-oxidation tandem reactions used to purify landfill leachate. The patent reports COD removal of at least 98.3% and ammonia nitrogen removal of at least 98.0%. It also reports that the purified effluent has a COD concentration below 98.7 mg/L and an ammonia nitrogen concentration below 24.9 mg/L.

Career Highlights

Liu’s listed organizational affiliations include Nanjing Tech University and Nanjing Resources and Environment Engineering Technology Research Institute Co., Ltd. Her patent focuses on environmental protection and applies catalyst design to the treatment of complex wastewater.

Collaborations

Liu’s listed coworkers include Zhuxiu Zhang and Xu Qiao.

Conclusion

Qing Liu’s patented catalyst approach combines material design with wastewater treatment, aiming to improve the removal of pollutants from landfill leachate.
