China has experienced dramatic economic growth over the past three decades, accompanied by an annual growth rate of energy consumption as high as 10%. It has become the world’s second largest energy consumer after the United States. Energy consumption, especially fossil fuel consumption, is the main source of anthropogenic air pollution emissions in Chinese cities. Nitric oxides (NOx), originating from the combustion of fossil fuels, is becoming one of the main air pollutants. Considering the significant impact of NOx emissions on regional air quality, i.e., formations of ozone and fine particles and contribution to acid deposition, there is an urgent need to control NOx emissions in China. In this regard, China has put into effect new regulations on NOx emission control. However, commercially available technologies for NOx removal are associated with several problems, such as high cost, tendency to form secondary pollutants, and low removal efficiency. Research and development of new-generation NOx removal technologies are of growing interest of both academia and industry.
This talk will begin with an introduction on the status of NOx emissions, control, and regulations in China. An overview of existing and emerging technologies for NOx removal from fossil fuel combustion flue gas will also be presented. Dr. Jing will then introduce the related R&D activities in her group with deliberation on the development of a novel chemical absorption - biological reduction integrated process for low cost, high efficiency removal of NOx from combustion sources.
About speaker: Guohua Jing is a full professor at Huaqiao University, China. She received her PhD in Chemical Engineering from Zhejiang University. Her research interests relate to new principles and technologies for energy and environmental applications with a focus on new materials and bio-processes for energy-related gas pollutant control. Guohua joined the ISGS as a visiting research scholar, effective on August 1. She is currently working with the Applied Research Lab (ARL) staff to conduct research on the modeling and evaluation of new systems and materials for carbon capture and multi-pollutant control associated with fossil fuel combustion.
