A few days ago, through the selection of South China University of Technology, Yang Xiaobo, a graduate student jointly trained by our company and South China University of Technology, won the "2016 Outstanding Graduate Student in Professional Practice" and "Excellent Master Graduate Innovation Fund". Under the guidance of two master tutors, Wu Fan and Xia Qibin, student Yang Xiaobo actively explored the deactivation mechanism of arsenic-containing catalysts by consulting literature and scientific experiments in view of the use of denitrification catalysts in Northeast China, and solved the problem of regeneration of arsenic-containing deactivated catalysts. In addition, on the basis of the experimental research of the previous senior brothers and sisters, the small-scale research on the extraction of vanadium and tungsten from the waste SCR catalyst has been carried out, and positive results have been achieved, and the process of harmless treatment of the waste catalyst has a high practical value.
