In order to solve the sulfur poisoning problem of Mn based low-temperature denitration catalyst, Prof. Huang Bichun and others have selected Pr as a doping element based on the 'ion polarization theory', to improve the sulfur poisoning resistance of the catalyst. The relevant results show that Pr doping can not only improve the low-temperature SCR performance of the catalyst, but also significantly improve the sulfur resistance of the catalyst.

At the same time, Prof. Huang bichun and others carried out the research on the technology and equipment for adsorption and degradation of multiphase extract tail gas. Aiming at the problems of complex components, concentration fluctuation and variable flow rate of multi-phase extract tail gas treatment. Prof. Huang et al. have explored high-efficiency adsorption materials of multi-component volatile organic compounds and low-temperature catalytic oxidation degradation materials. They have developed a complete set of tail gas collection and purification treatment equipment, and have integrated an intelligent control system. A set of safe and efficient catalytic oxidation process system for gaseous organic pollutants has been produced
