R&D Technology

Has imported the United States NOVA 2200e automatic surface area and porosity analyzer, British Malvern MS-2000 laser particle size analyzer, catalyst compression test – electronic universal testing machine, moisture analyzer, Phenom scanning electron microscopy, plastic, catalyst activity evaluation device and other research and development testing equipment.

Established innovation center and sophisticated R&D team, we currently have 2 external experts with the State Council allowance, 6 senior engineers and 10 researchers with Master Degree.

Have built solid cooperation with Germany Steinbeis-Transfer Center, Hefei University of Technology, Xi’an Thermal Power Research Institute, Chinese Academy of Sciences, Shanxi Institute of Coal Chemistry and other universities, research institutes.

By following testing on denitration catalyst’s surface shape, porosity distribution, catalyst activity, running resistance and tracking test of catalyst performance in different fields,We has created catalyst anti-clogging, anti-alkali metal poisoning and other performance enhancement technology.
