The project “Application of Rare Earth Nanocatalysts in Catalytic Combustion, Energy Conservation, and Environmental Purification†jointly undertaken by the Baotou Research Institute of Reef National Engineering Research Center Wet Chemical Engineering Laboratory and Tsinghua University has recently passed the technology organized by Baotou Science and Technology Bureau. The appraisal indicates that the study has taken a key step toward industrialization.
According to reports, the project utilized Tsinghua University's technological advantages in the manufacture of nanomaterials, catalyst preparation, catalytic combustion agents, and industrial exhaust gas purification applications, combined with research conditions of existing rare earth application technologies of the Baotou Rare Earth Research Institute, and developed civil and The industrial exhaust gas purification catalyst product can solve the problem of air pollution caused by residual organic matters in the gas, fuel oil and coal-fired processes, and can also solve vehicle exhaust pollution problems. After the successful development of its product and combustion purification device, it can be put into industrial production.
The researchers used co-precipitation-spray drying-calcination technology rare earth composite oxide catalyst, the specific surface area of ​​50 ~ 60 square meters / gram. The rare earth complex oxide catalyst synthesized in this project catalyzes the combustion of CO with a light-off temperature of 40°C and a complete conversion temperature of 120°C. The rare earth catalyst can be used in gas pipelines for gas pipelines, which can save energy by more than 20%. After the coal furnace flue is treated with a catalyst-driven screen, the CO in the flue gas can be completely purified, and other harmful substances in the exhaust gas can be reduced by more than 80%. .
