Experimental Study on the Catalytic Oxidation of SO₂ by V₂O₅

Abstract

In order to achieve the catalytic oxidation of the low concentration SO2 flue gas in SNOX process, screen out the appropriate type of V2O5 catalyst for high-efficient transformation of the low concentration SO2. In order to provide foundation for reaction progression design, calculate the reaction depth of the process condition through the reaction thermodynamics analysis. According to the technological factors of affecting the effect of catalytic oxidation, investigate the reaction temperature, the space velocity and the mole ratio between O 2and SO2 on the SO2 transformation. Based on the experimental results, we did the reaction kinetics calculation. Above theoretical and experimental results provide the necessary technical parameters for designing catalystic oxidation of the low concentration SO2 in SNOX process.

Effect of Fiber Optic Plate on Centroid Locating Accuracy of Monocentric Imager

“…We use centroid method to solve the centroid location of the spatial target. The centroid method is a centroid location algorithm with the pixel intensity value as the weight [9,10]. Assuming that only one target is imaged on the sensor (see Figure 1), the intensity value of any pixel whose coordinate is (x , y ) on the image sensor is I (x , y ).…”
