Our company developed SZA series of new catalysts suitable for S Zorb process. SZA series catalyst adopts composite transition metal and its oxides as the active component, and the transition metal oxides and special fillers are combined as the carrier through adhesive to further load the transition metal and form desulfurization catalyst products. Compared with existing industrial catalysts, SZA desulfurization catalyst has stable skeleton structure and is not easy to wear. The content of zinc silicate is low, which reduces the agent consumption of the plant. The active metal dispersed evenly and improved the desulfurization activity.
