Is the appearance of a sulfur-containing material was black, odorless, non-toxic, the internal pore structure developed. Large surface area, strong adsorption capacity of a class microcrystalline carbon materials, is a commonly used adsorbent. By the appearance of shape into charcoal: powdered, granular, irregular granular, cylindrical, spherical and fibrous. Sweetening activated carbon refers to the gasoline refining process, using activated carbon supported sulfonated titanium cyanocobalamin, for crude oil exceeded mercaptan removal, thus reducing the sulfur content of gasoline and improve quality. Meet the requirements of national environmental emissions. Features: ①, large surface area, high adsorption. As the load sulfonated titanium cyanocobalamin activated carbon adsorption requires methylene blue value to high, medium hole developed, load capacity than ordinary charcoal. ②, strength, non-friable. Since the load sulfonated titanium cobalt cyanide carbon, to be repeated in a fixed bed pressure to accept the challenge, the solution soak, it requires strength to be high, particles are preferably natural shape. ③, less ash desulfurization activated carbon impurities. In order to ensure the smooth progress of the chemical reaction catalyst, to minimize carbon in ash content of various impurities, metal ions. Improve the utilization of activated carbon pores. ④, desulfurization activated carbon water is low. Maintain the lowest possible moisture activated charcoal, to avoid affecting its functioning.
