Detailed Description
On the basis of the original inert ceramic ball, high temperature, high fever, high thermal shock resistance of high-quality refractory production Perforated ball, with good mechanical strength, high temperature (up to 1790 ° C) temperature-resistant, heat-resistantshock resistance, excellent acid and alkali chemical resistance, the ability of all inorganic and organic acids and strong alkaline substances such as sodium hydroxide solution, in addition to hydrogen fluoride. The products also have a suitable specific surface area and the higher the porosity. Compared with ordinary inert ceramic balls, a bulk porosity of 6-10%, 15-25% increase in the specific surface area. Openings Ciqiu than the larger the surface area, so that the contact reaction efficiency. Can reduce the weight of the bed, so that the purifier, the fluid in the reactor is uniformly distributed, uniform, highly efficient heat and mass transfer reaction, the reactants and the heat is concentrated to appear in the localized openings porcelain higher porosity, can accommodate adsorption of a variety of raw materials in the gas-liquid gum, coke, heavy metals and other solid particles of impurities, to prevent the running process to lead to catalyst poisoning due to carbon deposition. purpose of protect the catalyst inert alumina reaction tower used within a low pressure drop, reducing the resistance of the tower, to improve the mass transfer efficiency of the entire reaction tower has an important role to improve the yield, improve product quality. Inert alumina Perforated ball suitable for hydrogen production in the coal chemical industry, gas purification, a period of synthetic ammonia, Sec conversion furnace, deep processing of crude oil catalytic reforming, hydrogen, hydrogenation, catalytic cracking the proppant or protection as a catalyst agent under high temperature and high pressure environment.
