Activated alumina, also known as activated alumina, is usually referred to as "activated alumina" which uses alumina in the catalyst. It is a porous, high-dispersion solid material with a large surface area and micropores. The surface has the characteristics required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used as a catalyst and catalyst carrier for chemical reactions. Spherical activated alumina pressure swing oil adsorbent is white spherical porous particles. The activated alumina has uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, does not swell or crack after absorbing water, and remains in its original state, non-toxic, odorless, and insoluble Water, ethanol. Activated alumina is a high-efficiency desiccant for deep drying of trace water, suitable for heat-free regeneration equipment.
Activated alumina belongs to the category of chemical alumina and is mainly used in adsorbents, water purifiers, catalysts and catalyst carriers. Activated alumina has selective adsorption capacity for gas, water vapor and some liquid moisture. After the adsorption is saturated, it can be revived by heating at about 175～315℃ to remove water. Adsorption and resurrection can be carried out multiple times. In addition to being used as a desiccant, it can also absorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc. It can also be used as a catalyst and a catalyst carrier and a chromatographic analysis carrier.
It can be used as a defluorinating agent for high-fluorine drinking water (large fluorine removal capacity), as a defluorinating agent for circulating alkanes in the production of alkylbenzene, as a deacidification regenerator for transformer oil, and as a gas drying agent in the oxygen industry, textile industry, and electronics industry. , Automatic instrument wind drying, as desiccant and purifying agent in chemical fertilizer, petrochemical drying and other industries (the dew point can reach -40℃), and the pressure swing adsorption dew point can reach -55℃ in the air separation industry. It is an efficient desiccant for deep drying of trace water. It is very suitable for non-heat regeneration devices.
Activated alumina has a large specific surface area, a variety of pore structures and pore size distribution, and rich surface properties. Therefore, it has a wide range of uses in adsorbents, catalysts and catalyst carriers.
Alumina for adsorbent and catalyst carrier is a fine chemical and also a special chemical. Different applications have different requirements for physical structure, which is the reason for its strong specificity and many varieties and grades. According to statistics, the amount of alumina used as catalysts and carriers is more than the total amount of catalysts used in molecular sieve, silica gel, activated carbon, diatomaceous earth and silica alumina gel. This shows the pivotal position of alumina in catalysts and carriers.
