activated alumina vs activated carbon

When the heat treatment  temperature was 750��, the diffraction peak of ��-Al2O3  weakened or basically disappeared, and obvious ��-Al2O3 characteristic peaks appeared at 25.9, 35.2, 37.8, 43.4 and 57.5��, so ��-Al2O3 with fairly complete crystal was mainly produced at 750��. The reason can be explained from the prospective of Al(OH)3 phase transition and ablation samples. Powder, Granular & Extruded form. After being dried at room temperature for 12h, the samples were dried in the drying oven at 110 ��. When the calcination temperature was 450��, the remaining crystal water in pseudo boehmite was completely lost and ��-Al2O3 under transition form was generated with obvious diffraction peaks at 46�� and 66.8��; when the heat treatment temperature rose to 650��, characteristic diffraction peak of ��-Al2O3 strengthened continuously. 4 and 5, the sample had dual pore size distribution that mainly includes micropore and  mespore, which was  good for  formaldehyde adsorption. Fig.6 clearly showed that the formaldehyde adsorption capacity of the sample was excellent, and it was superior to that of pure activated carbon or activated alumina. 0.50g each of the sample, activated alumina and activated carbon were weighed respectively, and then placed into different weighing bottles which were placed into the air-tight drier full of saturated formaldehyde vapor. composite material was excellent, much better than that of the pure activated carbon Business Category: Activated Carbon Equipment, Activated Carbon Manufacterer, Activated Carbon Manufacturers, Bead Activated Carbon, China Long Business Description: Our company is located in Zhengzhou, Henan, China Gongyi City, our factory is the development, production, processing and sales of personal-owned enterprises, strong technical force, excellent equipment, advanced technology.

As one kind of porous inorganic solid materials with large specific surface area, activated alumina is one kind of fine adsorbent, catalyst and catalyst carrier. There are three main forms such as Granular Activated Carbon, Powder Activated Carbon, Extruded Activated Carbon. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. Presently, researches on the formaldehyde adsorption mainly focus on the activated carbon base materials; activated alumina studiers mainly focus on the catalyst carrier and water treatment, and there are few literatures on air purification. 1. SINOCATA offer the Fine Pore Silica Gel, Wide Pore Silica Gel, FNG Silica Gel, Alumina Silica Gel with different pore size and function such as water proof silica gels. Formaldehyde is one of the main pollutants of indoor air, and has such characteristics as extensive source, high toxicity, and long pollution time and so forth. H2O served as the precipitant, and aluminum hydroxide was prepared with alkaline precipitation method. When charcoal is activated, it is processed in a way to increase the porosity. For example, hydrogen desulfurization of residual oil and demetallization require proper surface area and distribution of macro- and micro-pore in some proportion; hydrogen denitrogenation catalyst is required to even load high metal content, high specific  surface  area,  large  pore  volume  and  the proper proportion of mesopore and micropores.

The product appearance is also white, which is difficult to distinct good and bad, but after the use of six months , bad activated alumina will be powdered, and plug the device and result losses. Mespore could play the channel role during formaldehyde adsorption and make the formaldehyde gas enter into the inner surface in a faster way. Activated Alumina ball is mainly used in chemical, metallurgy, electronics, oil and other industrial gases such as dehydration dry air, oxygen, nitrogen and other permanent gases smelting gas and petroleum cracking gas. This is a result of the production process and the spherical form of the grains. Like the name implies, Bone Char is actually the remains of animal bones that have been crushed, exposed to high furnace temperatures and carbonised. The experimental optimal heat treatment temperature of the sample was 450��. The results showed that The procedure for impregnation is described below. As one kind of porous inorganic solid materials with large specific surface area, activated alumina is one kind of fine adsorbent, catalyst and catalyst carrier. 0.50g each of the sample, activated alumina and activated carbon were weighed respectively, and then placed into different weighing bottles which were placed into the air-tight drier full of saturated formaldehyde vapor. The process was as follows. Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. The produced Al(OH)3  precipitation was dried in a drying oven at 120��, and passed the 100 mesh sieve after ball milling for 6h. Fig. Acting like a sponge in water, the moisture within the air will stick to the Alumina as it passes through. The most commonly-used adsorbent is activated carbon—a substance which is quite similar to common charcoal. General Carbon GC PPA12 Activated Alumina Specifications. Activated alumina is made out of aluminum oxide that is highly porous, while molecular sieve is made out crystalline metal aluminum-silicates. Specific surface area of samples was determined with automatic specific surface area and porosity analyzer. INTRODUCTION Fig.6 shows the formaldehyde adsorption effects of sample, pure activated carbon and activated alumina under different time. Because of lower calcination  temperature and shorter heat treatment process, aluminum hydroxide could only remove some of the crystal water and pseudo boehmite containing very less crystal water was produced.

At the same time, there was slight offsetting, indicating that  the ��-Al2O3 content increased, and crystallographic form turned much better. Activated carbon, also called activated charcoal, is a form of carbon has very large surface area, which are available for adsorption or chemical reactions. Specific surface area of samples was determined with automatic specific surface area and porosity analyzer. Because of this, activated carbon will have a large surface area, which can adsorb substances effectively. When the heat treatment temperature was above 650��, oxidation loss of activated carbon and secondary pore enlarging under high temperature caused significant reduction of specific surface area of the activated carbon. The attrition and crushing values for spheres are well adapted to their applications, the spherical form making possible homogeneous and compact loading with very little subsequent settling. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. 2.
