In the market, there are much activated alumina. However, everyone want to buy high quality activated alumina. How to distinguish high quality activated alumina?
In here, Shandong Bairui and Zibo Xiangrun will introduce how to distinguish high quality activated alumina.
To develop high-grade activated alumina (alumina adsorbent) products, people must firstly consider the production method and its cost. At present, many domestic factories can produce small quantities of high-end products, but due to high production methods and the high cost, affecting the enthusiasm of the production enterprises. How to distinguish high quality activated alumina. Whether there is the production of high-grade products without the need if too high input, which at a relative low cost to produce high-end products? Through the study in recent years that is possible. Sintering production of alumina manufacturers using carbonation to produce high-grade activated alumina (alumina adsorbent) and its hydrate — pseudo-boehmite and its active alumina products is entirely possible.
How to distinguish high quality activated alumina. In the process of producing activated alumina (alumina adsorbent) by carbonation, different concentrations of alumina hydrate can be prepared by changing the concentration, temperature, carbonation rate and controlling different end point pH value of sodium aluminate solution. Alumina hydrate with different characteristics can be used to prepare activated alumina carrier with different properties by adding different promotors and adopting different molding (spherical or strip) and activation process. (016 ~ 018ml / g), large specific surface area (250 ~ 350m2 / g), low reactor specific gravity class (012 ~ 016g / ml), small pore size (<40A) ), Medium diameter (40 ~ 100A) and large aperture (100 ~ 500A) and so on. (Na2O012 ~ 013%) and low sodium (Na2O <0.01%); high silicon type (SiO21% ~ 10%), high sodium (Na2O1% ~ 2%), ); Low iron type (Fe2O3 <01005%). At present, domestic alumina manufacturers are also developing and producing activated alumina (alumina adsorbent) and its raw materials to be boehmite, but at the initial stage, the future is still long way to go. Characterization of active alumina (alumina adsorbent) activity characteristics of the main indicators of pore volume, specific surface area. These two parameters are generally considered high activity. People have a high degree of attention to the degree of activity. Usually in the hole, macropores and their cross-linked several types.
How to distinguish high quality activated alumina. The pore structure required by different catalysts is different. Generally, the large pores of activated alumina (alumina adsorbent) are the channels involved in the reaction of the reaction substance into the catalyst, and the pores or mesopores with abundant surface area are the sites where the catalytic reaction takes place. Small holes or in the hole is usually the characteristics of raw materials with the first raw material preparation, molding the ratio of raw materials, additives selection, molding; and raw materials – such as drying and activation of roasting process and other aspects of strict control to ensure and improve Activity of activated alumina. And the selectivity of the catalyst is mainly related to its carrier. Therefore, when referring to the activity of activated alumina (alumina adsorbent), it is often mentioned that the selectivity of the catalyst with activated alumina as a carrier is also mentioned. Because the activity and selectivity of the catalyst are directly related to the carrier. The selectivity of the catalyst is directly related to the pore size distribution of the carrier, which is directly related to the pore size distribution. I produced the quartz sand filter, sponge iron oxygen scavenger is your good choice. Therefore, as the carrier of activated alumina (alumina adsorbent) must have a reasonable pore size distribution.
