Activity of activated alumina and selectivity of catalyst

The main indicators to characterize the activity of activated alumina include the pore volume and specific surface area. When these two parameters are large, the activity is generally considered as high. The people pay more attention to the activity. In general, the preparation of raw materials, proportion of raw materials during the forming, selection of assistants, forming process, drying and activation roasting process are strictly controlled, so as to ensure and improve the activity of activated alumina,

Generally speaking, how long can activated alumina balls be used?

Many industrial products have a long service life, so how long can activated alumina balls be used? Some people say that it can be used for 1-2 years, some people say that it can be used for 7-8 years, and some people say that it can be used for 10 years, so how long can it be used? The following activated alumina manufacturers give you a brief introduction. Activated alumina manufacturers think that activated alumina balls are white spherical porous particles.

Introduce the properties of activated alumina balls in detail

What are the properties of activated alumina balls? Activated alumina balls have the following advantages in terms of raw materials: increase the density of the green body and reduce the water content and porosity. The following is a detailed introduction to the six physical properties of activated alumina balls. In fertilizer industry and petrochemical industry, it can be used as catalyst and catalyst carrier.

Do you know what the function of ozone catalyst is?

The process of ozone catalyst is based on the high-efficiency water treatment technology of ozone. The treatment process is simplified, and there is almost no secondary pollution. The ozone catalyst combines the strong oxidation of ozone and the adsorption and catalytic properties of the catalyst, which can effectively deal with the problem of incomplete degradation of organic matter. Ozone can immediately oxidize the remaining molecular chaperones, long chains, and some non-biodegradable organic compounds in sewage into carbon dioxide and water.

Analysis on the use performance of activated alumina

Activated alumina shape and application work Solid adsorbents are used in the reactor with different particle shapes. In the early stage, the adsorbents did not pay attention to the shape, and often only crushed large pieces of material, and then screened out uneven particle size and irregular shape. particle usage. Due to the indeterminate shape, the airflow distribution is very uneven during use, and the adsorption reaction is affected.

Talk about the properties of activated alumina balls

High-performance modern clear water activated alumina can bring the following benefits in the batching of amorphous refractories: improve the density, fluidity, strength of the green body, increase the amount of secondary mullite, etc., and reduce the amount of water added and porosity. In addition, activated alumina can also be used as adsorbent and desiccant, with large water absorption, fast drying speed, regeneration (400-500K baking) and water absorption without swelling, cracking and deformation.
