Activated alumina has good adsorption capacity, strong surface activity and excellent thermal stability, so it can be widely used. This aspect is closely related to the raw material composition of activated alumina. There are two kinds of raw materials for its production, one is "quick de powder" produced by gibbsite or Bayer stone, and the other is pseudo boehmite produced by aluminate or aluminum salt or both. Let's introduce the production of these two raw materials.
1, X- ρ Production of alumina
x- ρ Alumina is the main raw material for the production of activated alumina balls, which is referred to as FCA in foreign countries. In China, it is called "rapid dehydration" because it is aluminum oxide powder produced by rapid dehydration method. "Quick de pulverization" is x-alumina and ρ - The content of alumina mixture varies due to the difference of production conditions.
2, Metoda proizvodnje pseudo bemita
Aluminijev oksid monohidrat i aluminijev oksid trihidrat proizvedeni prirodno ili umjetno ne mogu se koristiti kao desikant, adsorbens, katalizator i nosač katalizatora zbog njihove male specifične površine, malog volumena pora i niske aktivnosti. Aluminijev oksid monohidrat ili aluminijev oksid trihidrat treba preraditi u pseudo bemit. Pseudobemit ima veliku specifičnu površinu, veliki volumen pora, veliku veličinu pora i visoku aktivnost. Pogodan je za upotrebu kao desikant, adsorbent, katalizator i nosač katalizatora u oblastima petrohemijske industrije, hemijskog đubriva i otpadnog gasa.
Gore navedeno je klasifikacija aktivnih sirovina od glinice. Samo kada pravilno rukujemo ova dva materijala možemo poboljšati njihov kvalitet, tako da imaju bolje rezultate u sintezi naših proizvoda.
