The Method of Adsorption with Activated Alumina Balls Production
A method of adsorption with activated alumina balls production involves the chemical alumina production process, the method with aluminium hydroxide as raw materials through crushing, rapid dehydration, granulating, hydration, activation of roasting, screening packaging process, the main technical characteristics, in the rapid dehydration process, flash calciner inlet temperature is 850-950 ℃, the outlet temperature control in 430-490 ℃. The formulation of the binder used in the pelletizing process is 100 parts water, 8-12 parts ammonium bicarbonate, 6-10 parts sodium carbonate and 40-60 parts alumina. In the hydration process of the pellets, the pellets are hydrated and then hydrated with steam, the temperature is 90-100℃, the time is 4-6 hours, and the roasting process is 390-430℃, and the roasting time is 30-40 minutes. The activated alumina ball made by using the process method of the invention has a specific surface of over 280m²/g.
Above, widely used in the petrochemical industry, especially in the purification of ethylene, butene and other chemical raw materials adsorption purification effect is very good, at the same time can effectively prevent butene monomer isomerization reaction.
