Data shows that China is the world's largest producer of alumina, with a production capacity of more than 43.5 million tons per year under construction and under construction, of which the production capacity for processing domestic bauxite is 32.5 million tons per year. In 2018, the national alumina output 48.96 million tons, making it the world's largest producer of alumina. The demand for alumina is also increasing year by year. So, what exactly is alumina?
Activated alumina is a porous adsorbent with high adsorption activity due to its large specific surface area, so it is widely used as a carrier for efficient adsorbents and various catalysts. Activated alumina not only has a large specific surface area, but also has great mechanical strength, physicochemical stability, high temperature resistance and corrosion resistance, but it is not suitable for operation under strong acid and alkali.
