Expanded graphite is an excellent adsorbent, especially it has a loose porous structure and has a strong adsorption capacity for organic compounds. 1g of expanded graphite can absorb 80g of oil, so expanded graphite is designed as a variety of industrial oils and industrial oils. adsorbent. The following Furuite graphite editor introduces the research on the adsorption of oil substances such as heavy oil by expanded graphite:
1. Expanded graphite is used as a new type of adsorbent due to the large number of pores on the analysis surface.
The expanded graphite worms mesh with each other, forming more surface pores, which is conducive to the adsorption of macromolecular substances, showing a large adsorption capacity, which can solve the problem of oil and organic non-polar substances.
2. Expanded graphite is used as a new type of adsorbent due to the large internal mesh
Different from the adsorbents of other materials, the internal molecules of expanded graphite are mainly medium and large pores, and most of them are in a connected state, and the network connection between the lamellae is better. It has a very good effect on the adsorption of organic macromolecules of this heavy oil. Heavy oil molecules are easily accessible and diffuse quickly in their network until they fill the interconnected internal pores. Therefore, the adsorption effect of expanded graphite is better.
Due to the loose and porous structure of expanded graphite, they have a good adsorption effect on some oil pollution and gas pollution, which makes it widely used in the field of environmental protection.
