The iodine adsorption value, methylene blue adsorption value, strength and BET specific surface area of GAC were 1020.04mGG, 225mg/g, 88.73% and 1486.48m2/g respectively.
The experimental results show that the impregnation ratio and carbon activation temperature have great effects on the adsorption performance of GAC, while the kneading temperature and impregnation ratio have great effects on the strength of GAC.
Because the strength of GAC decreases with the increase of impregnation ratio, and the decrease range is large, so the preparation of GAC with compound activator is proposed.
The results show that the composite activator can reduce the impregnation ratio of phosphoric acid to wood chips and improve the strength of granular activated carbon.
At the same time, the composite activator can improve the adsorption performance of GAC.https://www.wyactivatedcarbon.com/
Therefore, granular activated carbon with good adsorption performance and high strength can be prepared by this method.Advantages of the project party's core technology
The first chapter of this project uses the company's own large number of preparation of dry storage, solution treatment of monolayer stone
Ink is a preparation method of graphene.
The raw material is commonly used graphite and common chemicals, easy to operate, easy to enlarge.
It solves the problem that graphene material is expensive and cannot enter the industrial application field without large-scale production.
It provides a foundation for the large-scale application of graphene.https://www.wyactivatedcarbon.com/products/powdered-activated-carbon/
Using the super conductivity and large specific surface area of graphene, the problem that the traditional activated carbon material used in the electrode can no longer improve the electric storage performance was solved.The economic structure has continued to improve. Innovation is playing an increasingly important role in underpinning development. The service sector accounts for a larger share of the economy, and consumption is contributing more to growth.
Stability is also reflected in new breakthroughs in reform and opening up.
terized by a steady but positive trend, and more positive changes have taken place in economic development.
