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.
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 complete set of equipment not only solves the industrial method of composite graphene liquid phase method to the activated carbon material used for supercapacitor, but also can activate the activated carbon material twice at room temperature.
The complete set of equipment meets the requirements of cleaner production.https://www.dxdcarbon.com/product-category/coconut-shell-activated-carbon
Chapter 2: The quality of graphene prepared by this project is guaranteed.
Self-made graphene has a high single-layer rate (up to 99%), fewer defects, and can be dried for a long time.
Can be prepared into a variety of solutions to facilitate the composite with other materials.https://www.activated-carbon-pellets.com/
Raw material is a wide range of natural graphite meters, is prepared by industrial methods can be put into production.In the experiment of adsorption eqThe optimum specific surface area of activated carbon prepared by physical activation method is 924.48m'/g, and the yield is 26.18%.
The optimum specific surface area of activated carbon prepared by chemical activation method is 1200.04 m2g, and the yield is 34%.
Although the specific surface area and yield of the chemical activation method are the largest, it can be seen that the activated carbon prepared by the physical activation method has higher economic benefit and environmental protection value considering the economic benefit and environmental protection value of the preparation process comprehensively.
Finally, based on the preparation of activated carbon from biomass, the adsorption equilibrium and kinetics of the prepared activated carbon for methylene blue and the adsorption characteristics of mercury in flue gas were studied.
The theoretical basis for its application in printing and dyeing wastewater treatment and mercury removal from flue gas is given.The reaction after adsorption for 20min belongs to the Lagergren quasi-second order reaction.
