The industrial and industrial production of graphene with low cost and large output can be completed, which will greatly promote the development of downstream industries.
Using graphene's remarkable physical and chemical properties, electrons can travel through graphene much faster than they can through silicon, creating more sensitive sensors, electronic components, displays, solar cells and hydrogen storage devices.
Pacific Northwest National Laboratory and Princeton University are working with a private company to develop a high-capacity, fast-charging battery.
The secret is to add graphene to lithium-ion batteries to improve power and cycle stability.https://www.dxdcarbon.com/
Researchers at Stanford University say graphene-based lighting could be cheap and environmentally friendly.
Graphene-based LECs could replace metal-based OLEDs(organic light-emitting diodes). They could also replace traditional metal-based graphite electrodes in lamps, making them cheaper and easier to recycle.As one of the means of harmless waste treatment, incineration method can quickly realize the reduction of waste, harmless and recycling, so it has been more and more widely used in China.
In the process of waste incineration, toxic organic compounds such as dioxins are inevitably produced, which causes environmental pollution problems.wholesale activated carbon pellets
Activated carbon powder injection combined with bag dust collector (ACI+ BF) is an effective and widely used method to control dioxin emission from incinerator flue gas.
In order to provide reference and theoretical basis for the preparation and selection of activated carbon for the adsorption of dioxins, this paper carried out a study on the combined technology of activated carbon injection and double bag dust collector, the characteristics of activated carbon adsorption for dioxins and the influencing factors of activated carbon adsorption for dioxins.The adsorption and desorption isotherms of 13 kinds of commercial activated carbon were determined by low temperature nitrogen adsorption method, and the physical structures of activated carbon were calculated according to BET, T-Plot, BJH and DFT theory, and the iodine value and methylene blue value of 4 kinds of activated carbon were detected.
The physical structure characteristics of activated carbon were analyzed in detail to prepare for the subsequent experiment.
Using small activated carbon fixed bed adsorption gas phase dioxin test bench, a typical activated carbon adsorption dioxin factors affecting the experimental study, discusses the types of dioxin adsorption activated carbon and activated carbon fixed bed adsorption gas phase characteristics of dioxins, and discusses the adsorption temperature and adsorption time of activated carbon adsorption of dioxins.The results showed that the specific surface area and micropore volume of activated carbon had weak correlation with the adsorption efficiency of dioxins.
The mesopore volume of activated carbon is an important factor to determine the adsorption capacity of dioxins. The surface area of the pore size between 2 nm and 20nm plays a key role in the adsorption of dioxins.The higher the adsorption temperature, the lower the adsorption efficiency of activated carbon.The longer the adsorption time, the lower the adsorption efficiency of activated carbon.There is no selective adsorption of gaseous dioxins in activated carbon fixed bed.
