Microwave heating can produce good effects in the preparation and modification of activated carbon (S2. Microwave modification, many backwater hole is opened, the distributed capacitance change obviously, promoting the improvement of the adsorption. The microwave power and irradiation time are key determinants of modified activated carbon adsorption performance. On the mechanism of microwave carbonization and activation, it is generally believed thatgranular activated charcoal buy  Plant waste is mostly made of plant fiber raw materials, in the plant body under the action of capillary, modified solution absorbed by material whole fully, between fiber is filled with the subtle space, make the dry material volume expansion after soaking wet, and reaction. Because of the water in the raw material, modified solution constitute a polar molecule, with a strong absorption of microwave dielectric properties,Therefore, polar molecules collide and rub violently with microwave frequency, generating a large amount of heat, which makes water and modified solution volatilize rapidly, and generate steam pressure, which explodes out from the inside of the raw material to the outside. This sharp action makes the fiber space of the raw material expand and produce sharp drying.In this way, the raw material has a more obvious pore structure and a larger internal specific surface area than before microwave irradiation. Compared with the traditional heating method, the mechanism of microwave in the preparation process of activated carbon is completely different.It shows its unique advantages: high efficiency, energy saving, uniformity, selectivity, low pollution, high thermal efficiency, low energy consumption, simple process and equipment and small footprint, conducive to automation, low carbon loss, and recovery of useful substances.www.coalactivatedcarbon.com   Many theoretical problems in this new field, especially the microwave heating mechanism, need to be further studied, and the mathematical model of the heating process needs to be established  [View Answers]

Due to the high requirement of activated carbon for water pretreatment, and the high price of activated carbon, so in wastewater treatment, activated carbon is mainly used to remove trace pollutants in wastewater, in order to achieve the purpose of deep purification. carbon pellets  1. Activated carbon treatment of wastewater containing chromium. Chromium is a kind of metal raw material used in electroplating. The hexavalent chromium in wastewater exists in different forms with different pH values. Activated carbon has a very developed microporous structure and high specific surface area, has a strong physical adsorption capacity, can effectively adsorb Cr (V) in wastewater. There are a large number of oxygen-containing groups on the surface of activated carbon, such as hydroxyl (-OH), carboxyl (-COOH), etc., which all have the function of electrostatic adsorption and produce chemical adsorption on Cr (VI). It can be completely used to treat Cr (VI) in electroplating wastewater, and the adsorbed wastewater can meet the national discharge standard. The results showed that when the mass concentration of Cr (VI) in the solution was 50mg/L, pH=3 and adsorption time was 1.5h, the adsorption performance and Cr (VI) removal rate of activated carbon reached the best effect. Therefore, the process of treating wastewater containing chromium by activated carbon is the result of the comprehensive action of physical adsorption, chemical adsorption and chemical reduction of Cr (VI) in solution by activated carbon. Activated carbon treatment of wastewater containing chromium has stable adsorption performance, high treatment efficiency, low operating cost, and certain social and economic benefits.https://www.chinactivecarbon.com   2. Treatment of cyanide-containing wastewater with sexual carbon. In industrial production, cyanide or by-product cyanide is used in the wet extraction of gold and silver, the production of chemical fiber, coking, synthesis of ammonia, electroplating, gas I production and other industries, so a certain amount of cyanide-containing wastewater must be discharged in the production process. Activated carbon has been used to purify wastewater for a long time and there are more and more reports on its application in the treatment of cyanide-containing wastewater. However, due to the small adsorption capacity of CN_ and HCN on activated carbon, which is generally 3mgCN/ GAC --8mgCN/ GAC depending on the variety, it is not cost-effective in the treatment cost. 3. Activated carbon treatment of wastewater containing mercury. Activated carbon has the ability to adsorb mercury and mercury-containing compounds, but its adsorption capacity is limited, and it is only suitable for treating wastewater with low mercury content. If the concentration of mercury is high, it can be treated by chemical precipitation method first. After treatment, the mercury content is about 1mg/L, and it can reach 2-3mg /L when high, and then further treatment with activated carbon. Activated carbon, is black powder or block, granular, honeycomb amorphous carbon, but also a regular arrangement of crystalline carbon.In addition to carbon elements, activated carbon also contains two kinds of admixtures: one is the chemical combination of elements, mainly oxygen and hydrogen, these elements are due to incomplete carbonization and residual in the carbon, or in the activation process, foreign non-carbon elements and activated carbon surface chemical combination;Another kind of admixture is ash, which is the inorganic part of activated carbon, and ash in active carbon is easy to cause secondary pollution.Because of its strong adsorption, activated carbon is widely used in production,In the life.Activated carbon material is processed by the amorphous carbon, has a large specific surface area, the gas, solution of inorganic or organic matter and colloidal particles have good adsorption capacity.Activated Carbon materials mainly include Activated Carbon (AC) and Activated Carbon Fibers (ACF), etc.Activated carbon material as a kind of excellent adsorbent, mainly because of its unique adsorption surface structure and surface chemical properties.Activated carbon material has stable chemical properties and high mechanical strength.  [View Answers]

Adsorption capacity refers to the amount of adsorbents adsorbed on the adsorbent per unit mass under certain conditions. It is usually expressed in terms of K adsorbents /kg of adsorbent or mass percentage, which is a sign of the adsorption capacity of the adsorbent. carbon pellets  In industry, the amount of adsorption is called the activity of the adsorbent. The activity of the adsorbent can be expressed in two ways :(1) the static activity of the adsorbentUnder certain conditions, the equilibrium adsorption capacity of the adsorbent is its static activity.For a certain adsorption system, the static activity depends only on the adsorption temperature and the concentration or partial pressure of the adsorbed substance.

Activated carbon treatment of phenol-containing wastewater. Phenol-containing wastewater is widely sourced from petrochemical plants, resin plants, coking plants and oil refining and chemical plants. The experimental results show that the activated carbon has a good adsorption performance for phenol, but the increase of temperature is not conducive to adsorption, so that the adsorption capacity is reduced.www.coalactivatedcarbon.com   But the time to reach adsorption equilibrium is shortened by increasing the temperature. The optimum values of the amount of activated carbon and the adsorption time were found, and the removal rate changed little under acidic and neutral conditions. Under the condition of strong alkalinity, the removal rate of phenol decreased sharply, the stronger the alkalinity, the worse the adsorption effect. granular activated charcoal buy  [View Answers]
