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. 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. 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. Dynamic activity of adsorbents Under certain operating conditions, the gas mixture by adsorption bed, adsorption by adsorption, adsorption after a period of time, when starting from the adsorbent in the laminar flow of the gas adsorbed mass (or its concentration reaches a specified value), think bed fire, adsorption properties of adsorbent adsorption quantity at this time is called dynamic activity of adsorbent. The activity is not only related to the characteristics of adsorbents and adsorbents, but also related to temperature, concentration and operating conditions.

Specific surface area test unified the multi-point BET method at home and abroad, specific surface area measurement standards are developed at home and abroad is based on BET test method, please see our national standard (GB/T 19587-2004) - gas adsorption BET principle of solid material specific surface area measurement methods. Specific surface area testing is actually the more time-consuming jobs, as the adsorption capacity of sample is different, some sample testing may need to spend the whole dayTime, if the test process is not fully automated, the tester can not leave at any time, and should be highly focused, observe the dashboard, control the knob, a little careless will lead to the failure of the test process, which will waste a lot of valuable time of the tester. activated carbon from china 
Wastewater treatment technology of powdered activated carbon02020-10-27 01:05:13
Powdered Activated Carbon Treatment (PACT) is a wastewater technology in which powdered activated carbon is added to an anaerobic or aerobic treatment system.carbon activated manufacturer  The carbon in the biological treatment process adsorbs recalcitrant compounds that are not readily biodegradable, thereby reducing the chemical oxygen demand of the wastewater and removing toxins.The carbon also acts as a "buffer" against the effects of toxic organics in the wastewater. In such a system, biological treatment and carbon adsorption are combined into a single, synergistic treatment step.The result is a system which offers significant cost reduction compared to activated sludge and granular carbon treatment options. The addition of the powdered activated carbon stabilizes biological systems against upsets and shock loading, controls color and odor, and may reduce disposal costs while removing soluble organics. In an aerobic treatment system, influent first enters an aeration tank where the powdered carbon is added, making up a portion of mixed liquor suspended solids. pellets activated carbon Once the aeration is completed, the treated wastewater and the carbon-biomass slurry are allowed to settle.In cases where complete solids separation is needed, such as for reuse, an MBR may be used in place of the clarifer. Following treatment, a portion of the carbon and biomass slurry is wasted to solids handling. Due to the presence of the powdered activated carbon, the sludge settles, thickens, and dewaters better compared to conventional activated sludge processes. These solids can be wasted and disposed of as a slurry, dewatered to a compact, stable cake, or pumped as a slurry to a wet air oxidation unit for further processing to regenerate the carbon and destroy the biological solids.

Fir chip as the raw materials, H - POs as activator, using single factor analysis and orthogonal experimental design method, this paper discusses the influence granular activated carbon pore structure and the iodine adsorption value, methylene blue and strength of various preparation factors, determine the optimum process conditions of preparation of granular activated carbon phosphoric acid, phosphoric acid concentration is 70%, dipping 180%, kneading temperature is 170 ℃, for 60 min kneading time, activation temperature is 350 ℃, the activation time of 210 min.http://www.streetcarsrater.com/forum/topic/254307  The iodine adsorption value, methylene blue adsorption value, imagitarium activated carbon pellets 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. Therefore, granular activated carbon with good adsorption performance and high strength can be prepared by this method.
