In domestic has been eliminated. 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.
F - Sorb 2400 specific surface tester is really able to BET method detection instruments (both direct comparison method), the more important F - Sorb 2400 specific surface tester is by far the only specific surface area of the fully automated intelligent testing equipment, the test results with the international high consistency, the stability is very good also, at the same time reduce the human error, improve accuracy test results.
The adsorption capacity of activated carbon on each gas (unit: mL /cm3):H2, O2, N2, CI2, CO2
4.5, 35, 11, 494, 97 The main factors affecting the adsorption of activated carbon ? the nature of activated carbon adsorbentactivated charcoal manufacturers
The surface area of the activated carbon should include the inner surface area and the outer surface area. In fact, the adsorption properties mainly come to the inner surface area of the white Li large, so it can not be mistaken for: the activated carbon grinding and grinding will significantly improve the surface area to improve the adsorption force.gold recovery activated carbon
Many adsorbations are recursive physical adsorption, that is, the adsorbed matter is a fluid, which is adsorbed by activated carbon at a certain temperature and pressure. At high temperature and low pressure, the adsorbed matter desorbs out, and the inner surface of activated carbon returns to its original state.
Separation, purification and separation of liquid purification and other fields.
The industrial application of activated carbon by appearance distinguish forming granular activated carbon, are there not finalize the granular activated carbon, powdered activated carbon, activated carbon fiber, etc., main application fields including wastewater treatment, activated carbon depth clean drinking water, medicine and food decolorizing refining, precious metal extraction, gas separation and purification, solvent recovery, and military and civil protection.
Taking coal as raw material to the production of coal based activated carbon is a kind of has a developed interspaces structure of carbonaceous adsorption material, has good chemical stability and mechanical strength, coal based activated carbon products can be widely used in decoloring purification, solvent recovery, gas separation, gas purification, and various kinds of water treatment and other fields, some through special processing, the special T also can be used as a high-performance activated carbon desulfurization agent, catalyst and catalyst carrier, mountain in the acid and alkali resistant, heat resistant, granular activated carbon on adsorption saturation after failure, can be a party to regenerate.The application of coal-based activated carbon is divided into liquid phase and gas phase according to the characteristics of the material. The liquid phase is mainly used in decolorization, recovery of precious metals and water treatment.
