Subject: Dingxinda activated carbon black abrasive paint
Content: In painting, printing, shoe making, plastic, rubber, bonding and other industrial processes, there are a large number of organic waste gas emissions.These waste gas, often contain benzene, toluene, xylene, ethyl acetate, methanol and other organic matter, itself toxic, long-term damage can lead to human death.The emission of this kind of waste gas, countries have clear provisions, strict control of its emission concentrationThe treatment of organic waste gas has been studied for a long time, and some effective control technologies have been developed.The widely used and studied control techniques include adsorption method, thermal destruction method, condensation method, absorption method, etc. activated carbon pellets wholesale emissions.It is estimated that more than 30 million tons of organic matter are released into the atmosphere worldwide every year, posing a serious threat to human health and plant and animal growth.Organic pollutants are mostly produced in industrial processes. In painting, printing, shoe making, plastic, rubber, bonding and other industrial processes, there are a large number of organic waste gas emissions.These waste gas, often contain benzene, toluene, xylene, ethyl acetate, methanol and other organic matter, itself toxic, long-term damage can lead to human death.The emission of this kind of waste gas, countries have clear provisions, strict control of its emission concentrationThe treatment of organic waste gas has been studied for a long time, and some effective control technologies have been developed.The widely used and studied control techniques include adsorption method, thermal destruction method, condensation method, absorption method, etc. Among them, the adsorption method is widely used.Compared with other methods, the adsorption method has the advantages of high removal efficiency, thorough purification, low energy consumption, mature technology, recovery and solution, easy popularization and practical, and has good environmental and economic benefits.Activated carbon is the most commonly used adsorbent because of its huge specific surface area, large adsorption capacity, easy regeneration, abundant sources and low price.Although the application of charcoal as an adsorbent, human beings have had a long time, but the study of adsorption theory, but only in the end of the last century began to make progress. In 1916, Langmuir studied the adsorption of monolayer molecules and proposed the Langmuir adsorption isotherm equation.Freundlich and Zsigmondy proposed the capillary condensation theory for gas adsorption and obtained the semi-empirical Freundlich adsorption isotherm equation.Temkin also suggested a semi-empirical isothermal equation. china active carbon/ Based on Gibbs equation, Toth used dimensionless function V to derive another adsorption isotherm equation for heterogeneous surfaces.Fowler and Guggenhein derived a formula of the same form from the concept of statistical mechanics.Goldmann and Polanyi proposed the adsorption space theory, which believed that the continuous decrease in the molecular density of multiple layers on the surface of the adsorbent was caused by the weakening of the adsorption molecular force
