This is the application of activated carbon in solvent recovery. Ctc% refers to the adsorption rate of carbon tetrachloride, which is a very important index in solvent recovery. The higher the index, the higher the solvent recovery rate and the longer the use time. There are more than 80% CTC commonly used in China, and of course there are many CTC 60% and 70%. In the process of solvent recovery, activated carbon has gone through two processes: adsorption and desorption.

There is such a formula in this process; Working capacity of toluene = adhesion+activity. With the increase of service time, the adhesion is gradually increasing, and this working ability is a constant, so it seems that the activity is gradually decreasing, which means that the amount of analysis is decreasing.

Simply put, activated carbon adsorbs things by developed pores, but in the process of use, the pores will gradually be blocked by adsorbed things, just like smoke stains, which are difficult to remove. Pores are blocked, activity naturally decreases, and adsorption capacity is poor. On the other hand, there is friction between activated carbon during use, which will affect the strength. After a long time, the carbon will be damaged, and the pore size will be destroyed, which will affect the activity of activated carbon. In addition, if the quality of charcoal you buy there is not very good, it will also affect the service life, especially the recycled charcoal. Without more factories, the time index will be greatly reduced and the saturated scrap of charcoal will be accelerated.
