Prospects for the Use of Modified Forest Chemical Resins in Obtaining Impregnated Carbon Sorbents

The results of research of the process of obtaining impregnated carbon sorbents on the basis of fine fraction of sorbent of trade mark STK-A and modified forest chemical resin as a binder are presented. The conditions for obtaining impregnated active carbon with high sorption characteristics were determined. The influence of preliminary hydrothermodynamic activation of water-coal suspension being the basis of impregnated sorbent was investigated. It was established that the optimal total content of forest chemical resin in the initial mixture is 30 %, and guaiacol (16 % of binder weight) and creosol (2 % of binder weight) are effective as modifying components that enhance both strength and sorption characteristics of the developed impregnated sorbent. It is proved that the obtained impregnated sorbent is comparable in sorption characteristics with the reference coal granular sorbent of AG-3 trademark.
