The technology of modification with carbon nanotubes of one of the most widespread industrial sorbents - zeolite of the CaA and NaX brands is proposed. The modification technology consisted in the preparation of a multicomponent mixture of nano- and microdispersed bulk materials containing zeolite, carbon nanotubes (CNTs) and, as a binder, bentonite clay. Then the resulting mixture was molded, dried and heat treated.The optimal content of the binder (20 and 30 %) and carbon nanotubes (2.5 and 2 %) for the modified versions of the CaA + CNT and NaX + CNT zeolites, respectively, has been experimentally established. The sorption capacity of modified zeolites for toluene vapor has been determined.
