FIELD: manufacture and treatment of carbon nanostructures; thermo-chemical activation of carbon nanotube surfaces for increase of their sorption ability.
SUBSTANCE: proposed device consists of steel body with working chamber where cylindrical graphite heater is mounted; heater is made in form of two coaxial cylinders whose upper butts are interconnected; outer cylinder is connected in its lower part with current leads; it is surrounded by graphite shields and heat-insulating layer. Device is also provided with vertical rod moving inside heater; secured on this rod is two-chamber graphite container consisting of sleeve loaded with zinc sulfide, partition with carbon nanotubes and sealing cover. Zinc sulfide vapor from sleeve flows through walls of container partition and carbon nanotubes to colder members of device. As a result, carbon nanotube surface gets activated with zinc sulfide vapor by means of chemical reaction.
EFFECT: enhanced efficiency.
