US 2022/0032264 A1 · SOLID SUPPORT COMPRISING CARBON NANOTUBES, SYSTEMS AND METHODS TO PRODUCE IT AND TO ADSORBE ORGANIC SUBSTANCES ON IT

Abstract

Method for manufacturing an inert solid support with optionally functionalised carbon nanotubes (CNTs), comprising the steps of: i) providing an inert solid support and at least one catalytic metal associated with, or absorbed in, or adsorbed/deposited on, said support, said metal being optionally selected from among the group consisting of iron, cobalt, nickel, molybdenum and combinations thereof; ii) supplying a source of gaseous, liquid or solid carbon to the catalytic metal; iii) through chemical vapor deposition (CVD), depositing at least part of the carbon source at the catalytic metal as CNTs, stably connected to the inert solid support. The present invention further regards an inert solid support and a separation method.

Method for manufacturing inert solid supports with optionally functionalised carbon nanotubes (CNTs), comprising steps of:

i) providing inert solid supports and at least one catalytic metal absorbed in, or adsorbed or deposited on, said supports, said metal being optionally selected from among the group consisting of iron, cobalt, nickel, molybdenum and combinations thereof;
ii) supplying a gaseous, liquid or solid carbon source to the catalytic metal;
iii) through chemical vapor deposition (CVD), depositing at the catalytic metal at least part of the carbon source as CNTs, stably connected to the inert solid supports;
wherein the inert solid supports are in the form of particulate, granule or pellet with an over-nanometric particle size distribution, that is inert solid supports having an average size distribution comprised from 0.1 mm to 5 mm, and wherein the CNTs are in the form of scattered bundles or tangle, grouped at the catalytic metal.
