METHOD AND SYSTEM FOR ENHANCING CARBON CONVERSION AND SELECTIVE SYNTHESIS OF SEMICONDUCTING SINGLE-WALLED CARBON-NANOTUBE FIBERS

Absstract of: WO2026022841A1

The present invention discloses a radial mixing system (100) and method (800) designed to enhance carbon conversion and selectively synthesize semiconducting single-walled carbon nanotube (SWCNT) fibers via floating catalyst chemical vapor deposition (FC-CVD). A mixed solution of a carbon source, catalyst precursor, and promotor in specified atomic ratios, is prepared. This solution is vaporized in a preheater (106) and the resulting vapors are introduced into a reactor (102) maintained at predefined temperatures. A fan (104), rotating at a defined RPM, facilitates mixing in the evaporation and re-nucleation zones. The process yields cylindrical SWCNT aerogels (108) in the re-nucleation zone, which exit the reactor via carrier gas flow. Subsequent condensation in a water bath unit (112) converts the aerogels into SWCNT fibers (114), collected efficiently on a rotating roller (120).
