Title:
METHOD FOR PRODUCING CARBON NANOFIBERS
Document Type and Number:
WIPO Patent Application WO/2017/022553
Kind Code:
A1
Abstract:
Provided is a method for producing carbon nanofibers having excellent conductivity, crystallinity and dispersibility. A method for producing carbon nanofibers, which uses an activated species mainly composed of cobalt as a catalyst, while using carbon monoxide as a carbon source. The catalyst is obtained by having a carrier, which is composed of an oxide having a specific surface area of 0.01-5 m2/g and containing magnesium, support 3-90% by mass of the activated species. By controlling the reaction temperature, the carbon monoxide partial pressure and the gas flow rate of the carbon monoxide, CNF having more excellent conductivity, crystallinity and dispersibility can be produced, thereby obtaining carbon nanofibers having excellent conductivity, crystallinity and dispersibility.
