METHOD FOR PRODUCING MULTIWALL CARBON NANOTUBE AEROGEL FROM BIOGAS Abstract Disclosed is a method for producing multiwall carbon nanotube (MWCNT) aerogel having density below 0.10 g/cc, from an optimized biogas feedstock containing methane and carbon dioxide only, without requiring any external carrier gas. The f...

SYSTEM AND METHOD FOR MANUFACTURING MULTIWALL CARBON NANOTUBES Abstract Disclosed is a system (100) for manufacturing multiwall carbon nanotubes and a method of conversion of hydrocarbon to multiwall carbon nanotube, with or without using carrier gases. In fixed bed multistage reactor (30) of the present inventio...
