Synthesis Of Carbon Nanotubes From Natural Gas Using Horizontally Continuous Rotary Reactor System

The present research focuses on the synthesis of carbon nanotubes (CNT) from natural gas (NG) using continuous rotary reactor system. The catalyst of Co- Mo/MgO was used during the synthesis process. Three operating parameters were studied namely the reaction temperature, ratio of natural gas to nit...
