Process for preparing catalyst composition for the synthesis of carbon nanotube with high yields using the spray pyrolysis method

摘要

The invention carbon nanotubes; relates to a process for preparing (Carbon Nanotube CNT) composite catalyst composition. More specifically, the present invention is one of the main catalytic metal selected from Fe or Co; Al; Fe, Co, Ni, Cu, Sn, Mo, Cr, Mn, V, W, Ti, Si, Zr, at least one metal selected from crude Y catalyst; And a process for producing a multi-component metal catalyst composition comprising an inert support Mg, by dissolving the precursor of the metal catalyst composition in water to prepare a catalyst mixed solution, the reactor of the high temperature to the catalyst mixture as a gas atomizing method sikimyeo by spraying a high-temperature pyrolysis to form a catalyst powder, and a method for producing a catalyst composition for synthesizing carbon nanotubes using the spray pyrolysis method consisting of a step of obtaining the catalyst powder. The carbon nanotube composite catalyst composition prepared by the method has a very low apparent density of 0.01~0.50g / mL can be prepared in a high yield of carbon nanotubes Yield 1000~1800%.
