Carbon Nanotubes are one the most important materials of future. Discovered in 1991, they have reached a stage of attracting the interests of many companies world wide for their large scale production. They possess remarkable electrical, mechanical, optical, thermal and chemical properties, which make them a perfect "fit" for many engineering applications. In this paper various methods of production of carbon nanotubes are discussed outlining their capabilities, efficiencies and possible

Chemical vapor disposition (CVD) is proposed as a potential method for economic large scale production of carbon nanotubes due to its relative simplicity of operation, process control, energy efficiency, raw materials used, capability to scale up as large unit operation, high yield and purity. an effort has been ma homa [19] , to develop a process using Cobalt and Molybdenum catalysts and CO gases. In this method, SWNT are grown by CO disproportionation (decomposition into C and CO 2 ) in the presence of CoMo Catalyst (specifically developed for the purpose) at 700˚C -950˚C in flow of pure CO at a total pressure that typically ranges from 1 to
