Presentation Transcript

  1. Conceptual Design of Continuous Processes for Carbon Nanotubes Adedeji E. Agboola and Ralph W. Pike Louisiana State University Helen H. Lou, Jack R. Hopper and Carl L. Yaws Lamar University Thomas A. Hertwig Mosaic Corporation Paper No. 289n, American Institute of Chemical Engineers Annual Meeting, Cincinnati, Ohio Oct. 30- Nov. 4, 2005

  2. Brief History of Carbon Nanotubes • Discovered by Iijima and co-workers in 1991 • CNT structures consist of carbon filaments with a small diameter (nm) and a large length (µm) - A molecular model of a single wall carbon nanotube

  3. Properties - High Aspect Ratio Structures - High Mechanical Strength: Tensile Strength (60 GPa) and Young Modulus (1 – 5 TPa) - High Electrical Conductivity (typically 10-6 ohm m) - High Thermal Conductivity (1750 – 5800 W/mK) - High Current Density (107 – 109 A/cm2) - Chemical Stability: (not attacked by strong acids/alkali)

  4. Nanotube Composites - Ideal substitutes to carbon fibers as reinforcements in high strength, low weight and high performance composites - Application in aerospace construction

  5. Carbon Nanotube Laboratory Synthesis Techniques

  6. Summary of Conceptual Designs of CNT Processes

  7. Process Units

  8. CNT Process using Fluidized Bed Reactor

  9. CNT Process using Plug Flow Reactor
