  • Continuous process for producing carbon nanotubes
    Patent number: 9206050
    Abstract: The present invention relates to a continuous process for producing carbon nanotubes (herein after also referred to as “CNTS”) of single, double and/or multi-wall type, with any possible desired diameter and with high purity. The preferred embodiment provides means for continuous supply of a catalyst during the process for producing the carbon nanotubes, according to which one can achieve the advantageous continuity of the process.

  • Hydrodesulphurization Nanocatalyst, Its Use and a Process for Its Production
    Publication number: 20100167915
    Abstract: A nano-supported hydrodesulphurization (HDS) catalyst is prepared for hydrodesulphurization of hydrocarbonaceous feed stock. The catalyst can be prepared through different methods and also used under milder conditions than those required for conventionally used HDS catalysts, but can also function under other hydrodesulphurization operating conditions.
