Resumen de Mineral-based gas adsorbents: : the halloysite example

Joachim Schomburg, Tom Conway, Gary Nelson

• In developing the potential of halloysite nanotubes (HNT) for gas component adsorption, several laboratory and pilot plant studies were performed with different types of halloysite materials.

  The HNT-granulates can be used as single adsorbent material or in combination with low Temperature Plasma Technology for treatment of gas streams or polluted air (WO 2009/125004; WO 2011/128073).

  I-Minerals' Helmer-Bovil project is located in western Idaho, and the company's 2013 prefeasibility study highlighted the potential of the property as having an after tax NPV of $150m, 28% IRR, 3 year payback and $67m initial CAPEX.
