4. What We do

11. Intellectual Property Further application - specific patents will be filed covering novel recipes, devices and where possible processes employed. Patent Summary International Patent Application No. PCT/GB2006/002509 entitled “ Hollow fibres” Number of hollow fibre recipes for robust and flexible nano-porous fibres, including a method and apparatus for processing of highly viscous dopes. UK Patent Application No. 07049349 Hollow fibre recipes, and adsorption units based on the use of conductive fibres that can be easily “regenerated”. UK Patent Application No. P402739 Advanced Compressed Air Treatment Design

14. Technology - benefits Benefit Comment High Efficiency High surface area/volume ratio (>3000 m 2 /m 3 ) compared to state of the art monoliths (800-1000 m 2 /m 3 ). Low vacuum/thermal swing requirements for regeneration. High added value products The manufacturing process depends on the patented technology and process know-how. Sales will be targeted at high added value applications where there are technical advantages over existing technology. Lightweight, compact and low energy use Products can be configured and operated in many ways, horizontally, vertically, or coiled. They are particularly suitable for limited space, weight and power applications. Robust Use of multiple layers enables high reliability products to be fabricated that can withstand handling and vibration during operation and maintenance.
