  • Technology Overview

    Water capture and dehumidification of climate-controlled areas are typically performed in energy intensive processes with single use materials, or those that are difficult to regenerate. While these materials are effective in capturing water, the inability to recycle these materials efficiently, limits their applicability.

    Aluminium fumarate is a non-hazardous water capture material that can be regenerated under very favourable conditions. It is from a family of materials called Metal-Organic Frameworks (MOFs) which exhibit ultra-high micro-porosity and surface area. This high surface area allows for a large amount of water or other guest molecules to be attracted to the surface of the framework. Aluminium fumarate is also well suited for water capture due to its remarkable moisture and thermal stability that further prolongs the lifespan of the material in use.

    Technology Features & Specifications

    • High porosity (approx. 0.66 cm3/g)
    • High specific surface area (approx. 1000 m2/g)
    • Thermally stable up to 400°C
    • Pore size suitable for water vapour
    • Moisture stable
    • Readily produced in appropriate form factors (e.g. pellets of different sizes and shapes)
    • Good particle size control

    Potential Applications

    • Water vapour capture (dehumidification, water harvesting)
      - Atmosphere control (moisture control)
      - Potable / Grey water treatment 
      - Water reclamation in water limited environments 
    • Methane capture
      - Capture of fugitive methane emissions from landfill 
    • CO2 capture
      - Post-combustion capture of CO2 from power plants
    • Adsorption heat pump
      - Use in refrigeration cycles
      - Efficient air-conditioning

    Customer Benefits

    • Cheaper to operate with respect to material lifespan and energy cost
    • Reusability
    • Less energy intensive in regenerating MOFs when compared to zeolites
    • Safer than LiCl which can leach and damage equipment
    • Stability in humid environment
    • Wide operating range for humidity
    • Scalable production process with competitive material costs
