Our Services
Sorption Global Technologies will develop a highly efficient and non-toxic product, Exfoliated Graphite (EG). EG will be developed in powder form. Our product is free from all kinds of pollution and toxicity for marine life. Our unique selling proposition is that our products have very high sorption rates compared to more enormous sponges available in the market.
Our Powder Sorbents will have multiple selling points, including better control of wettability. Our products carry reduced interfacial tension with a higher surface-to-volume ratio. They will have great results as our testing phase proved exceptionally efficient in cleaning high viscosity oils. Their significant impact will protect marine life by delivering better performance in thin layered large area oil spills.
Powder Sorbents promptly absorb oil once subjected to oil/water mixtures. They have super water repellency & oil absorbency, making them highly effective. The surface energy of our products will turn to be higher than oils (15 30 mN /m) and lower than water (78 mN /m).

Physical absorption is the most economical and efficient choice due to:
- Low cost
- Simple operation
- Environmentally-friendly
- High selectivity
- Easy scale-up
WHY POWDER SORBENTS?
Advantages
- Better control of wettability
- Reduced interfacial tension
- Higher surface-to-volume ratio
- Exceptionally efficient in cleaning high viscosity oils
- Better performance in thin-layered large-area oil spills
Challenge
- Limited oil absorption capacity
Our Solution
- Increasing the oil absorption capacity through a specific chemical modification process.
HOW IT WORKS
- Exfoliated Graphite promptly absorbs oil once subjected to oil/water mixtures.
- Super water-repellency & oil-absorbency make it highly selective
- Surface energy of product was tuned to be higher than oils (15-30 mN/m) and lower than water (78 mN/m).
How to collect the beads:
- To make the collection of saturated beads easier, we magnetized the product.
- Iron oxide nanoparticles were incorporated in the reaction.
How to recover the saturated beads & powders:
- The oily aerogel can be squeezed to remove the absorbed oil.
- The oily EG powder is exposed to ethanol or hexane to be recovered.
