Atol® is a technology for the most profitable production of polymer grade bio-ethylene by dehydration of 1G and 2G renewable ethanol.

The bio-ethylene produced can be integrated in existing downstream polymerization installations such as polyethylene (PE), polystyrene (PS), polyethyleneteraphthalate (PET), polyvinylchloride (PVC) and acrylonitrile-butadiene-styrene (ABS) without need for modifications.

Atol® relies on Axens Solutions’ high performance catalyst (ATO 201) and on an innovative process providing the following main features:
Robustness to feedstock qualities: Atol® has the flexibility to handle with different quality of ethanol from 1st and/or 2nd generation coming from several sources even highly diluted.
High catalyst activity: significantly less catalyst required as compared to conventional catalyst, resulting in the reduction of reactor volume and catalytic cost.
In-Situ Regenerable catalyst ensuring long catalyst life time and handling with feedstocks quality fluctuation
Optimized reaction section for maximum heat recovery.
Simplified ethylene purification section due to high catalyst selectivity
Robust and reliable process scheme with only fully proven solution.

Based on a high performance catalyst and innovative process, Atol® opens the way to a very attractive production of bio-ethylene from renewable resources with improved Ethylene yield and lower energy consumption (and lower CO2 emissions) with equipment optimization.
