Since the prohibition of leaded gasoline, MTBE/ETBE has long been used to increase the octane number of the gasoline pool.

The function of the MTBE/ETBE unit is to selectively transform reactive isobutylene from the C4 cut into Methyl-Tertiary-Butyl-Ether/Ethyl-Tertiary-Butyl-Ether (MTBE/ETBE) by etherification with methanol/ethanol.

Axens MTBE/ETBE technologies are based on a specific concept of expanded catalytic-bed reactors and also on a state-of-the-art reactive distillation system called CatacolTM. In addition to overcoming equilibrium limitations, Catacol minimizes catalyst cost because, unlike other catalytic systems, Catacol does not require proprietary internals or internal packaging.

Based on in-depth expertise, Axens provides optimum solutions for every type of application thanks to a very flexible offer, from moderate conversion to ultimate conversion with a very high selectivity which is required for petrochemicals applications and especially for the 1-Butene production.
