Abstract:

In 2012, Michelin, IFPEN and Axens decided to develop a bio-based on-purpose technology to produce butadiene from ethanol, named BioButterfly. The BioButterfly process, based on the Ostromislensky process, mainly consists in three stages: a catalytic stage with ethanol conversion to butadiene, a second stage consisting in products separation and a last stage consisting in butadiene purification. All those stages have been demonstrated at laboratory and pilot scales with original experimental set-ups for catalyst, solvent and technology developments. The present paper focuses on the scale-up strategy followed by the partners with tests on a cold flow model and the pre-industrial demonstration unit built in the Michelin factory at Bassens (FR).
