Up-Scaling of the Biobutterfly Process
Short Introductive summary
The BioButterfly process is based on the Ostromislensky process, involving the catalytic conversion of ethanol into butadiene through a 2-stage catalytic transformation. The first step is the dehydrogenation of ethanol into acetaldehyde, which is a partial and highly endothermic catalytic reaction subjects to deactivation. To design and optimize the associated multitubular fixed bed type industrial reactor, a complete reactor model combining kinetic, heat and mass transfers and deactivation models was developed, based on a wide set of experimental tests perfomed at lab, bench and pilot plant scales. This work will make it possible to optimize catalyst life cycle, so as to maximize productivity and minimize the cost of butadiene production which is key to make this technology a success.
