“…In spite of numerous designs for catalytic packings, there is no catalytic packing which can satisfy an increased reaction efficiency as well as a high separation capacity. In industrial processes, most catalytic packings consist of wire gauze baskets filled with catalyst granulate, like e.g.…”

An enantioselective biocatalytic reaction was carried out for the first time in a fully integrated batch reactive distillation setup. The investigated reaction was the lipase catalyzed kinetic resolution of a racemic mixture of (R/S)-2-pentanol with ethyl butyrate. The reaction is strongly limited by the reaction equilibrium so that the reactive distillation helped to shift the equilibrium toward the product side. The enantioselectivity of the applied lipase was high with ee values >99% for 2-pentanol at conversions of 69 ± 3%. As established in our previous work, the biocatalyst was again immobilized within a hydrophobic silica coating for structured packings. The production of the biocatalytic coating was further developed as a spray-coating method to allow reproducible coatings which also can be applied on larger surfaces. The influence of the coating on separation efficiency and pressure drop was studied as well as the stability of the coating under the required process conditions. Overall, this work demonstrates the first kinetic resolution in a reactive distillation setup with structured packings and presents the catalytic coating as an alternative structure for (bio)catalytic columns internals.

“…Reactive distillation most often is performed in packed columns, but combining reaction and distillation in tray columns is also quite widely practiced (see, e.g., Keller). Estimating the tray efficiency for reactive distillation processes is not at all straightforward; there is no model that can represent all possible reactions.…”

One of the characteristics in the production of biobased platform molecules is the highly diluted reaction mixtures obtained from the chemical/biological treatment of biomass.…”

Biomass valorization is a booming field. Especially, the valorization of platform molecules by catalytic processes has driven a large interest in the recent years, and many groups are actively working on the transformation of biosourced substrates to a variety of upgraded chemicals. In this context, in the present paper we put in perspectives the scientific works of our research team. We first classified catalytic transformations of industrial interest according to the number of carbons of the starting material, from C1 to C6. They involve, among others, acid catalysts (e.g., for glycerol dehydration), redox catalysts (e.g., for 5-HMF conversion to diformylfuran), acid and redox catalysts (e.g., for direct acetalization of alcohols), or complex multifunctional catalysts, especially for the Guerbet reaction. Further, we also developed what we called 'toolboxes,' which are general concepts or technologies with a broader field of applications. For example, we adapted the two zones fluidized bed reactor (TZFBR) concept to the single reactor continuous regeneration of coking catalysts. Further, we designed a completely new high throughput platform enabling synthetizing, characterizing and testing the performances of many catalysts for considerably accelerating the catalysts discovery/optimization loop.
