“…Concerning the optimization of the catalysts, the crucial parameters are pore diffusion and acid strength. It is well agreed in the literature that medium acid sites and rather large pores are favorable for increased long-term stability 85), 86) . Hence, we focused on silica-supported silicotungstic acid (STA) and optimized the catalytic long-term stability by (i) choosing SBA-15 as a support with a tailor-made pore-size of 8 nm and (ii) introducing zirconia nanoparticles in SBA-15 in order to moderate the acidstrength of the subsequently supported STA by modulated electronic interactions 87) .…”

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.

“…Silicotungstic acid supported on silica with mesopores of 10 nm showed the highest catalytic activity with an acrolein selectivity of >85 mol% under ambient pressure at 275 °C [4]. Ning reported that activated carbon (AC)-supported silicotungstic acid can be used as glycerol dehydration catalyst.…”

Abstract. Acrolein is currently produced using propylene from crude oil while its price and scarcity are increasing. A renewable material such as glycerol is an attractive alternative for acrolein production. It can be obtained from crude palm oil (CPO) and is a byproduct of biodiesel production. Besides being able to compete economically, glycerol is an environmentally friendly material. The purpose of this study is to synthesize acrolein from glycerol using FePO 4 catalyst in liquid phase dehydration. The catalyst was prepared by three different methods: hydrothermal (catalyst A), deposition at Fe/P = 1.15 (catalyst B), and deposition at Fe/P = 1.20 (catalyst C). The experimental reaction temperature was varied at 220, 240 and 260 °C under constant atmospheric pressure. The results showed that catalyst C provided the best yield (91%), followed by catalyst A (90%) and catalyst B (82%). The increasing reaction temperature showed a tendency to increase the yield of acrolein, while the presence of oxygen reduced the yield of acrolein and allowed the reaction to produce more side products such as glycerol propanal, acetaldehyde, and propionate. Catalyst reuse without any regeneration resulted in a yield profile of acrolein that continued to decline.

“…19,20 Among the heterogeneous solid acids, heteropoly acids (HPAs) due to their stronger acidity, have been extensively studied as acid catalysts for many reactions, such as the synthesis of trioxanes, 21 alkylation of benzene with olefins, 22 and gas-phase selective oxidation of various organic substrates. Heteropoly acids have many advantages over other acid catalysts, including being non-corrosive, environmentally benign and possessing superacidic properties.…”

The aim of the research described was to study Rb 2 HPW 12 O 40 as a green and heterogeneous catalyst for the Mannich reaction. One-pot multi-component condensation of an aldehyde, an amine and a ketone at ambient temperature affords the corresponding β-amino ketones using novel nano-sized Rb 2 HPW 12 O 40 . Simple purification, short reaction time and high yield are some of the advantages of this reaction. Also, the catalyst can be readily isolated. The nano catalyst Rb 2 HPW 12 O 40 has been characterized by Fourier transform infrared spectroscopy, X-ray powder diffraction and scanning electron microscopy.
