Special Issue Information

Dear Colleagues,

During the last several decades, biorefinery has been taking a share in the fuels market. With the requirements on carbon footprint reduction for petrochemical industries, biorefinery is expected to significantly increase in the near future. Glycerol is the main by-product of biodiesel, and therefore it will be generated in tremendous amounts, with the real possibility of market saturation. Glycerol transformation in other products has been extensively investigated since the 1990s. A great number of compounds can be produced from glycerol through reforming, thermochemical reaction, hydrogenolysis, oxidation, etc. Some of these technologies require a large energy input, which might prevent/hinder their industrial implementation. As an alternative, emergent routes are focus on reducing the energy input and obtaining new products, for instance; photoconversion uses direct light as energy input to produce and accelerate chemicals reactions; electro-conversion which can get the low energy input from sun through solar panels; developing new catalysts active at lower temperatures. These types of routes have been widely reported on in the literature, however, the current typical yields achieved through these processes are lower than those achieved with conventional thermochemical processes, requiring research in this field. This Special Issue focuses on significant advances in heterogeneous catalysts for glycerol conversion focus on reducing the amount of energy input or new catalytic routes for glycerol transformation.    

The aim of this Special Issue is to cover the research trends in catalysts for the conversion of glycerol with low energy input. Full papers, short communications, and reviews in this field are welcome. Mini-reviews with an overview on the state of the art with the future perspectives and trends will also be considered.

The chemo-selective hydrogenolysis of secondary hydroxyls is an important reaction for the production of biomass-derived α,ω-diols. This is the case for 1,3-propanediol production from glycerol. Supported Pt-WOx materials are effective catalysts for this transformation, and their activity is often related to the tungsten surface density and Brönsted acidity, although there are discrepancies in this regard. In this work, a series of Pt-WOx/γ-Al2O3 catalysts were prepared by modifying the pH of the solutions used in the active metal impregnation step. The activity–structure relationships, together with the results from the addition of in situ titrants, i.e., 2,6-di-tert-butyl-pyridine or pyridine, helped in elucidating the nature of the bifunctional active sites for the selective production of 1,3-propanediol.
