“…Moreover, the aqueous phase reforming (APR) can be used as a replacement for the gasification process [ 150 ]. The APR is a process that converts oxygenated hydrocarbons dissolved in water into H 2 through a catalytic reaction [ 150 ]. The APR results in a gas mainly composed of H 2 , CO, CH 4 , CO 2 and light alkanes.…”

“…Although no studies were found where winery wastewaters or residues were submitted to APR process, Zoppi et al (2022) reported a yield between 91.2 and 789.1 mg of H 2 per g of C for brewery and fruit juice wastewater. Moreover, lignocellulosic biomass can also be used in this process after appropriate pretreatment such as hydrolysis [ 150 ]. According to the authors, hydrogen can be produced through a green low-cost technology, such as an aqueous phase reforming process.…”

The wine industry is one of the most relevant socio-economic activities in Europe. However, this industry represents a growing problem with negative effects on the environment since it produces large quantities of residues that need appropriate valorization or management. From the perspective of biorefinery and circular economy, the winery residues show high potential to be used for the formulation of new products. Due to the substantial quantities of phenolic compounds, flavonoids, and anthocyanins with high antioxidant potential in their matrix, these residues can be exploited by extracting bioactive compounds before using the remaining biomass for energy purposes or for producing fertilizers. Currently, there is an emphasis on the use of new and greener technologies in order to recover bioactive molecules from solid and liquid winery residues. Once the bio compounds are recovered, the remaining residues can be used for the production of energy through bioprocesses (biogas, bioethanol, bio-oil), thermal processes (pyrolysis, gasification combustion), or biofertilizers (compost), according to the biorefinery concept. This review mainly focuses on the discussion of the feasibility of the application of the biorefinery concept for winery residues. The transition from the lab-scale to the industrial-scale of the different technologies is still lacking and urgent in this sector.

“…Aqueous phase reforming (APR), an alternative methodology for the in situ generation of H 2 directly from biomass or derived molecules, has proved to be an efficient approach for the cleavage of C–C and C–O bonds. 117,118 Compared to conventional steam reforming, APR occurs under milder reaction conditions in one pot, breaking the C–C, C–H, and C–O bonds, releasing H 2 from the substrates, which is utilized for the hydrogenolysis of the cleaved molecules. Along these lines, Li et al demonstrated a hydrogen-free strategy for preparing 4-alkylphenols from lignin using the Pt/NiAl 2 O 4 catalyst via APR.…”

“…The aqueous phase reforming (APR) method is regarded as an inexpensive method for producing H2 due to its lower temperature and lack of vaporizing water and fuels [29,30].Glycerol has a wide product distribution due to its complexity compared to low-chain hydrocarbons or alcohols and to the numerous reactions associated with the reforming process (Figure 2). However, this technique creates H2 without vaporizing the feedstock, resulting in significant energy savings [31]. Supercritical water gasification (SCWG)) is a cost-effective method of turning biomass (such as food waste, paper industrial waste, sewage sludge, agricultural waste, and forestry residue) into hydrogen-rich syngas [32].…”

The valuable products produced from glycerol transformation have become a research route that attracted considerable benefits owing to their huge volumes in recent decades (as a result of biodiesel production as a byproduct) as well as a myriad of chemical and biological techniques for transforming glycerol into high-value compounds, such as fuel additives, biofuels, precursors and other useful chemicals, etc. Biodiesel has presented another challenge in the considerable increase in its byproduct (glycerol). This review provides a recent update on the transformation of glycerol with an exclusive focus on the various catalysts’ performance in designing reaction operation conditions. The different products observed and cataloged in this review involved hydrogen, acetol, acrolein, ethylene glycol, and propylene glycol (1,3-propanediol and 1,2-propanediol) from reforming and dehydration and hydrogenolysis reactions of glycerol conversions. The future prospects and critical challenges are finally presented.
