“…At that time, the estimated global market was approximately € 293 million per year . In 2016, this value had reached € 625 million and it has been forecasted that by 2022 the global xylitol market will be above € 900 million with an annual production of 267 000 metric tons . The current bulk price varies between 4 and 5 €/kg.…”

Recent Advances in the Catalytic Production of Platform Chemicals from Holocellulosic Biomass

This Review discusses novel catalytic pathways of lignocellulosic biomass to value‐added chemicals including biomass‐derived sugar alcohols, organic acids, furans and biohydrocarbons. These production approaches are undertaken by biological, chemical and thermochemical transformations or a combination of them. Nevertheless, the majority of research in this area is focused on the design of heterogeneous catalysts to convert value‐added products from holocellulosic biomass. Biorefineries represent the peak of biomass processes in order to produce valuable chemicals and liquid fuels avoiding the utilization of corroding and toxic elements. The aim of the present Review is to offer the readers a broad overview of recent holocellulosic‐based chemical and fuels production technologies via heterogeneous catalysis. There is also an overview of the economic aspects to efficiently produce these platform chemicals at industrial scale. To summarize this Review, an outlook and conclusions of the reported processes to date is provided.

“…Compared with rutile, the better dispersion of Ru over anatase does not allow to reach comparable activity nor selectivity to xylitol. As recently reviewed by Delgado Arcano et al., nickel and ruthenium catalysts then remains the most widely studied materials for the xylose to xylitol reaction, while titania is the most suitable support . Replacement of noble metals in catalytic formulations is however preferable due to limited resources, fluctuating costs, and consumption by high‐technology markets.…”

“…Food applications indeed implies the absence of any trace of nickel in the final product, nickel being recognized as a carcinogen compound. Most of recent studies were devoted to the study of supported noble metals, such as Ru, Rh and Pd, in monometallic or bimetallic catalytic systems, with the possible adding of dopants as Sn [8][9][10][11][12][13][14][15] Ru appeared as the most efficient. Hernandez-Mejia et al [16] reported that xylose can be selectively converted to xylitol in the presence of rutile phase TiO 2 supported Ru (1 wt.…”

Selective Hydrogenation of Xylose to Xylitol over Co/SiO₂ Catalysts

et al. 2020

Xylose can be selectively converted to xylitol in water, with an optimized yield of 98 %, in the presence of a simple silica supported monometallic cobalt – Co/SiO2 – catalyst. This catalyst displays initial outstanding catalytic properties in a proper solvent, the best results being obtained in pure water. Recyclability studies show a moderate deactivation of the catalyst, while selectivity to xylitol remains almost unchanged after 4 cycles, confirming that this catalyst formulation is very promising for the xylitol production process.

“…Among them are Scheffersomyces stipitis yeasts 13 and Pachysolen tannophilus, identified as having high potential for pentose alcoholic fermentation. 14 As with 2G ethanol, there is a growing interest in obtaining xylitol, a natural polyalcohol, due to its applicability in the food and pharmaceutical industrial segment, 15 mainly due to its anti-cariogenic properties and the possibility of ingestion by diabetics, because its metabolism, unlike that of sucrose, does not require insulin activity. It is also used in the medical field because it is a nontoxic compound and its use is safe for humans.…”

Beer production generates brewer's spent grain as a byproduct. This biomass contains lignin, cellulose, and hemicellulose, and can be used for the production of second‐generation (2G) ethanol and xylitol. For this to be economically viable, fermentable fractions must be used, allowing the conversion of cellulose and hemicellulose to ethanol. This study evaluated the fermentation of hemicellulose liquor from brewer's spent grain (HLBS) in aerobic and oxygen‐ limited conditions using Scheffersomyces stipitis and Pachysolen tannophilus. Results were compared with data obtained in a complex medium (YPX) and a minimal medium (MMX). In aerobic conditions, for S. stipitis in the HLBS medium, μ max = 0.12 h−1, Y ethanol/xylose = 0.14 and selectivity for ethanol over xylitol (S ethanol/xylitol) 3.4 gethanol g−1 xylitol were obtained. Under oxygen‐limited conditions, Y ethanol/xylose = 0.22 and S ethanol/xylitol = 1.17 gethanol g−1 xylitol were obtained. For P. tannophilus, under aerobic conditions, the HLBS medium gave μ max = 0.08 h−1, and Y ethanol/xylose = 0.005, with selectivity for ethanol over xylitol (S ethanol/xylitol) of 0.12 gethanol g−1 xylitol. In oxygen‐limited conditions, Y ethanol/xylose = 0.09 and S ethanol/xylitol = 0.20 gethanol g−1 xylitol were obtained. This is because the metabolism of these aerobic yeasts directs the carbon flow to cell growth, while with oxygen limitation it is directed to metabolite production. The HLBS medium was promising for production in the context of a biorefinery. When comparing the two yeasts, S. stipitis presented better ethanol production and P. tannophilus better xylitol production under the conditions that were studied. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
