“…Lignocellulosic biomass commonly consists of cellulose (35-50%), hemicellulose (20-35%) and lignin (10-25%) as major components, with proteins, oils, and ash completing the remaining fraction. 9,10 As summarized in Fig. 1, after the corresponding chemical pretreatment of biomass, the cellulosic and hemicellulosic fractions give rise to the so-called C5 and C6 platforms since they are polymers from whose hydrolysis hexoses like glucose or fructose and pentoses like xylose, most abundantly, can be obtained.…”

“…Torrefied biomass is also more brittle, which should help facilitate the mechanical fluidization and heat transfer inside the MFR. [29][30][31][32] In the future, various biomass are considered, with or without torrefaction as pretreatment, and centered on forestry residues such as perturbation wood or unloved wood.…”

Forest biomass is an attractive alternative resource to fossil ones, renewable and without environmental impacts as long as forest residues are considered. Collecting and transforming forestry residues into value-added products is a challenge as they are usually scattered over a large area. To reduce the economic and environmental cost of forestry residues transformation, in-situ energy densification is a powerful solution. To achieve efficient energy densification of forestry residues and transformation for industrial use, a new pyrolysis unit designed by the University of Western Ontario is used to produce low water content pyrolysis oil and high-quality biochar. Bio-oil with 8 %wt water content is produced. Energy density of the bio-oil is compared to other densification methods, showing the interest of pyrolysis to increase the energy density of biomass. High quality and free of sand biochar is also produced. Various properties of the bio-oil and biochar are explored to determine its potential for various industrial applications in the scope of a major biorefinery project in La Tuque, Québec.

“…With fossil fuels depleting, the demand for alternative, more sustainable routes to produce fuels and chemicals is steadily growing. A reorientation of research towards renewable resources is putting biorefineries into the spotlight for the conversion and valorization of biomass‐derived streams [1–3] . Lignocellulose, the most abundant biomass on the planet, [4] can be transformed into a large variety of platform chemicals, starting from lignin, cellulose, and hemicelluloses (e. g., producing xylose and other pentoses).…”

The conversion of lignocellulose into its building blocks and their further transformation into valuable platform chemicals (e. g., furfural) are key technologies to move towards the use of renewable resources. This paper explored the disentanglement of lignocellulose into hemicellulose‐derived sugars, cellulose, and lignin in a biphasic solvent system (water/2‐methyltetrahydrofuran) using phosphoric acid as recyclable catalyst. Integrated with the biomass fractionation, in a second step hemicellulose‐derived sugars (mainly xylose) were converted to furfural, which was in situ extracted into 2‐methyltetrahydrofuran with high selectivity (70 %) and yield (56 wt %). To further increase the economic feasibility of the process, a downstream and recycling strategy enabled recovery of phosphoric acid without loss of process efficiency over four consecutive cycles. This outlines a more efficient and sustainable use of phosphoric acid as catalyst, as its inherent costs can be significantly lowered.
