The thermochemical direct liquefaction process involves converting biomass to an oily liquid by contacting the biomass with water at elevated temperatures (250-350°C) with sufficient pressure to maintain the water primarily in the liquid phase (12-20 MPa) for resi­dence times up to 30 minutes (Figure 2.3). It mimics the natural geological processes thought to be involved in the production of fossil […]

Phylogeny, Growth, Yield and Chemical Composition

4.1.1 Phylogeny Miscanthus is a C4 perennial grass of tropical and subtropical origins with a wide area of distribution (Figure 4.1). It belongs to the Poaceae family, a subfamily of Panicoidae, the tribe of Andropogoneae and the subtribe of Saccharineae. Among others, the gen­era Miscanthus, Saccharum and Erianthus belong to this subtribe [8]. The phylogeny of Miscanthus was first described […]

(Bio)Chemical Conversion Route

Biochemical conversion comprises breaking down or “cracking” biomass by using physical, chemical, enzymatic and/or microbial action, to make the polymeric carbohydrates of the biomass (hemicellulose and cellulose) available as (fermentable) sugars, which can then be converted into biofuels and bioproducts using microorganisms (bacteria, yeast, fungi, etc.) and their enzymes or chemically converted using specific catalysts. A general overview of the […]

Summary and Conclusions

Lignocellulosic biomass is seen as an attractive feedstock for future supplies of renewable fuels and biochemicals. Their abundant supply makes them attractive candidates to replace oil-based liquid fuels and chemicals. Substantial investment is occurring in conversion technologies and in determining the most economic, practical and cleanest technology for the production of these lignocellulosic-based chemicals.
