“…Moreover, S. psammophila is regarded as a promising biomass feedstock for biofuels and bioenergy because of its ease of vegetative propagation, minimal fertiliser requirement and substantial biomass. The stems of S. psammophila require flat stubble once every 3–5 years to allow growth to flourish and its branch residues contain high cellulose, hemicellulose and lignin contents of 55.45%, 18.98% and 25.98%, respectively89. The cellulose content of S. psammophila is higher than those reported in the study of Serapligia et al 10,.…”

Salix psammophila, a sandy shrub known as desert willow, is regarded as a potential biomass feedstock and plays an important role in maintaining local ecosystems. However, a lack of genomic data and efficient molecular markers limit the study of its population evolution and genetic breeding. In this study, chromosome counts, flow cytometry and SSR analyses indicated that S. psammophila is tetraploid. A total of 6,346 EST-SSRs were detected based on 71,458 de novo assembled unigenes from transcriptome data. Twenty-seven EST-SSR markers were developed to evaluate the genetic diversity and population structure of S. psammophila from eight natural populations in Northern China. High levels of genetic diversity (mean 10.63 alleles per locus; mean HE 0.689) were dectected in S. psammophila. The weak population structure and little genetic differentiation (pairwise FST = 0.006–0.016) were found among Population 1-Population 7 (Pop1-Pop7; Inner Mongolia and Shaanxi), but Pop8 (Ningxia) was clearly separated from Pop1-Pop7 and moderate differentiation (pairwise FST = 0.045–0.055) was detected between them, which may be influenced by local habitat conditions. Molecular variance analyses indicated that most of the genetic variation (94.27%) existed within populations. These results provide valuable genetic informations for natural resource conservation and breeding programme optimisation of S. psammophila.

“…Other solvents are chloroform [111,112], acetone [92,113], tetrahydrofuran [83] or alkanes and aromatic compounds [101,112]. Even though rarely considered in the literature, the choice of extraction solvents can directly affect the amount and quality of the bio oil [112,114,115]. The polarity of the solvent will impact the type of molecules recovered in the bio oil.…”

International audienceThe upcoming depletion of fossil fuels calls for the development of alternative energies produced from renewable resources. Particularly, energy valorisation of agriculture and food processing wastes is one of the most promising tools for renewable energy production. The amount of food wastes is rapidly increasing due to urbanisation, industrialisation and population growth worldwide. They consequently represent a widely available resource, and their use as a raw material allows reducing the environmental cost associated with their disposal. These resources usually have high moisture content, making dry valorisation processes unattractive because of a costly drying step prior to conversion. Hydrothermal processes are conversely particularly well suited for the valorisation of wet organic wastes in an economical way, since they use water as the reaction medium. More specifically, liquid fuels can be produced using hydrothermal liquefaction (HTL). The process converts wet biomass into a crude-like oil with higher heating values up to 40 MJ/kg using subcritical water (T=250-370 degrees C, P=10-30 MPa). Though this is an active research area, the mechanisms of hydrothermal liquefaction still remain unclear today. Some processes have already been developed at the pilot scale for valorising food processing wastes. However, the development of HTL processes at industrial scales is facing technological and economic challenges. This paper discusses the two main issues to address for development of the process at large scales. On the one hand, hydrothermal conversion of food processing residues and model compounds is necessary to better understand the fundamentals of hydrothermal liquefaction. As well, technological and process integration issues have to be addressed to ensure economic viability of commercial HTL processes

“…El biocrudo contenido en la fracción líquida se extrajo con diclorometano. La mezcla diclorometano biocrudo se separó posteriormente con evaporación al vacío a 35°C para recuperar diclorometano y obtener biocrudo soluble en agua (Oasmaa et al, 2003;Garcia-Perez et al, 2007;Yang et al, 2014;Zou et al, 2009). Los biocrudos resultantes se mezclaron y el total fue cuantificado y reportado como rendimiento de biocrudo.…”

El objetivo del trabajo fue llevar a cabo la evaluación del proceso de licuefacción con biomasa de Buchón de Agua. Para esto se desarrolló un diseño experimental factorial con un modelo cúbico, determinando el efecto de las variables temperatura, tiempo y relación líquido/sólido (L/S) sobre la variable respuesta Rendimiento Energético (RE). Los mejores resultados se obtuvieron a 300°C, 60 min y L/S=10 (exp. 15) con RE de 6,34 MJ/kg biomasa, a 300°C, 30 min y L/S=10 (exp. 5) con RE de 6,31 MJ/kg biomasa y a 270°C, 60 min y L/S=20 (exp. 9) con 6,29 MJ/kg biomasa, seleccionándose las condiciones del exp. 5 como las más adecuadas dada la menor relación L/S y el menor tiempo de reacción. La ventaja de adicionar catalizador se hizo evidente al comparar los resultados del RE del experimento 26 con catalizador (5,9 MJ/kg biomasa) y del experimento sin catalizador (3,3 MJ/kg biomasa) bajo las mismas condiciones. Se pudo determinar además que los biocrudos se componían principalmente de compuestos aromáticos, ácidos grasos, hidrocarburos alifáticos, cetonas, aldehídos y alcoholes, y ácidos carboxílicos a condiciones más drásticas.
