Abstract:
... Switchgrass (Panicum virgatum) is a perennial grass highly valued as an energy crop resource for the production of bioethanol due to its high carbohydrate content, fast growth, and ability to grow in lands that cannot support crop or food production. In the present study, this biomass was submitted to steam explosion pretreatment in a semi-continuous pre-pilot reactor with the aim of obtaining a p ...

Abstract:
... Hydrothermal Liquefaction (HTL) is a versatile thermochemical pathway that converts wet or moist biomass into a bio-oil with promising properties as a future replacement of fossil oil. Lignocellulosic biomasses are of particular interest as they are representative of almost all terrestrial plant material. The fibrous nature of lignocellulosic biomass may however induce clogging and damage in conti ...

Abstract:
... Perennial crops, as energy feedstocks, offer ecological advantages over fossil fuels by contributing to the reduction of greenhouse gases and fossil energy savings. Yet, the intensity of agricultural production may increase the pressure on soil, water resources and on biological and landscape diversity. Moreover, land use competition with food crops is demanding a spatial segregation of energy pro ...
