AbstractNew transportation fuels are badly needed to reduce our heavy dependence on imported oil and to reduce the release of greenhouse gases that cause global climate change; cellulosic biomass is the only inexpensive resource that can be used for sustainable production of the large volumes of liquid fuels that our transportation sector has historically favored. ...... hiện toàn bộ

AbstractThe growing demand for transportation fuels, along with concerns about the harmful effects of greenhouse gas emissions from the burning of fossil fuels, has assured a viable future for the development of alternative fuels from renewable resources, such as lignocellulosic biomass. The efficient utilization of these biomass resources is critically dependant o...... hiện toàn bộ

AbstractDeveloping uniformly formatted, densified feedstock from lignocellulosic biomass is of interest to achieve consistent physical properties such as size and shape, bulk and unit density, and durability, which significantly influence storage, transportation and handling characteristics, and, by extension, feedstock cost and quality. A variety of densification ...... hiện toàn bộ
AbstractGovernments across the world are stimulating the valorization of local biomass to secure the energy supply, reduce the emissions of fossil CO2 and support the rural economy. A first generation of fuels and chemicals is being produced from high‐value sugars and oils. Meanwhile, a second generation, based on cheaper and more abundant lign...... hiện toàn bộ
AbstractThis article reviews the work relating to the supercritical water gasifi cation of biomass with a focus on hydrogen production. The high hydrogen yield predicted by thermodynamic calculations and the special properties of near‐ and supercritical water support the biomass degradation; these were the main reasons why the process of = supercritical water gasif...... hiện toàn bộ

AbstractGiven the current robust forces driving sustainable production, and available biomass conversion technologies, biomass‐based routes are expected to make a significant impact on the production of bulk chemicals within 10 years, and a huge impact within 20–30 years. In the Port of Rotterdam there is a clear short‐term (0–10 year) substitution potential of 10–...... hiện toàn bộ

AbstractThis paper deals with a biorefinery classification approach developed within International Energy Agency (IEA) Bioenergy Task 42. Since production of transportation biofuels is seen as the driving force for future biorefinery developments, a selection of the most interesting transportation biofuels until 2020 is based on their characteristics to be mixed wi...... hiện toàn bộ
AbstractThis article reviews bioconversion of plant materials such as wheat straw (WS), corn stover (CS), barley straw (BS), and switchgrass (SG) to butanol and process technology that converts these materials into this superior biofuel. Successful fermentation of low‒value WS makes butanol fermentation economically attractive. Simultaneous hydrolysis, fermentation...... hiện toàn bộ

AbstractThe utilization of biogas produced from organic materials such as agricultural wastes or manure is increasing. However, the raw biogas contains a large share of carbon dioxide which must be removed before utilization in many applications, for example, using the gas as vehicle fuel. The process – biogas upgrading – can be performed with several technologies:...... hiện toàn bộ

AbstractWe estimate the profitability of producing biochar from crop residue (corn stover) for two scenarios. The first employs slow pyrolysis to generate biochar and pyrolysis gas and has the advantage of high yields of char (as much as 40 wt‐%) but the disadvantage of producing a relatively low‐value energy product (pyrolysis gas of mod...... hiện toàn bộ
