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. Furthermore, biological

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 on the in‐depth knowledge of
their... 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 systems are considered
for produc... 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 lignocellulosic feedstock, is being developed. This

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 gasifi cation was investigated. The

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 10–15 % of fossil oil‐based
bulk che... 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 with gasoline, diesel and
natural g... 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, and product recovery has been

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: water scrubbing, organic
solvent... 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 modest heating value). The second scenario employs
fast pyrolys... hiện toàn bộ
