High performance green barriers based on nanocellulose
- 2014
Abstract With the increasing environmental concerns such as sustainability and
end-of-life disposal challenges, materials derived from renewable resources such
as nanocellulose have been strongly advocated as potential replacements for
packaging materials. Nanocellulose can be extracted from various plant resources
through mechanical and chemical ways. Nanocellulose with its nanoscale
dimensions, ...
Valorisation of food waste to biofuel: current trends and technological challenges
Tập 2 - Trang 1-4 - 2014
Demand for biofuels is rapidly growing worldwide as petroleum based fuels are
finite reserves. In this context, biodiesel and bioethanol are popular biofuels
that are commercially available in various countries. Biofuels can be prepared
from edible biomass. However, this is already generating food versus fuel debate
among the members of civil societies. Therefore, there are needs to synthesize
bio...
Combination of modern plant breeding and enzyme technology to obtain highly enriched erucic acid from Crambe oil
Tập 4 - Trang 1-5 - 2016
Fatty acids from vegetable oils are useful building blocks for industrial
materials. The purpose of this work was to prepare erucic acid with high purity
from a vegetable oil. High purity erucic acid is used for the production of
erucamide with applications in plastics manufacturing. A newly developed
transgenic Crambe line produces seed oil with 68 % erucic acid compared to 53 %
in the wild type ...
Continuous flow transformations of glycerol to valuable products: an overview
Tập 2 - Trang 1-10 - 2014
Glycerol conversion to valuable products has been a research avenue that
attracted a significant interest in recent years due to its large available
volumes (as by-product of biodiesel production) and the different possibilities
for chemical and biological conversion into high added value chemicals profiting
from the unique presence of three hydroxyl groups in its structure. The
utilization of con...
Thermochemical processes for biofuels production from biomass
Tập 1 - Trang 1-10 - 2013
The contribution of biomass to the world’s energy supply is presently estimated
to be around 10% to 14%. The conversion of biomass to biofuels can be achieved
primarily via biochemical and thermochemical processes. Recently, the use of
thermochemical processes as pyrolysis and gasification has received great
attention. The biomass composition and form of process conduction can affect
greatly the e...
Two-step process for preparation of oligosaccharide propionates and acrylates using lipase and Cyclodextrin Glycosyl Transferase (CGTase)
Tập 2 - Trang 1-8 - 2014
Oligosaccharide esters are attractive candidates for applications as
surfactants, hydrogels and other materials, but direct enzymatic acylation is
difficult with carbohydrates longer than disaccharides. A combination of one
lipase-catalyzed step and one transglycosylation step catalyzed by a
cyclodextrin glycosyl transferase (CGTase) was used to synthesize
oligosaccharide esters. The conversion of...
Biorefinery lignosulfonates as a dispersant for coal water slurry
Tập 4 - Trang 1-8 - 2016
Valorization of lignin from biofuel production is the key to developing
biorefinery technologies for sustainable and economic utilization of
lignocellulosic biomass. Here we present isolating lignosulfonate from the spent
liquors of Sulfite Pretreatment to Overcome the Recalcitrance of Lignocelluloses
(SPORL)-pretreated lodgepole pine and Douglas-fir forest residue as a dispersant
for coal water s...
Microwave assisted chemical pretreatment of Miscanthus under different temperature regimes
Tập 3 - Trang 1-13 - 2015
Miscanthus is a major bioenergy crop in Europe and a potential feedstock for
second generation biofuels. The most efficient and realistic method to produce
fermentable sugars from lignocellulosic biomass is by enzymatic hydrolysis,
assisted by thermo-chemical pretreatment. Recently, microwave technology has
drawn growing attention, because of its unique effects and performance on
biomass. In this ...
