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...
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...
The use of combination of zeolites to pursue integrated refined pyrolysis oil from kraft lignin
- 2014
A mixture of Y and M type zeolites were applied to pyrolyze kraft softwood (SW)
lignin with the objective of studying the combination effect of different types
of zeolite on pyrolysis. The chemical structures of the subsequent pyrolysis
oils were examined. Nuclear Magnetic Resonance (NMR) spectroscopy including 13C,
31P of phosphitylated bio-oils, Heteronuclear Single-Quantum Correlation
(HSQC)-NM...
Nano Cu-catalyzed efficient and selective reduction of nitroarenes under combined microwave and ultrasound irradiation
Tập 2 - Trang 1-6 - 2014
In situ preparation of copper nanoparticles from a copper acetate precursor and
its application as an efficient catalyst for the selective reduction of aromatic
nitro compounds with hydrazine hydrate under combined microwave and ultrasound
irradiation were described in detail. The results reveal the synergetic effect
of microwave and ultrasound on the synthesis of copper nanoparticles, and
formati...
Scale up and efficient bioethanol production involving recombinant cellulase (Glycoside hydrolase family 5) from Clostridium thermocellum
Tập 1 - Trang 1-11 - 2013
Lignocellulose degrading fungal enzymes have been in use at industrial level for
more than three decades. However, the main drawback is the high cost of the
commercially available Trichoderma reesei cellulolytic enzymes. The hydrolytic
performance of a novel Clostridium thermocellum cellulolytic recombinant
cellulase expressed in Escherichia coli cells was compared with the naturally
isolated cell...
Recent advances on biobutanol production
Tập 2 - Trang 1-9 - 2014
Recent studies have shown that butanol is a potential gasoline replacement that
can also be blended in significant quantities with conventional diesel fuel.
However, biotechnological production of butanol has some challenges such as low
butanol titer, high cost feedstocks and product inhibition. The present work
reviewed the technical and economic feasibility of the main technologies
available to ...
