Hierarchical TiO2 nanofibres as photocatalyst for CO2 reduction: Influence of morphology and phase composition on catalytic activity
|
emi+d |
In this research work, the gas phase CO2 photocatalytic reduction using water as electron donor has been performed using hierarchical assemblies of mesoporous TiO2 1-D nanofibres synthesised by a combination of electrospinning and sol–gel methods. In order to compare the effect of the crystallisation step on oxygen vacancies and conductivity, two different annealing conditions have been underta... |

Enzymatic hydrolysis from carbohydrates of barley straw pretreated by ionic liquids
|
emi+d |
Lignocellulosic biomass offers many potential advantages in comparison with the traditionally used sugars or starchy biomass since it’s vastly available and it does not compete with food and feed production. The abundance and high carbohydrates content of barley straw make it a good candidate for bioethanol production in Europe. Since biomass must be pretreated before enzymatic hydrolysis to im... |

OPTIMIZATION OF INTEGRATED ALKALINE-EXTRUSION PRETREATMENT OF BARLEY STRAW FOR SUGAR PRODUCTION BY ENZYMATIC HYDROLYSIS
|
emi+d |
In this work, an integrated one-step alkaline-extrusion process was tested as pretreatment for sugar production from barley straw (BS) biomass. The influence of extrusion 10 temperature (T) and the ratio NaOH/BS dry matter (w/w) into the extruder on pretreatment effectiveness was investigated in a twin-screw extruder at bench scale . A 23 factorial response surface design of experiments was use... |

Improving the fermentation performance of Saccharomyces cerevisiae by laccase during ethanol production from steamexploded wheat straw at high substrate loadings
|
emi+d |
Operating the saccharification and fermentation processes at high substrate loadings is a key factor for making ethanol production from lignocellulosic biomass economically profitable. However, increasing the substrate loading presents some disadvantages, among them larger generation of inhibitors, which negatively affect fermentation performance. In this study, laccase enzymatic treatment was ... |

Comparing cell viability and ethanol fermentation of the thermotolerant yeast Kluyveromyces marxianus and Saccharomyces cerevisiae on steam-exploded biomass treated wi...
|
emi+d |
In this study, the thermotolerant yeast Kluyveromyces marxianus CECT 10875 was compared to Saccharomyces cerevisae Ethanol Red for lignocellulosic ethanol production. For it, whole slurry from steam-exploded wheat straw was used as raw material, and two process configurations, simultaneous saccharification and fermentation (SSF) and presaccharification and simultaneous saccharification and ferm... |
