The inhibitory effect of ethanol on yeast and the temperature rise during the fermentation are the major drawbacks of the conventional ethanol production process. The use of extractive alcoholic fermentation with CO2 ...

Natural zeolites are the most important inorganic cationic exchangers exhibiting high ion exchange capacity, selectivity and environment compatibility. Heavy metals are well known for toxicity and their disposal is a ...

Heterogeneous photocatalysis is a technology that can be used for the treatment of wastewater and one of the interesting aspects of this technique is the possibility of using visible light (solar) to activate the photocatalyst. ...

Mitigation of atmospheric pollutants emission and recovery of high-added value products are the main goals of studies on the optimization of devices that collect nanoparticles, which harmfulness is reported in the scientific ...

Constant exposure to high concentrations of particulate matter present in the air has increased the number of cases of cardiorespiratory disease and death. Since then, has been a need for the development and improvement ...

This work aims to contribute to the development of the ethanol production process from xylooligomers (XO) extracted from sugarcane bagasse hemicellulose through the hydrolysis of XO to xylose, xylose isomerization catalyzed ...

Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...

The biofuels production is a promising alternative for decreasing fossil fuels dependency globally. Great efforts have been made in the search for energy optimization of the biofuel production process, in order to improve ...

The selective catalytic reduction of NOx with ammonia is the best technology available today to carry out the abatement of nitrogen oxide emissions in industrial gas effluents. Currently, vanadia-titania catalysts promoted ...

In this work, the electrodeposition of toxic metals, copper and zinc in this case, onreticulated vitreous carbon (RVC) electrode was studied. The effect of EDTA presence on thecopper electrodeposition process was also ...
