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 ...

Cobalt-based catalysts supported on γ-alumina and magnesium aluminate modified with lanthanum and cerium have been applied to various conditions of reforming of ethanol. The initial challenge was to control the rate ...

Previous works have shown that the presence of electrostatic forces in particles significantly affect the performance of a filter, both increasing collection efficiency and reducing pressure drop. Recently, in the Environmental ...

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. ...

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 minimization of the emissions of nitrogen oxides (NOx) in the atmosphere has been one of the great goals in the area of environmental protection. Among the possible processes to treat the NOx, the selective catalytic ...

The drying process of particulate biological materials in fixed bed is influenced by several factors associated with the particles and the bed packing. The main objective of this research was to evaluate the drying of ...

One of the major problems faced by humanity nowadays is the issue of preserving the environment. In recent years, progress has been accelerated, having a direct influence on the environmental impacts caused by several kinds ...

Fructose (1,3,4,5,6-pentahydroxyhex-2-one) is an important sugar in global market because its unique characteristics when compared to another sugars. It becomes the fructose economically attractive besides the fact that ...
