In this present work, the fluidynamic and drying process of paste in a spouted bed was analyzed. The experiments were conducted using polyethylene particles of 4.38 mm of diameter and 930.5 ± 0.3 kg/m3 of specific mass ...

Sugarcane, grown in more than a hundred countries, is one of the major crops of the world. Brazil is the world’s largest producer. Sugarcane industries are constantly seeking to reduce the industrial process losses, to ...

Wastewater management has gained increasingly space on the world stage, with significant advances in both the environmental and financial spheres. Phenolic compounds are present in wastewater of various processes, such as ...

Electrodeposition of a PbO2 film was performed onto reticulated vitreous carbon (RVC) substrates with porosities of 45, 60, and 80 ppi, at 65 ºC in a flow reactor, starting with a solution containing Pb(NO3)2, surfactant, ...

Taylor-Vortex reactor (TVB) is fast becoming the next bioreactor to culture animal cells due to milder shear and homogeneous flow structures through-out the bioreactor in comparison to the traditional stirred vessels. ...

Brazil is the second largest producer of soybean, with the projection of becoming the largest producer in 2019/2020. All Brazilian soybean oil is produced by the extraction process with hexane, an oil derivative. One way ...

Heterogeneous catalysts are potentially responsible for reducing the cost of producing biodiesel, due to its reusability or use in continuous process. As-synthesized hybrid silicas, containing siloxy sites, can be used as ...

Vinasse derived from beverage industry represents a serious environmental risk if not properly treated, mainly attributable to the presence of organic macromolecules with complex structure and composition, the recalcitrant ...

Alumina-supported platinum catalysts were synthesized via conventional impregnation varying the metal contents (0.3 to 2% Pt; 6 to 20% Ce, m / m) and the Pt precursors (H2PtCl6 and [Pt(NH3)4] (NO3)2), were evaluated for ...

Due to the high capacity of oxygen transfer and versatility, pneumatic reactors have been constantly used in bioprocesses. However, aiming to expand the use of these bioreactors in the industry, as well as increase the ...
