The capture of CO2 from flue gases derived from fossil-fueled power plants and the absorption of CO2/H2S for natural gas sweetening purposes are two relevant industrial problems closely related to very important environmental, ...

This study presents the investigation of entropy generation in compressible turbulent flow of air through a diffuser. Constant temperature boundary condition is applied at the wall. Two-dimensional solution of velocity and ...

A series of Cu-doped TiO2 catalysts were prepared by a sol-gel method and the effect of various synthesis parameters, including solvent type; solvent/catalyst amount; amount of water; catalyst type/amount; and acid type, ...

© 2018 Elsevier B.V. The application of ceramic microfiltration membranes to the tertiary treatment of produced water from an Arabian Gulf oilfield has been studied using a dedicated pilot plant. Studies were based on a ...

In the present chapter, we describe different types of investigation carried out by research groups based at CQE/IST/UTL and ITQB/UNL and their ramifications in terms of surface science. Most of the work is focused on the ...

The properties of solutions formed by dialkylcarbonate + 1-alkanol solutions are studied using classic molecular dynamics simulations. The effects of solution composition, temperature, and dialkylcarbonate type have been ...

An overview on the preparation and properties of resorcinol-formaldehyde (RF) organic and carbon gels reveals the fascinating and remarkably flexible properties of RF carbon and organic gels and how these properties are ...

We report herein a combined experimental–computational study on tris-(2-hydroxylethyl)methylammonium methylsulfate in water solutions, as a representative ionic liquid of the aqueous-solution behavior of hydroxylammonium-based ...

Reporting sludge accumulation in septic tanks as a constant rate is no longer accepted, and there is a need for a model that predicts sludge accumulation in septic tanks taking into consideration the continuous consumption ...
