Polygeneration systems, due to their operation flexibility and efficiency, have become in the technological core of distributed generation systems. However, design and control of these systems involve multiple factors ...

Water and energy consumption has increased substantially over the last decades. Water scarcity has led to an increase in the extraction of fresh water from aquifers, dams, and lakes, and it has produced serious overexploitation ...

The economic factor is often the determinant one in the design of a chemical process; however, the current problem related to environmental damage and social problems, demands to include criteria that consider a sustainable ...

Doped and vertically aligned ZnO nanorod arrays with different aspect ratio were synthesized by combining atomic layer deposition (ALD) followed by microwave hydrothermal processing. Firstly, the growing of a ZnO textured ...

In this work is presented the production of several titanium dioxide photocatalysts with higher activity than the TiO2 commercial Degussa P25 in both reaction systems, liquid and gas phase. This photocatalysts were obtained ...

In this thesis study, Water Boiling Tests (WBT) were used, as standard of a cooking task, to evaluate carbon monoxide (CO) and particulate matter (PM2.5) emissions contribution and performance parameters for five improved ...

It is predicted that biobased chemicals could in the near future occupy a market share much greater than today. The biorefinery concept could be particularly advantageous when considering the conversion of waste products ...

Carbon nanotubes, both single and multi-wall, have excellent mechanical properties and are currently the subject of numerous studies to evaluate their friction behavior as a reinforcement in metallic and polymeric matrix ...

This thesis presents the formulation and implementation of a multi-objective optimization model to maximize the annual profit and minimize the environmental impact of regenerative steam power plants with reheat integrated ...

Methodologies for the optimization of the supply chain for the production of biofuels are proposed in this work. In a first case study, proposes a methodology for the optimization of the configuration of a biorefinery, ...
