Six sequences of reactive distillation followed by a separation unit (conventional, thermally coupled and thermally coupled with minimum use of reboilers, each one in direct and indirect form) for the biodiesel production ...

The present work studies some possibilities that have for the recycling of tereftalato of polyethylene (PET) and polyethylene (PE), looking for its technical, economic and environmental feasibility. Currently the effect ...

In this work, the foundations were proposed to carry out the numerical simulation of the combustion process in chemical looping cycles, using computational fluid dynamics. This process consists of two interconnected reactors: ...

In this thesis the feasibility of producing biodiesel using mesoporous Al-SBA-15 acid catalysts was analyzed. A model feedstock oil with high content of free fatty acids was employed in this study. The effect of the ...

deterioration have evoked the development of alternative fuels, for example biodiesel, syngas, bioalcohols and many others. This work is focused on production of syngas and biodiesel. The syngas is a blend of hydrogen and ...

Nowadays, aerobic treatment of residual waters is accomplished by “activated sludge” systems, this sludge’s help in the process of degradation of the organic matter present in urban or industrial effluents. Activated sludge ...

About one-third of global CO2 emissions come from the use of fossil fuels in power generation. There are different technologies available and under development that concentrate CO2 streams from combustion sources, i.e., ...

In this project the development of an approximate analytic solution for the process of diffusion and reaction with deactivation by coke formation in an isothermal catalyst particle is presented. The approximate analytical ...

The reactions that are carried out in the Fischer-Tropsch synthesis, represent an important route, in the production of liquid hydrocarbons, through the use of Iron or Cobalt catalysts mainly, supported in gamma alumina ...

The objetive of this work was to produce etanol in a fermentation process using a biocatalyst consisting of Saccharomyces cerevisiae yeast flocs induced adhesion of functionalized carbon nanotubes. Carbon nanotubes were ...
