Abstract

The applications of inorganic nanomaterials have been under the spotlight worldwide given the fact that they present desirable characteristics in many fields such as catalysis, medicine, environment, food, beauty and others. In Chemical Engineering, the nanomaterials, or the nanoparticles, have essential application, for instance, in the design of catalysts with great superficial area and diameters less than 20 nm. High purity nanoparticles with narrow size distribution can be efficiently and economically manufactured in reactors of flame spray pyrolysis (FSP). The FSP process is able to produce mixtures of powders of metallic oxides with sizes between 1 and 200 nm from low cost precursors. The majority of previous studies regarding the FSP process, especially the Double-Flamed FSP for the production of multicomponent nanomaterials, have focused on the synthesis of the nanoparticles and on the qualitative discussion of the process parameters on the final product. However, the broad understanding of the FSP process is fundamental for scale-up studies. The main goal of this project is to develop a tridimensional mathematical model capable of representing the process of production of nanoparticles in FSP reactors through CFD technics combined with multivariate population balances in order to determine the right process conditions for the controlled manufacture of multicomponent nanoparticles.
