Abstract

This project aims the development of methods to produce hierarchically structured aluminas for applications in heterogeneous catalysis. Features such as high rates of mass transfer, high surface area and considerable catalytic potential confer to hierarchically structured ceramics a great scientific and technological interest. Aluminas with controlled size distribution and pore volume will be produced from the conjugation of sol-gel process with phase separation aiming its use in the catalytic conversion of ethanol. The products of ethanol conversion will be evaluated from aluminas impregnated with metallic copper to form active sites. The kinetic control of induced phase separation and gelation during the preparation process must enable the obtaintion of ceramic materials with macro-mesopores. The synthesis routes will be optimized by adjusting the parameters of preparation and evaluating the effect of pore structure on the catalytic activity and selectivity for the ethanol conversion into products of economic interest. Various experimental techniques of structural characterization of porous materials and analysis of catalytic activity will be employed aiming to study of correlations between processing parameters of porous ceramic materials with the structural and catalytic properties.
