Descrição: This work is part of a project to develop ceramic filters to treat flue gases from cement plants, biomass boilers and waste incinerators. Ceramic filters used for these purposes must present high porosity, homogeneous porous distribution (interconnected) to result in bodies with high mechanical strength, permeability and collection efficiency for fine particles. A method recently developed has been used for the filters processing. In this new processing route, the porous samples were prepared through the incorporation of aqueous foams into alumina-based suspensions. Compared to other techniques, this process seems to be an attractive and cost effective solution for fabricating complex shaped bodies, without toxic admixtures. The procedure to establish the required features of the filtering membrane for a desired flow condition is described, as well as the experimental work to produce and select the ceramic membranes with such requirements.
