Abstract

The aims of this work are to produce membranes and to investigate their utilization in the detoxification of the hemicellulosic hydrolisate originated from the acid treatment of sugarcane bagasse. For that, two types of membranes will be produced from three different types of polymers, cellulose acetate obtained from sugarcane bagasse, commercial cellulose acetate and polyamide 66. For the production of the sugarcane bagasse cellulose acetate it will be conducted an exploratory study in order to extract cellulose, raw-material of the acetate, in a manner that the final material possessed high purity degree and the losses of cellulose during the process were minimized. The technique of phase inversion will be utilized to produce the membranes. In the case of cellulose acetate membranes, the variation of the membrane production parameters (time of solvent evaporation, temperature of coagulation bath and thermical treatment) will be performed for the purpose of establishing the best process parameters, whereas it will be utilized previously established conditions found in the literature for the polyamide membrane production. The membranes will be characterized physically and for their properties of pure water flux, vapor water flux, salt rejection, sugar rejection and toxic compound rejection. Finally, the membranes will be applied in the process of hemicellulosic hydrolysate detoxification for testing their capacity of furfural, hydroxymethylfurfural (HMF), acetic acid and phenolic compound removal.
