PP-52ZEOLITE COATINGS ON SUGAR CANE BAGASSE: A WAY TOACHIEVE ENHANCED SELECTIVITY IN ACID CATALYSIS?Marcelo M. Pereira 1 , Margareth Rose L. Santos 1 , Luciana T.

Rio Branco, 65, CEP 20090-004, RJ, Brazil3 Laboratoire des Matériaux Surfaces et Procédés pour la Catalyse,UMR 7515 du CNRS, University of Strasbourg, 25 rue Becquerel 67087Strasbourg Cedex 2, FranceFrench fries-like ZSM-5 zeolite crystals with a size ranging between 50 and100 nm were grown on sugar cane bagasse surface. Aligned zeolite crystals wereallowed to grow using a combination of supramolecular templating and conventionalself-assembly of template cations and silica species. A relationship has beenestablished between the chemical composition of the vegetal and the morphologyand aggregation degree of zeolite crystals.Zeolite nanocrystals, grown on the sugar cane substrate, allow enhanceddiffusional properties in comparison with purely microporous zeolite materials. Theircatalytic behavior in n-hexane cracking reaction led to a higher selectivity toward lightolefins. Higher selectivities to propylene and ethylene were reached with structuredmesoporous ZSM-5 zeolite. This higher selectivity toward light olefins (alkene/alkaneratio about 20% higher than conventional ZSM-5 zeolite. This result suggests thatimproved diffusion properties within the hierarchical porosity are induced within thesenano French-fries like zeolitecrystals.The double novelty consists inthe synthesis of hierarchical zeolitemicrospheres (diameter about 1μm)formed by the self-aggregation ofmany French-fries like nanocrystals(see Figure 1). In addition, arenewable vegetal source can beused as a supramolecular template inreplacement of expensive polymers.Figure 1 - Self-organized nano-French friesshaped ZSM-5 zeolite crystals.142
PP-53USE OF PATENT APPLICATIONS AS TECNOLOGICAL INDICATORSON THE ETHANOL PRODUCTION FROM LIGNOCELLULOSICBIOMASS IN BRAZILLuiz André F.S. Schlittler 1 , Edelvio de Barros Gomes 2 ,Adelaide Maria S.

E – I. 2000 – SIQUIMRio de Janeiro – RJ – Brazil. Zip: 21.941-909The trends of the industry, nowadays, go towards cleaner technologies to reduceenvironmental pollution. Biotechnology offers environmental, social and economicadvantages that can be considered important factors to develop sustainable actions,especially in rural communities. The lignocellulosic biomass is the richest source ofcarbohydrates in the world and, in the past, due to lack of sustainable technologies. ithas not been properly exploited. Today, there are available technologies to turn thepolymeric structure into building blocks for the production of biofuels and chemicals,suggesting a new conception of process integration, which has been denominatedBiorefinery. This work screened the state of art of the ethanol productiontechnologies from lignocellulosic biomass using patent applications in the BrazilianInstitute of Industrial Property (INPI) until the year of 2009. The work is shared inthree topics: Pretreatments, enzymes production and ethanol production processes.There are 36 applications of pretreatment technologies which 75% belong toAmerican continent institutions (20 North American and 7 Brazilian) and most of itdealing with diluted acid pretreatment. On the subject of enzyme production there are38 patent applications and, among these, 14 belong to Danish companies, focus onNovozymes with 12 applications, and 7 to North Americans. Most of theseapplications are related with cellulases and hemicellulases utilization on the textileindustry. On the ethanol production processes from lignocellulosic biomass there are31 patent application and, in this case, Brazil is has the majority (12 applications),followed by United States (9 applications) and Finland (3 applications). It is notoriousthe expertise of the Brazilian institutions on the production of first generation ethanol,which is being transferred to the second (agricultural residues) and third generations(macroalgaes).143
