RESUMO:

The development of energy production and its consumption have become a major concern for humanity, international public policy agendas have encouraged the replacement of non-renewable energy sources for the diversification of the electrical matrix with the inclusion of renewable energy. The use of biomass becomes an attractive solution for energy generation due to its CO2 neutrality, low pollutant emissions and its renewability. The use of bovine manure for the conversion of energy and products with greater added value are extremely important for sustainable development. Catalytic pyrolysis is currently gaining prominence in a thermochemical conversion process that uses the aid of a catalyst to selectively improve the quality of products. The use of zeolites has been very promising in the catalytic pyrolysis process. Thus, this work will evaluate the catalytic efficiency of Beta and ZSM-5 zeolites in the pyrolysis of cow dung for the production of bio-oil. Zeolites were obtained via hydrothermal synthesis, catalytic pyrolysis was performed in a microscale reactor and their products were characterized by GC/MS. All materials showed crystalline and textural phases referring to the Beta and ZSM-5 structure. The chromatographic profile of the crude and acetylated manure showed alterations, the acetylated manure showed an increase in the formation of esters, furans and sugar derivatives due to the acetylation process that increased the accessibility of the lignin and the compounds generated by the catalytic pyrolysis formed aromatic hydrocarbons with high levels promising octane ratings for the production of biofuels. The materials obtained have high potential in the pyrolysis process and good selectivity for hydrocarbons.
