| Resumo: | The catalytic cracking of triglycerides presents itself as a possible alternative to the
production of biofuels with low emission of pollutants. In this work were synthesized the
SAPO-5, the catalysts for the cracking reaction of soybean oil is presented. The solids were
powder X-ray diffraction (XRD), thermogravimetric analysis (TG/DTG) and infrared
spectroscopy (FTIR). The analyses indicated that the synthesis method has employed to
obtain materials with high surface area and high acid. The soybean oil thermal and thermal
catalytic cracking, realized from the room temperature to 450 ºC in a simple distillation
system, has allowed obtaining two liquid fractions, each consisting of two phases, one
aqueous and another organic, organic liquid (OL). The OL obtained from first fractions has
shown high acid index, even in the thermal catalytic process. The products obtained in the
cracking of soybean oil were analyzed by distillation, acid number, infra-red spectroscopy,
density, viscosity, carbon residue, cetane number determination and characterization. The
analysis of the products obtained in the presence and in the absence of the SAPO-5 permitted
to conclude that all the solids tested presented catalytic activity in the deoxygenation of final
products only at the second step of the cracking process |
