RESUMO

The purely thermal cracking of castor oil produces a mixture of compounds with unsatisfactory fuel properties, as high viscosity, high acid value and low cetane index. This low quality is associated with high value of oxygenated products in obtained product composition. The aim of this work was to improve the physical-chemical properties of cracking product (pyrolysis) of castor oil using different catalysts, such as silica and silica doped with titanium(IV) oxide, and alumina and alumina doped with zinc(II), tin(II), titanium(IV) and zirconium (IV) oxides. The study of the physicalchemical properties of the castor oil cracking products showed that all these catalysts have activity in the deoxygenation, being the better results reached using pure and doped alumina.
