The byproducts of oil refining industries and biodiesel, as the dregs of neutralization are quite extensive and due to their low economic value and purity are a problem for these industries in the culling and disposal, are of fundamental interest for the use of this research reject. Therefore, this work aims to investigate a viable, economic and environmental fate of this byproduct using Termocatalítico Cracking Process of Neutralization Sludge Palm Oil (Elaeis guineensis Jaqc) pilot scale using 5, 10 and 15% sodium carbonate (Na2CO3) as catalyst and final temperatures of 440 ° C and 420 ° C. The sludge was obtained by the neutralization process and subjected to a dehydration and characterized as the catalyst was dried in an oven and characterized in relation to the X-ray diffraction, Thermal Gravimetric Analysis (TGA) and Differential Thermal Analysis (TDA). Five tests were performed in termocatalítico cracking Cracking Pilot Plant (THERMTEK / FEQ / UFPA) which consists in a reactor with mechanical agitation and capacity 125 liters, and the dynamics of the process and distillation of cracking. The organic liquid product (PLO), samples of the dynamics of the process and the distillation fractions were characterized according to each standard required by ANP N°65 and analyzed by IR and NMR. After analysis of the results showed that the efficiency of the process increases with temperature and catalyst and the feedstock provides products of low acidity and good characteristics for use as fuel. By analyzing the thermodynamic realized that some of the process parameters such as viscosity, flash point and density decrease with increasing time and temperature, forming lighter hydrocarbons. Regarding distillation fractions in the heavier tracks resemble diesel oil in most of the parameters required by the ANP Nº 65.
