Acesso em:.https://repositorio.ufpa.br/handle/2011/14394In this work, a biofuels study was carried out by the pilot scale thermo-catalytic cracking process, of the residual fat from the fat boxes of the university restaurant of the Federal University of Pará (RU-UFPA), using activated red mud as a catalyst. The residual fat used in the experiments was treated by sieving, decantation, dehydration and storage, to be introduced into the cracking reactor. The red mud was subjected to a pre-treatment of dehydration in an oven at 100°C for 24 hours, then subjected to a chemical treatment with 0,5M, 1M and 2M hydrochloric acid solution (HCl). Subsequently calcination of this material was carried out at 1000°C for 2 hours, to be applied as a catalyst in the proportions 5%, 10% and 15% m/m. The cracking process was performed at a fixed temperature of 550°C, and the generated PLO was collected by reaction time 10 at 20, 40, 60 and 80 minutes, these were then characterized and subjected to fractional distillation. Distillation was performed on a Vigreux column with 12 stages, and condensed fractions were collected according to the distillation ranges of gasoline (45°C-175°C), kerosene (175°C-235°C), light diesel (235°C-305°C) and heavy diesel (>305°C), to be characterized later. The highest yield (PLO + gas) was from experiment 5 with 90%, prepared with 15% m/m catalyst treated with 1M HCl. Also presenting biofuels with better physical-chemical characteristics such as the acid value of gasoline in point 4 (9,4 mg KOH/g) and composites with the highest of 92.91% of total hydrocarbons for kerosene.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Craqueamento Termo-CatalíticoGordura residualBiocombustíveisLama vermelhaProduto líquido orgânicoThermo-catalytic crackingResidual fatBiofuelsRed mudOrganic liquid productTeseCNPQ::ENGENHARIAS::ENGENHARIA QUIMICA::PROCESSOS INDUSTRIAIS DE ENGENHARIA QUIMICA::PROCESSOS BIOQUIMICOSENGENHARIA DE PROCESSOSUSO E TRANSFORMAÇÃO DE RECURSOS NATURAIS
