Avaliação do desempenho de Pt/NTCPM como catalisador para produção de bio hidrocarbonetos a partir de óleo de vísceras de frango

Drop-in biofuels are composed by synthetic bio-hydrocarbons and are the only alternative to substitute fossil jet fuel, since they can meet to rigid specifications required to aviation fuels. This type of biofuels can be produced by different routes. Hydroprocessing can produce bio-hydrocarbons from vegetable oils and animal fats, in the presence of a catalyst, at high temperatures and pressures. The efficiency and cost of this process is related to the utilization of an efficient catalyst and a cheap raw material. In this work, it was investigated the utilization of a carbon nanotube supported platinum (Pt/MWCNT) catalyst to convert poultry viscera oil, a waste from chicken meat production, into biohydrocarbons. The results of reactions with 5 wt% of catalyst, at 350 °C and under 30 bar H2 showed the Pt/MWCNT efficiency to promote deoxygenation reactions, while MWCNTs appear to have catalytic activity to triglycerides cracking reactions. Therefore, the use of this nanocatalyst and poultry oil seems to be a promising alternative to produce biojet fuels. However, to achieve higher degree of deoxygenation, it is necessary to study the influence of some process variables, such as pressure, time reaction and H2/raw material ratio.
