“…Pyrolysis conversion is one of the most promising methods that can directly convert biomass into liquid fuels called bio-oils, which runs at 350–600 °C in the absence of oxygen. 1 It draws much attention because of its short residence time, 2 easy separation of products, 2 and wide range of feedstock 3,4 compared to other methods. Bio-oil is a complex mixture of sugars, esters, furans, acids, ketones, alcohols, phenols, guaiacols, and so on.…”

“…However, a significant reduction of water content in the oil obtained was observed only when the HZSM-5/50 catalyst was used at a temperature of 555 °C, where its value was about 3.97 wt %. Hilten et al 45 noted that the reduction of water content in catalytic cracking was due to the formation of hydrocarbons. As reported by Sharma and Bakhshi, 19 a small amount of water, approximately 2−5 wt %, will still remain in the oil after catalytic cracking.…”

Oil from the pyrolysis of biomass typically consists of two different layers defined as the aqueous and organic phases. The objective of this study was to determine the yield of liquid fuel that can be produced from the aqueous phase using a catalytic conversion. The process was supported by two different HZSM-5 catalysts with temperatures set at 405, 455, 505, and 555 °C. The oils obtained were then analyzed using Karl Fischer titration, FTIR spectroscopy, GC/MS, TGA, and CHNS/O analysis. The results showed that the oil yields obtained from catalytic cracking of the aqueous phase ranged from 4 to 9.16 wt % depending on the catalyst type and temperature. The optimum performance of deoxygenation activity was obtained with the HZSM-5/50 catalyst at a temperature of 555 °C. The oil produced under the optimum conditions was dominated by aromatics and phenols and had an HHV of 38.44 MJ/kg.

“…Obtiveram um bio-óleo com poder calorífico superior de 36,1 MJ/kg, porém com uma viscosidade alta de 37,8 cSt devido à alta quantidade de ácidos graxos saturados. Na sequência, Hilten et al (2010b) adotou uma outra abordagem e fez um craqueamento catalítico do bio-óleo produzido por Smith et al (2009) para tentar melhorar a qualidade. Hilten et al (2010b), em seu estudo sobre o resíduo de tratamento de efluentes de indústria de produção de aves, comparou o catalisador de FCC com o HZSM-5 e constatou que o catalisador de FCC tem uma menor formação de coque e, consequentemente, gera levemente mais produtos líquidos e gasosos.…”

A utilização do catalisador de FCC no processo de craqueamento de biomassa tem um bom fundamento, pois este já é aplicado em larga escala no processamento de petróleo.…”

Biofuels have been occupying space in the fuel market as a renewable substitute for petrol fuels. The thermal and/or thermo-catalytic cracking using triglyceride biomass stands out among the biofuel production processes. Cracking processes result in the production of coke, bio-oil and non-condensable gases. The quantification of each product in a cracking process is directly linked to operational conditions. This project focuses on the use of residual fat from the poultry processing industry, converting it into biofuel so that it can be used in the industry itself as a source of energy. The quality of the products generated are linked to the raw material used, as well as the conditions used in the cracking process. One way to improve the characteristics of the bio-oil produced can be achieved with the use of a catalyst together with thermal cracking. The literature has shown that in thermo-catalytic cracking, there is lower yield in bio-oil, but with some properties, such as acidity and viscosity closer to the value required by legislation for use in engines. This project aims to add value to an industrial waste, by converting this waste into biofuel using thermo-catalytic cracking, with the possibility of being used in the industry itself, as well as investigating the optimization of the process to improve the quality of bio-oil. The yield of the liquid fraction was around 67 % with an acid value of 58.74 mg KOH/g sample.
