“…Different product yields like solid residue and fuel oil are recovered. The remaining value is accounted as non-condensable pyro-gas [14]. The fuel oil production from the feedstock quantity and quality of the final product varied from optimizing and changing the different process parameters for this experiment.…”

The application of bio-oil is possible by increasing quality of bio-oil and adds its durability. Pyrolysis of biomass along with some proportions of plastic waste increases the quality of bio-oil and is termed fuel-oil. On the basis of characterization of Mixed plastic wastes (HDBE; PP; LDBE) and lignocellulosic biomass (sawdust, red gram stalk, Melia dubia, and coconut husk) are arrived as 25:75; 50:50: 75:25:100:0 to recover fuel oil at a varied temperature range from 400 to 550°C with the increment of 50°C in a laboratory set up. The solid residue (char), liquid material(fuel-oil), and gas (pyro-gas) are the products of the pyrolysis process. The maximum fuel oil is recovered with a ratio of 75 % mixed plastic waste and 25 % biomass. FT-IR analysis confirms the presence of alkanes, alkanes and aromatic hydrocarbons in the obtained fuel-oil.

“…Quanto maior o aumento de temperatura, maior será a formação de gás e menor será o ganho de líquido, deve-se ao aumento das reações de craqueamento, contudo, para diminuição do teor de oxigênio é exigido do processo uma alta temperatura, por isso é muito importante ter atenção com as reações de craqueamento (MORTENSEN et al, 2011). Diversos estudos têm mostrado cada vez mais as possibilidades de utilização das zeólitas, sendo um campo com constantes avanços (KURNIAWAN et al, 2021;FERMANELLI et al, 2021;WIKBERG, 2019;CHEN et al, 2018;HERNANDO et al, 2018;VESES et al, 2016).…”

Este trabalho teve como objetivo definir o melhor solvente extrator e sistema de extração para determinação dos compostos fenólicos totais, capacidade antioxidante e antocianinas monoméricas totais do fruto do grumixama. Foram testados diferentes solventes (água, acetona, etanol e metanol), utilizados individualmente e em misturas, bem como diferentes sistemas de extração (agitação magnética à temperatura ambiente, agitação magnética sob refrigeração e escuro e banho ultrassônico à temperatura ambiente). Os resultados mostraram que a acetona / água (80:20, v / v) e a agitação magnética à temperatura ambiente maximizaram a extração dos compostos fenólicos totais e proporcionaram a maior capacidade sequestrante do radical DPPH.Para as antocianinas monoméricas totais, etanol 1,5 M HCl e metanol 1,5 M HCl demonstraram os melhores resultados como solventes de extração. Esses resultados indicam a influência de solventes e sistemas de extração aplicados no rendimento e qualidade dos extratos, além de reforçar o potencial da fruta grumixama em relação ao seu conteúdo fenólico e capacidade antioxidante.

“…Zeolite cracking typically takes place between 300 o C and 600 o C at atmospheric pressure over a zeolite catalyst. HZSM-5 is the common catalyst used in this reaction, which is also applicable in the FCC industry 69 . Mortensen et al (2011) 69 stated that an increase in temperature results in a decrease in oil production and an increase in gas production.…”

According to Energy Outlook 2019 published by the US Energy information administration, aviation fuel consumption is expected to be more than double by the year 2050 as compared to the current usage. The increased cost of petroleum fuels and growing environmental concerns have made the aviation industry rely on biofuel in their fuel usage. Non-edible crops and algae are mainly used as feedstock for jet fuel production. There are many technologies such as blending Fatty Acid Methyl Esters (FAME), lipid hydroprocessing, Fischer-Tropsch synthesis, upgrading pyrolysis oils, Hydrothermal Liquefaction for jet biofuel production. However, sustainable production of jet biofuel is still under research. The current paper discusses the opportunities and challenges with these technologies.
