Pyrolysis of used sunflower oil in the presence of sodium carbonate by using fractionating pyrolysis reactor

Energy from Waste Materials and Unconventional Sources

“…There are many studies that have investigated the thermal conversion (pyrolysis and cracking) of triglycerides for obtaining hydrocarbon fuels (Alencar et al 1983;Ali and Hanna 1994;Dandik and Aksoy 1998;1999;Gusmao et al 1989;Kubicka et al 2010;Lima et al 2004;Maher and Bressler 2007;Schwab Simacek et al 2009). Results showed that conversions ranged between 54 and 100 % and were heavily dependent on operating variables.…”

Lewis acid catalyzed diesel-like fuel production from raw corn oil

“…It was reported that there has been a plethora of research on the efforts to use various catalysts for the pyrolysis of triglycerides [9]. The pyrolysis of triglyceride in the presence of activated alumina [10], sodium carbonate [11], transition metal [12], and molecular sieve [13] has been studied for the production of diesel-like hydrocarbons.…”

Production and Characterization of Green gasoline Obtained by Thermal Catalytic Cracking of Crude Palm Oil (Elaeis guineensis, Jacq.) in a Pilot Plant

“…Wiggers et al (2009) [12] realized a thermal cracking of soy oil and fry oil at 525ºC obtaining as results, products similar to gasoline and fractions of petroleum diesel. Dandik and Aksoy (1998) [13] measured the conversion of residual sunflower oil by cracking with temperatures between 400 and 420ºC, using as catalysts, the sodium carbonate, aluminium silicate and HZSM-5, with the obtaining maximum percentage of liquid hydrocarbons about 32.8%, being confirmed the presence of hydrocarbons on the range of gasoline. Twaiq et al (2004) [14], studied the performance of materials containing ZSM-5 on the palm oil cracking, being those performances compared to HZSM-5 and MCM-41 catalysts, obtaining as result a conversion of the palm oil equal to 80% and a gasoline fraction yield of 38 to 47%.…”
