“…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%.…”
