Preasphaltenes and asphaltenes were carbonized at inert atmosphere at temperatures of 350, 400 and 450 °C during 180 min. The mesophase identification and quantification was performed by polarized light microscopy. The results showed that the highest concentration of mesophase (79% v/v), with mass yield of 12,4% w/w, was obtained from the asphaltenes treated at 400 °C. The highest mesophase global yield (with respect to coal fed) was 4,4% w/w. 2014 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43030033009 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.70 |
