Resumen en portugués Realizaram-se na ausência de O2 reacções entre misturas de metano e He e carvão activado oxidado, por varrimento contínuo de temperaturas. Observou-se a ocorrência de três tipos de reacções: formação desprezável de etileno a baixa temperatura, formação de CO, CO2, H2O, C3H8 e C4H10 a média temperatura, que cessou com o aumento da temperatura da reacção e formação de C2H4 e C2H6 a alta temperatura, que se manteve com o aumento da temperatura de trabalho. (mas) Discutem- se dois mecanismos de reacção: um que pode explicar a formação desprezável de C2H4, C3H8 e C4H10 e outro que pode explicar a formação sustentada de C2H4 e C2H6. Os resultados evidenciam a possibilidade de valorização simultânea de metano e carvão. Resumen en español Se realizaron reacciones en ausencia de O2, entre mezclas de CH4 con He y carbón activado oxidado, haciendo un barrido continuo de temperaturas. Se observó la presencia de tres tipos de reacciones: a baja temperatura, formación agotable de etileno; a temperatura media, la formación de CO, CO2, H2O, C3H8 y C4H10 que cesaron al incrementar la temperatura de reacción, y a temperatura alta se formaron C2H4yC2H6 que se mantuvieron al incrementar la temperatura de trabajo. (mas) Se discuten dos mecanismos de reacción: uno que podría explicar la formación agotable de C2H4, C3H8 y C4H10, y otro que podría explicar la formación sostenida de C2H4 y C2H6. Los resultados evidencian la posibilidad de valorización simultánea de metano y carbón. Resumen en inglés The partial oxidation of methane was studied by reactions in absence of O2, between methane diluted with helium and oxidized carbon. In each reaction the molar fraction of methane was held constant while the temperature was modified continuously. The method probed to be useful to distinguish the presence of three kinds of reactions: one at low temperature with the exhaustible formation of C2H4, other at medium temperature that led to the formation of CO, CO2, H2O, C3H8yC4 (mas) H10 and other at high temperature that led to the formation of C2H4 y C2H6; the products at low and mediumtemperature disappeared as the temperature increased while the products observed at high temperature increased with the increase in temperature. Two mechanisms of reaction are proposed: one of them could explain the discontinuous formation of C2H4, C3H8 and C4H10 at low and medium temperatures; the other could explain the formation of C2H4 and C2H6 at high temperature. The results show the possibility of simultaneous valorization of methane and carbon.
