	abstract = "<P>The thermal cracking of n-butane was compared with both thermal and catalytic n-butane oxidative dehydrogenation reactions. It was found that thermal oxidative dehydrogenation of n-butane was highly selective to n-butenes (approximately 70%) in the conversion range of 11&#150;20%. This reaction proceeded at lower temperature than the thermal cracking of n-butane without oxygen. These results suggest that both reactions have different initiation steps. In the thermal cracking of n-butane the reaction initiated by the C&#150;C bond scission, whereas for the thermal oxidative dehydrogenation of n-butane the removal of the hydrogen atom by the molecular oxygen to form {\dot{C}}_{4}H_{9} and H{\dot{O}}_{2} radicals was proposed as the main initiation step. On the other hand, butadiene was only obtained via a catalytic pathway, being strongly dependent on the reaction conditions.</P>",
