Abstract
We studied methane pyrolysis of at 750 to 1100°C on a heat-treated FeCrAl wire heated by electric current both in the absence of oxygen and at CH4 : O2 = 15 : 1 and 9 : 1. The process proceeds in two temperature ranges differing in pyrolysis product selectivity. In the transition region, intensive carbon deposition occurs on the wire surface. The presence of oxygen shifts the methane conversion versus temperature and product selectivity versus temperature curves to higher temperatures. We believe that the existence of two process regions is due to the coking of the catalyst surface.
