Web24 nov. 2013 · Temperature characterizing the methane pyrolysis is 1,500–2,000 K, but plasma temperature is in the range of 4,000–5,700 K, which means that methane pyrolysis process is occurring outside the plasma region in the swirl gas flowing around the plasma. Introduction Webexperimental studies on pyrolysis in liquid metal media were performed. Steinberg’s studies [13, 14] can be considered as a new step of studies on the use of a molten metal for solving the problem of carbon deposition in the reaction volume in the course of noncatalytic methane pyrolysis. Methane was fed into the lower part of the reactor and
Web10 mrt. 2024 · In the experiments shown in Fig. 3, methane was introduced into a 1 m long glass tube with a diameter of 22 mm at 1030 °C to 1092 °C. The differences within the five experiments in the data of Lucas et al. are mainly due to different temperatures, volume flows and reaction times. WebPyrolysis generally consists in heating the material above its decomposition temperature, breaking chemical bonds in its molecules.The fragments usually become smaller molecules, but may combine to produce residues with larger molecular mass, even amorphous covalent solids.
