“…Direct thermal cracking can develop methane decomposition at relatively high temperatures (above 1,000 • C) with reasonable conversion rates, thereby providing suitable methane residence times into the reactor (Abánades et al, 2011) or very high temperatures (more than 1,500 • C, when reaction kinetics are very fast). There were even some proposals of a pilot-plant design for direct methane decomposition (Rodat et al, 2011).…”
