Abstract Methane pyrolysis in an externally heated tubular reactor inevitably ends with clogging of the reactor. Thin molten metal wall films protect walls from carbon depositions. A falling film and a rotating are investigated by CFD simulation. The results show considerable advantages compared to vertical An alternative route for production methane is implementation exothermic chlorination re...
