The homogeneous partial oxidation of a methane-containing paraffinic hydrocarbon.

摘要

A C2 and higher hydrocarbon product including ethylene is produced from a methane-containing gaseous paraffinic hydrocarbon feedstock by a process comprising heating the feedstock admixed with oxygen in an amount of at least 5% mol under elevated pressure in a pre-heating zone to a temperature sufficient to cause spontaneous reaction, the pre-heating and mixing being effected in a manner such that (i) substantial oxygen consumption is avoided, and (ii) a "flash-back" of the reaction to form a diffusion flame at the point of gaseous mixing is prevented, and thereafter in a reaction zone allowing the feedstock mixture to spontaneously react.
