PROCESS FOR THE OXIDATIVE COUPLING OF METHANE TO HIGHER HYDROCARBONS

摘要

AN IMPROVED PROCESS FOR THE OXIDATIVE COUPLING OF METHANE TO HIGHER HYDROCARBONS An improvement in the process for the oxidative coupling of methane is provided. Typically, the reaction takes place in a reactor that includes a catalyst zone. A primary CH4/O2 stream is fed into the entrance of the reactor and reacted at a temperature of 600.degree.C-1000.degree.C and a pressure of between 101 kPa and 800 kPa. The improvement comprises introducing an auxiliary oxygen stream directly into the catalyst zone and one or more points to thereby selectively increase the yield of C2+ products.
