Some Characteristics of the Partial Oxidation of CH4 to CH3OH at High Pressures
The direct conversion of methane to methanol by the partial oxidation process at high pressure has been studied for about 60 years [1,2,3,4] but in the last 5 years more has been published [5–27] than in all previous years. The discrepancies in the results obtained by different workers seems to have been explained by the cool flame characteristics of the system, first described by Yarlaggada et al.  and later shown by Foulds et al.  and Charlton et al.  to exhibit to a hysteresis effect with change in reaction temperature. More recently, high selectively and conversion were obtained by Dooley  by using a pre-heater to accommodate the induction period, and a post reactor temperature quencher to prevent further oxidation of the methanol.
