Direct conversion of methane to methanol in a flow reactor

Partial oxidation of methane using a microscale non-equilibrium plasma reactor

“…CO X vs. liquid sum. DBD: this work and Larkin et al [21], thermal reaction: Bjorklund et al [7], Dooley and co-workers [5], and Yarlagadda et al [30]. Fig.…”

“…Detailed mechanistic studies that involve labeled molecules with isotopic atoms are possible [28,29], but they are beyond the scope of the present study. [5,7,30] and DBD [21]. Reaction conditions in thermochemical methods were 300-600 8C and 0.1-6 MPa.…”

Recent Advances in Catalytic/Biocatalytic Conversion of Greenhouse Methane and Carbon Dioxide to Methanol and Other Oxygenates

“…The presence of higher hydrocarbons, especially ethane, in small quantities has also been observed to lower the initiation temperature and increase methanol selectivity and yield (Gesser et al, 1985;Fujimoto, 1994). High selectivities of up to 80% for methanol at up to 10% methane conversion have already been achieved under non-catalytic conditions by Gesser et al (Yarlagadda et al, 1988;Hunter et al, 1990;Gesser & Hunter, 1998). It is generally accepted that high pressure favours the formation of methanol and high methane/oxygen enhances methanol selectivity but lowers methane conversion in gas phase homogeneous partial oxidation of methane (Zhang et al, 2003(Zhang et al, , 2008.…”

Direct methane conversion to methanol. Final report, July 19, 1990--May 18, 1996

“…Hunter et al (8), and Yarlagadda et al (9), using pressures from 2 to 12.5 MPa and temperatures from 625 to 755 K, observed CH30H selectivities over 80% at C& conversion levels up to 10%. Hunter et al (8) also observed that the addition of sensitizers (e. g., higher hydrocarbons) to the system reduced the reaction temperature and increased the selectivity to CW3OH.…”
