Abstract
|
Reports
a study of the characteristics of catalytic partial oxidation of methane
(CPOM) under CO2 addition and excess enthalpy recovery using a rhodium-based
catalyst. The influences of O2/CH4 and CO2/O2 molar ratios, in the ranges of
0.4–0.7 and 0–2, respectively, on CPOM performance was emphasized. The energy
efficiency of the Swiss-roll reactor was studied as well. Results revealed
that the O2/CH4 ratio plays a crucial role in methane conversion, whereas it
is insensitive to the CO2/O2 ratio.
Overall, CPOM performed at O2/CH4 = 0.6 is recommended in that it provides higher CH4 conversion, syngas production, CO2 consumption, and system energy efficiency. |
