Abstract:
The conversion of methane to hydrocarbon (C2+) via the oxidative coupling of methane is typically accomplished using high energy due to the temperature of the operation (more than 700°C). A hybrid catalyst consisting of 15 wt% of Ni on Al2O3 (15Ni/Al2O3) and 10-25 wt% of Co supported on Al2O3 (Co/Al2O3) packed as a prioritized layer in a reactor was investigated for the conversion of methane to C2+. Effects of operating conditionsincluding different Co loading in Co/Al2O3, reactor pressure and temperature, percentage of O2 in the feed, total feed flow rate, and different weights of Co/Al2O3on the performance of the hybrid catalyst were studied for the reaction. The highest performance (3.65% C2+ yield with 7.89% C2+ selectivity and 46.26 % CH4 conversion) of the hybrid catalyst was achieved at 6 bar, 490°C, 37.5% of O2 in feed, a total flow rate of 50 ml/min, and using 0.25 g of 15Ni/Al2O3 and 0.1 g of 15 wt% of Co/Al2O3 (15Co/Al2O3). The prepared catalysts were characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, N2-sorption analysis, X-ray photoelectron spectroscopy, and thermogravimetric analysis to acquire the chemical and physical properties of the catalysts. A time-on-stream testing of the optimized hybrid catalyst for 24 h was performed to determine the stability of the catalyst and revealed that the formation of coke caused a rapid deactivation of the catalyst.
