Fig. 7. Experimental non-oxidative methane coupling results using Fe@CRS catalyst in a fixed-bed reactor.

a CH₄ conversion and b C₂H₆, C₂H₄, C₂H₂, and C₆H₆ selectivities as functions of catalyst contact time and gas-phase residence time. Data points are shown as white circles. Reaction conditions: T = 1293 K, P = 0.1 MPa, total residence time in the heating zone = 1.7–59.6 s, catalyst loading = 0–1.2 g.
