Abstract

Here is the first report on the non oxidative conversion of methane to larger hydrocarbons in a "one-step" process over Pt-Co/NaY bimetallic samples at low temperature. When the methane is pulsed in a H2/helium mixture at 250°C, the maximum activity being at 1.3 vol. % hydrogen content, higher hydrocarbons are produced during the hydrogen assisted methane chemisorption. The "one-step" process is primarily assigned to the metallic cobalt particles whose reduction is facilitated by the presence of platinum. The effect of hydrogen on the "one-step" methane conversion is discussed in terms of the CHx surface species in which 2 ≥ x > 0 controlled by the relative hydrogen coverage.
