Abstract
The main research objective is to study the hydrogen production and more particularly to
examine in details the effect of reaction conditions on the catalytic processing of methane
decomposition. The H2 production were conducted in a quartz tube fixed bed reactor over three
kinds of catalysts Fe/AC(Locally prepared), γ-Al2O3 and Activated Carbon(AC) (Commercial).
The Fe/AC catalyst were prepared by a precipitation method and characterized by BET. The
reactions were carried out under atmospheric pressure and at different temperature (800, 850,
and 900 OC) with different VHSV(Volumetric Hourly Space Velocity), the outlet sample were
measured using H2 Analyzer. The results exhibit that the highest H2 Production (26.3 %) was
obtained over local AC ,when the CH4 decomposition was (41.7%) at the following conditions:
temperature: 900°C ,VHSV 3.6 and 6.0 l/h g.
