Carbon dioxide reforming of methane over Ni/θ-Al2O3 catalysts: Effect of Ni content

at973 K for 2 h prior to each catalytic measurement. Effluentgases from the reactor were analyzed by a gas chromato-graph (Chrompack CP9001) equipped with a thermal con-ductivity detector (TCD). GC column used in this study wasa Fused Silica capillary column (CarboPLOT P7). The BETspecific surface areas were measured by nitrogen adsorptionat 77 K using a Micromeritics instrument (ASAP-2400). TheNi surface area was calculated according to the reference
