Abstract In this work, the reforming of model biogas was investigated on a Rh/MgAl 2 O 4 catalyst. situ transient and steady‐state diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) measurements were used to gain insight into reaction mechanism involved in activation CH CO . It found that proceeds through an initial pathway which methane are both dissociated Rh metallic sites additionally bifunctional is activated basic support surface via formate intermediate by H‐assisted...
The bi-reforming of methane (BRM) has the advantage utilising greenhouse gases and producing H2 rich syngas. In this work Ni stabilised in a pyrochlore-double perovskite structure is reported as viable catalyst for both Dry Reforming Methane (DRM) BRM. A 10 wt.% Ni-doped La2Zr2O7 pyrochlore was synthesised, characterised tested under reaction conditions its performance compared to supported Ni/La2Zr2O7. particular effect steam addition investigated revealing that increases content syngas but...
Two Zr-modified alumina supports were synthetized containing the same amount of Zr but a different distribution this modifier over surface. These supports, together with unmodified carrier, used to prepare three cobalt-based catalysts which characterized and tested under relevant Fischer–Tropsch conditions. The presented very similar porosity cobalt dispersion. addition nor its enhanced catalyst reducibility. activity was superior when using carrier consisting large ZrO2 islands use...
The impact derived from incorporating water into CH 4 /CO 2 biogas stream for the generation of syngas was investigated over Rh/MgAl O catalyst using operando steady-state and transient DRIFT spectroscopy coupled with MS.
