Fig. 14 shows the features of the catalysts prepared for trireforming
including: (A) CO2-TPD over supports and
supported Ni catalysts; (B) CO2-TPD over supported Ni
catalysts; (C) TPR over Ni catalysts supported on different
supports; and (D) carbon deposits analysis on the used catalysts
by TPO-IR after tri-reforming reaction.
Over 95% CH4 conversion and about 80% CO2 conversion
can be achieved in tri-reforming over Ni catalysts supported on
an oxide substrate. The type and nature of catalysts have a
significant impact on CO2 conversion in the presence ofH2Oand
