Evaluation of Co-Ni/Sc-SBA-15 as a novel coke resistant catalyst for syngas production via CO2 reforming of methane
The performance of novel mesoporous Co-Ni/x%Sc-SBA–15 (x=0.0, 2.5, 5.0, 7.5 and 10.0) catalysts, prepared
by hydrothermal method, was investigated for syngas production via methane dry reforming with CO2. Several
techniques such as BET, TPR, XRD, CO2-TPD, H2-TPD, TGA/DTA, and TEM were used to characterize the catalysts.
The bimetallic species were successfully immobilized by anchoring into the mesoporous hexagonal network
of SBA-15. Catalytic experiments conducted at 700 and 800 °C clearly revealed high coking resistance of
Co-Ni/Sc-SBA-15 catalyst as demonstrated by TGA/DTA and TEM. Endurance tests undoubtedly demonstrated
that the incorporation of Sc in SBA-15 support remarkably enhanced the catalyst performance by transforming
the stable carbon deposits into active carbon (inhibition of coke formation); thus achieving excellent stability in
dry reforming of methane.
20% iron catalysts supported on combined alumina and silica through different proportions (Al2O3:SiO2:
100:0.00, 90.0:10.0, 80.0:20.0 and 0.0:100.0) were tested for the catalytic…
A novel approach to the in situ regeneration of a spent alumina-supported cobalt–iron
catalyst for catalytic methane decomposition is reported in this work. The spent catalyst was
