Abstract—Dry reforming of methane (DRM) is an
environment friendly process since it utilizes two major
greenhouse gases (CH
4 and CO
2) to produce valuable syngas.
Polyol process was adopted to prepare nano supported (Al
2O
3,
ZrO
2 and CeO
2) Ni based nano catalysts for DRM reaction. All
catalysts were prepared in ethylene glycol medium with
polyvinylpyrrolidone as a nucleation-protective agent. The
main objective of this study was to develop a suitable catalyst,
for syngas production, which possessed high activity, stability
and minimum coking rate during DRM. The catalytic activities
of the prepared catalysts were evaluated in the temperature
range 500-800°C. The obtained results revealed that catalytic
performance depends on the nature of support. Amongst all
tested catalysts, Ni-Zr Pol showed highest activity (87.2%) and
stability (%D.F= -0.46). On the other hand Ni-Al Pol catalyst
exhibited acceptable activity (84.8%) with minimum coking
rate (0.015 g/g
cat.h) while Ni-Ce Pol showed smallest activity
(83.2%) with large amount of coke deposition (0.025 g/g
cat.h).
