nterest in developing alternative energy sources is increasing due to depletion of oil resources and global warming.
Therefore, fuel cells, which are new energy conversion and storage devices with low emission of pollutants, are emerging
as an alternative. The process of producing hydrogen as a fuel of fuel cells requires a great deal of cost. Therefore, researches
are being studying on reforming catalysts for converting natural gas rich in reserved into hydrogen energy and for use in
fuel cells. In general, a transition metal (Ni, Co, Cu) or a noble metal (Ru, Pd, Pt) is used as a methane steam reforming
catalyst. The noble metal catalyst has excellent catalytic activity and resistance to carbon deposition. But it is becoming a
stumbling block to commercialization due to expensive cost. Ni-based catalysts are less expensive than noble metals and have
a simple manufacturing process, but the problem of degradation due to carbon deposition and grain growth is pointed out as
a disadvantage. In this study, Ni/MgO composite reforming catalyst activated Ni catalyst by exsolution was manufactured to
improve durability. The size and amount of precipitated Ni particles were controlled by the reducing temperature and time.
The catalytic activity and durability of the catalysts prepared as above were evaluated. The conversion rate of methane was
measured and evaluated in the temperature range of 250-750
o
C and methane:water vapor = 1:2 atmospheres with catalyst in
fixed bed reactor. The microstructure and distribution of the produced catalyst were confirmed by XRD and SEM.
