Abstract: Study on the use of copper zinc oxide supported on alumina catalyst for
steam reforming of methanol to hydrogen has been done. The aim of this work is
to study the catalytic properties of copper based catalysts used in the steam
reforming of methanol. This method is known as one of the most favorable
catalytic processes for producing hydrogen on-board. The catalyst was prepared
by impregnation method
with Cu loading
of 5%, 10%,
and 15%,. The
X-ray diffraction pattern shows
that the catalyst
compositions are Cu,
CuO, ZnO, and Al2O3. The reactions
were carried out
in the fixed
bed tubular reactor
operating at temperatures
of 150oC, 200oC, 250oC, 300oC,
and 350oC and atmospheric pressure.
The product was analyzed using
Shimadzu Gas Chromatography GC 8A with
mole sieve 5A
and porapak-N column 80/100
mesh. The performance
of the catalyst
shows that the
highest methanol conversion was 86%
over Cu/ZnO/Al2O3 catalyst
with 15% of
Cu loading. The
selectivity and yield
of hydrogen was 66% and 57% respectively over Cu/ZnO/Al2O3
catalyst with 15% of Cu loading. Selectivity
of carbon dioxide
is 18% over
Cu/ZnO/Al2O3
catalyst with 15%
of Cu loading
at 300oC.
