Supercritical Water Ethanol Reforming for Hydrogen Production: (Effect of Different Support on Nickel Based Catalyst in Supercritical Water Condition)
Asian Journal of Chemistry,
Vol. 22 No. 1 (2010): Vol 22 Issue 1, 2010
Abstract
The aim of this work is to study the behaviour of different supports
of nickel based catalyst for hydrogen production by supercritical water
reforming of ethanol in high pressure. Catalytic tests have been performed
at laboratory scale under high pressure and supercritical water condition.
Catalyst characterization was carried out to identify catalytic properties
such as, surface area, temperature programmed desorption (TPD) and
temperature programmed reduction (TPR). The analyses of liquid and
gas were carried out in different G.C. In present condition, the support
effects well the physical and chemical properties of catalyst. γ-Alumina
and YSZ increase the acid sites. The composition of product and production
of hydrogen varies with different support. ZrO2 and YSZ make
easier the reduction of nickel oxide at temperature blow 500 ºC and
increase the ethanol conversion and hydrogen production. The product
composi-tion depends not only to temperature but also to the degree of
nickel oxide reduction over support. In low temperature, nickel oxide
favorite production of C2H4, C2H6 and heavier compounds. ZrO2 and
specially YSZ are the best support to produce hydrogen with less carbon
monoxide.
