Abstract

In the present work, novel bi-metallic catalysts for syngas
production at low temperature steam reforming are developed,
characterised and tested. Steam methane reforming by using
bi-metallic Ni-Cu catalysts found to balance the product of CO
to CO2 ratios, while affected the water gas shift reaction by
increasing the hydrogen selectivity up to 600°C. The addition
of different amounts of Cu (3, 5, 7, 10 wt%) to the Ni catalyst for
methane steam reforming showed different reactivity trends.
One of the major outcomes of this work is the maximum
load capacity of Cu (5wt.%Cu) to maintain the reactivity. For
comparison purposes, mono-metallic catalysts of Cu and Ni
were developed and tested along with the bi-metallic ones.
The activity of the reaction decreased by doping more than
5wt.%Cu which affected the amount of hydrogen produced.
This is related to the possible limited number of available sites
required for hydrogen adsorption to maintain the reaction of
methane steam reforming. Another important outcome of this
work is the bi-metallic Ni-Cu catalysts did not decrease the
amount of carbon formation.
