Abstract
|
In the recent years vast verities of industries are paying more attention to the
production of syngas (hydrogen and carbon monoxide) by using partial oxidation
catalytic reaction of methane. As a result of availability and low price of nickel metal
in comparison to the rare-earth metals nickel is the most common used catalyst in the
process of partial oxidation of methane. To add appropriate promoting as well as that
the choice of proper catalytic support will be able to increase the activation and
stability of nickel’s catalyst. In this study firstly catalytic support SBA-16 was prepared
after that Ni/SBA-16 catalyst with ceria copper copper-ceria promoter were
synthesized by the impregnation method that was used in partial oxidation of methane
reaction (POM). The properties of prepared catalysts were characterized by N2
adsorption (BET) and XRD techniques. The catalytic performance of samples was
evaluated in a fixed-bed micro-reactor and Conversion of CH4 in the temperature range
of 700 to 850?C was obtained. The obtained results showed that the methane
Conversion didn’t change with the addition of ceria at the molar ratio of Ni/Ce of 1/1.
However Cu to Ni/SBA-16 catalyst in the same ratio and also Cu-Ce can dramatically
decreased activation of catalyst. Furthermore Comparison of methane Conversion on
the SBA-16 supported catalysts with the similar catalysts supported on SBA-15 can
indicated superior performance of SBA-16 as a catalyst support in catalytic partial
oxidation of methane.
