Preparation and catalytic evaluation of catalysts for water gas shift reaction for Co removal from reformed fuels

Abstract EN

A series of Cu-based mixed oxides was investigated for the development of active Cu catalysts for the “water gas” shift reaction (WGSR).

Tri-metallic catalysts active for WGSR were obtained after high temperature calcination at 900 ºC and subsequent reduction.

The results were compared with commercial Cu / ZnO / Al2O3 catalyst and prepared Ru / TiO2 / Al2O3 catalyst.

The prepared catalysts were characterized by temperature programmed reduction, XRD, and sorption analyzer.

Near equilibrium conversion of CO was achieved by the prepared catalysts around 250 ºC.

The Ru-based catalyst showed maximum CO conversion around 300 ºC with some methanation activity, whereas Cu-based catalysts produced a negligible amount of methane in the product stream.
