Direct conversion of syngas into aromatics over a bifunctional catalyst: inhibiting net CO release

Tandem catalysis via methanol intermediate is a promising route for the direct conversion of syngas into aromatics. However, the simultaneous formation of CO 2 is a serious problem. Here, we demonstrate that CO 2 was formed by the water-gas shift (WGS) reaction (CO + H 2 O → CO 2 + H 2 ) over a ZnO-...

Description
Summary:Tandem catalysis via methanol intermediate is a promising route for the direct conversion of syngas into aromatics. However, the simultaneous formation of CO 2 is a serious problem. Here, we demonstrate that CO 2 was formed by the water-gas shift (WGS) reaction (CO + H 2 O → CO 2 + H 2 ) over a ZnO-ZrO 2 /H-ZSM-5 catalyst, and the net CO 2 formation could be inhibited without affecting the formation of aromatics by co-feeding CO 2 . Co-feeding of CO 2 did not affect syngas conversion to aromatics but significantly suppressed CO 2 formation over bifunctional ZnO-ZrO 2 /H-ZSM-5 catalyst.
