Title
Oxidative steam reforming of ethanol over PtRu/ZrO2 catalysts modified with sodium and magnesium
Abstract

This paper reports the catalytic performance of a PtRu/ZrO2 catalyst modified with Na and Mg in an oxidative steam reforming of ethanol (OSRE) reaction tested in the temperature range of 300–400 °C. The results show that the PtRuMg1/ZrO2 catalyst requires higher temperatures (TR ~ 400 °C) to achieve complete conversion than either the PtRuNa1/ZrO2 or PtRu/ZrO2 catalysts (TR ~ 300 °C). Also, an apparent coke deposit is found on the PtRuMg1/ZrO2 catalyst. The preferential PtRuNa1/ZrO2 catalyst shows active at temperatures as low as 300 °C and produces less CO (< 0.2%) at temperatures lower than 340 °C.

Graphical AbstractAn effective performance for the oxidative steam reforming of ethanol (OSRE) has been succeeded development over PtRu(Na, Mg)/ZrO2 catalysts. It is found that the preferential PtRuNa1/ZrO2 catalyst shows active at temperatures as low as 300 °C and produces less CO (< 0.2%) at temperatures lower than 340 °C.Figure optionsDownload full-size imageDownload as PowerPoint slideResearch Highlights► PtRu(Na, Mg)/ZrO2 catalysts for the oxidative steam reforming of ethanol. ► Addition of sodium can improve the catalytic behavior at low temperature. ► The PtRuNa1/ZrO2 produces less CO (< 0.2%) at temperatures lower than 340 °C.
