Catalytic performance of Ni-Cu/Al2O3 for effective syngas production by methanol steam reforming
Abstract
This work investigates the catalytic performance of bimetallic Ni-Cu/Al<sub>2</sub>O<sub>3</sub> catalysts for syngas production by methanol steam reforming. The synthesis and characterization of a series of Ni<sub>x</sub>-Cu<sub>y</sub>/Al<sub>2</sub>O<sub>3</sub> catalysts with various stoichiometric fractions (x=10, 7, 5, 3 and 0 wt% and y=0, 3, 5, 7 and 10 wt% to Al<sub>2</sub>O<sub>3</sub> support, respectively) are investigated and discussed. The catalytic performance is evaluated experimentally at temperature range of 225–325 °C. Both mono-metallic catalyst (10wt%Cu/Al<sub>2</sub>O<sub>3</sub> and 10wt%Ni/Al<sub>2</sub>O<sub>3</sub>) and bi-metallic catalysts (7wt %Cu-3wt%Ni/Al<sub>2</sub>O<sub>3</sub>, 5wt%Cu-5wt%Ni/Al<sub>2</sub>O<sub>3</sub> and 3wt%Cu-7wt%Ni/Al<sub>2</sub>O<sub>3</sub>) are synthesized using an impregnation method and characterized by means of SEM, temperature programmed reduction (TPR), BET analysis, XRD and TGA. It is found that the bimetallic Ni-Cu catalyst had a strong influence on the amount of CO<sub>2</sub> and CO produced due to the different selectivity towards the water gas shift reaction and methanol decomposition reaction. The increase of the Ni content leads to an increase in CO and decrease in CO<sub>2</sub> yields. The bimetallic catalyst did not produce CH<sub>4</sub>, revealing that Cu alloying in Ni catalyst had an inhibiting effect for CO and/or CO<sub>2</sub> hydrogenation.
