摘要：
Ru-promoted Ni-Co catalysts supported on MgO-Al2O3 are tested for dry reforming activity in a fixed-bed reactor at atmospheric pressure. The effect of temperature and contact time is investigated, and the catalysts maintain high stability for up to 47 h on stream. The support surface area significantly affects dispersion, and whisker carbon is observed in spent samples with pore sizes higher than 15 nm. H-2-TPR studies reveal the presence of spinels that are not completely reducible, yet the catalysts give remarkable activity. Four synthesis methods are tested for the support, with the sol-gel method in neutral conditions providing the best performance, with a small compromise on activity but a significant improvement in catalyst stability and no whisker carbon formation. Further work will optimize the Ni/Co ratio in the active phase to decrease the carbon buildup on the catalysts. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
