Effect of potassium loading on basic properties of Ni/MgAl2O4 catalyst for CO2 reforming of methane

Coke deposition is one of the key issues in the dry reforming of methane on Ni catalysts. In the present work, we investigate the effect of potassium addition for suppressing carbon deposition in the Dry Reforming of Methane. The results obtained demonstrated that potassium contents above 3 wt% prom...
