Biogas reformation over pr-promoted ni/mgo

Promoting rare earth element into commercial catalyst has become interesting research in designing the best catalyst for methane dry reforming. 1wt%, 3wt% and 5wt% Pr loadings into Ni/MgO were prepared by wet-impregnation method and calcined at 973 K. The prepared catalyst was characterized using N2...
