Ru–Ni/MgAl2O4 structured catalyst for CO2 methanation

Novel catalytic systems should be tested for the valorization of CO through the Sabatier reaction, since this process is gaining great importance within strategic sectors of the chemical industry. Therefore, this work explores the feasibility of structuring a catalyst (0.5%Ru–15%Ni/MgAlO) for CO met...
