Changing the catalyst backbone from Al2O3 to MgO is very promising due to the appreciable CO2 capture capacity of MgO as well as the low technological demand for recycling of spent catalysts. Due to the caustic properties of MgO based catalyst systems a product yield close to equilibrium conversion can even be obtained at moderate operation pressure. Exemplarily Ni doped MgO catalysts offer great performances in methanation of CO2 at ambient pressure. For catalyst optimization the Ni-load of MgO has been varied between 11 wt% and 27 wt%. For methanol synthesis the catalyst performance of Cu/MgO and Cu/ZnO/MgO systems has been investigated and compared.
