In recent years, hydrogen energy is considered as an alternative energy to solve the depletion of fossil fuel. Steam Methane Reforming (SMR) is widely known as cost-effective method for hydrogen production. Ni catalyst with best activity is widely used for SMR reaction. However, It has severe problems such as carbon coking and sintering at high reaction temperature resulting in reducing the SMR performance. In this study, we developed the Ni-La catalyst supported on hierarchically alumina to prevent catalyst deactivation for enhancing durability. The optimum content of La was added in Ni catalyst with best catalytic performance for high hydrogen production. The as-prepared Ni-La showed high mass transfer capacity and minimizing carbon coking and sintering of Ni, resulting in enhancing catalytic activity and durability. |
